Why a ball valve should not be opened incompletely?

Imagine yourself trying to warm your house on a chilly winter’s evening. When you go to the basement to change the heating system, you discover that the ball valve that regulates the hot water flow is only partially open. Although it may appear to be a small detail, there may be serious repercussions.

Ball valves, which control the flow of fluids like gas or water, are essential parts of heating systems. They can lead to a number of issues that are uncomfortable and expensive when they’re not fully opened or closed. Let’s examine the reasons behind the necessity of making sure a ball valve is completely closed or fully open, without any intermediate state.

First and foremost, a ball valve that is partially opened will not allow the fluid to flow through the system as intended. Any blockage in the flow, whether it be gas going to a furnace or hot water going through radiators, can result in inefficiencies. This implies that some parts of your home may remain colder than others due to your heating system’s inability to distribute heat evenly throughout the house.

Furthermore, your heating apparatus may experience needless strain if the ball valve is only partially opened. Consider attempting to sip from a straw that is only partially exposed; this will need more work and may cause frustration. Similar to this, if a ball valve is not fully open, the heating system has to work harder to reach the desired temperature, which could lead to a reduction in equipment lifespan and an increase in energy consumption.

However, the possibility of leaks is arguably the most important reason to avoid partially opening a ball valve. A partially closed valve increases the possibility of gas or water seeping through and causing leaks that could endanger your safety as well as cause damage to your property. Ball valves that are only partially open can have expensive and far-reaching effects, ranging from possible gas leaks to water damage.

The next time you adjust your heating system, keep in mind how crucial it is to fully open or close the ball valves. It’s an easy step that can have a big impact on the safety, energy efficiency, and comfort of your house. The little things can make a big difference in your overall heating experience, so don’t ignore them.

Principles of ball valve operation

A ball valve offers the best possible balance between efficiency and simplicity. There is a type of shutter—a ball with a through hole—within the plastic or metal body. The dimensions of the device’s inlet and outlet match the parameters of this opening. When force is applied to the rotation handle, the ball component, which is fixedly attached to it, rotates.

When the ball is in the "open" position, the liquid medium flows through it without encountering any obstructions. The ball turns "blind side" to the transported medium’s flow and shuts it off entirely if the handle is turned 90 degrees. The medium to be transported has its supply totally cut off.

It is possible to adjust the fluid head’s intensity by turning the lever to lower values.

Advantages and disadvantages of ball valves

Experts in the installation of shut-off equipment, the product’s favorable attributes include:

1. Compact size and low weight indices.
2. High tightness.
3. Can be installed in confined spaces.
4. Good quality at an affordable price.

However, along with the previously listed benefits of this kind of valve are a few drawbacks, which include:

1. The need for high operating torque when the valve is rotated by 90°.
2. Quick opening of certain modifications of the valve at high pressure of the fluid medium can create a probability of hydro-impact.
3. To maintain the functional characteristics of the ball valve, it should be "cranked" weekly.

When it comes to heating and insulating your home, it"s crucial to understand the importance of a properly functioning ball valve. These valves play a significant role in controlling the flow of water or gas in your heating system. One key point to remember is never to open a ball valve incompletely. Doing so can lead to issues like leaks, reduced efficiency, and even damage to your system. By fully opening or closing the valve, you ensure smooth operation and prevent potential problems down the line. This simple but essential practice can save you from headaches and costly repairs, making it a must-know for any homeowner looking to keep their heating system running smoothly.1 / 2

Types of ball valves

Ball valves can be used in a variety of applications. Because of this, their classification range is very broad and is represented in over 4000 different modifications as of right now. Basically, a few of the following factors determine the different types of modern ball valves.

Body material

Different materials can be used to make ball valve bodies, and each has pros and cons of its own:

1. Brass.
   Taps made of brass are designed for installation of gas networks and water supply systems. Optimal price/quality ratio. Not suitable for hot water systems.
2. Steel.
   The most budget-friendly option, available in a wide range of types and sizes. Not suitable steel valves for cold water supply networks, as they are prone to corrosion.
3. Stainless steel
   Taps made of stainless steel are the most efficient but expensive option, suitable for fluids of any temperature and corrosive aggressiveness.
4. Cast iron.
   Obsolete version, with low performance characteristics, almost completely disappeared from the consumer market.
5. Polypropylene.
   Polypropylene valves are designed for installation of plastic pipe systems. Strong and durable, characterized by budget price and light weight. Immune to corrosion. Their main disadvantage is that they can be used only for plastic pipes. It is not possible to equip metal pipes with such shut-off valves.

