Working Principle

The operator turns the hand wheel of the stop valve, and its rotational motion is transmitted to the valve stem with external threads, which cooperates with the internal threads in the valve body to make the valve stem move up and down linearly. The valve stem rises, the valve disc rises, and the fluid channel opens; the valve stem drops, the valve disc presses the valve seat, the channel is blocked, and the fluid is controlled. At the point where the flow needs to be adjusted, turn the hand wheel to control the angle and change the opening height of the valve disc to adjust the flow.

 

 

Materials and Features

01.