Connection type

Ball valves are classified according to their types of connections with pipeline communications, and each variety should be taken into consideration independently:

1. Coupling ball valves. Valves with this mounting system are presented in a wide range of types and sizes, equipped with a threaded structure, which has ensured their high popularity in domestic and industrial applications as an element of water flow regulation . The threaded connection provides good sealing performance, while the valve can be easily replaced and mounted.
2. Weld-on valves. They are not very large, lightweight and compact in appearance. The principle of welded installation with the pipeline system provides indicators of absolute tightness. But they can be very difficult to repair or replace.
3. Flanged ball valves. Large, bulky systems. Suitable for installation of large main water supply networks with pipe diameters exceeding 40 millimeters. They are easy enough to install, but need occasional checking of the position of the tightening bolts.

Body type

Ball valves are distinguished, among other things, by the type of their bodies. There are two kinds of construction: fully welded and collapsible. For a collapsible model, a single-piece welded ball valve body is a reasonably inexpensive option. If a valve with such a body breaks, it must be replaced entirely. Such a valve typically lasts for 20 years. The ball valve’s collapsible body is practical because it makes it simple to disassemble and replace any damaged parts as needed.

Control method

Ball valves can be operated in three different ways: pressure-reducing, pneumatically actuated, and electrically actuated, depending on the application. However, we will be looking at how a traditional water ball valve works in this article. This kind of valve is operated and adjusted by hand. By turning the control lever or "butterfly" valve, the flowing media (in this case, water) can be shut off or supplied again.

Type of media passage

The valves are separated into the following categories based on the specifications of the usage technique and the requirement to adhere to specific liquid head parameters:

1. Full bore. In this case, the width of the bore diameter in the inner ball is identical to the dimensions of the inlet and outlet parts of the valve. Optimal for systems where a specific head is important, without intensity drops.
2. Reduced (standard bore). This type of construction implies some difference in the diameters of the inlet holes and the hole in the ball (on average, in the parameters of the same size). Cranes of this type are cheaper, which has ensured their great popularity. A distinctive advantage of the reduced valves is a reduced probability of passing the hydro-impact impact.

Ball valve structure

The following parts make up the ball valve, which is intended for water supply system installation:

• the body itself;
• an internal locking ball made of brass or steel with a passage hole of a certain diameter;
• of the sealing inner washer;
• the external control regulator in the form of a lever or "butterfly";
• of the adjusting metal nut;
• stem for necessary sealing.

When buying a ball valve, it is necessary to check it for dents, cracks, nicks and dings, as well as other defects that may affect the quality and durability of operation. The intended use of the valve can be determined both by the individual characteristics described in the instructions, and by the features of the appearance, in particular, the coloring of the valve. For example, the black or yellow color of the valve indicates that the valve is intended for gas equipment. Red color marking – hot water supply. Blue or blue – cold. Getting this wrong is critical. An incorrectly installed faucet will soon malfunction and can cause leaks and damage to neighbors.

While partially opening a ball valve may seem like a small matter, it can cause big trouble later on. A partially opened ball valve restricts the flow of gas or fluid, which can lower your heating system’s performance and efficiency.

A primary reason to refrain from partially opening a ball valve is to shield the valve from harm. Ball valves work by rotating a ball with a hole through it to regulate the flow of gas or liquid. Uneven wear or vibration of the ball due to a partially closed valve can eventually result in leaks or even total failure.

Additionally, improperly opening a ball valve can lead to problems with the operation of your heating system. Your family may experience discomfort if there is insufficient heating or cooling in your home due to insufficient flow through the valve. Additionally, it may overwork your heating system, reducing its lifespan and raising maintenance expenses.

To guarantee adequate safety, a ball valve should be fully opened. A valve that isn’t fully opened can cause pressure to build up in the system, which raises the possibility of leaks, bursts, or other dangerous scenarios. By fully opening the valve, you lower the possibility of mishaps or malfunctions by enabling a steady and smooth flow.

To sum up, even though it might seem like a minor point, making sure a ball valve is fully opened is essential to the effective and secure functioning of your heating system. Fully opening valves and maintaining your heating system on a regular basis can help you save money on repairs, increase energy efficiency, and guarantee the security and comfort of your house.
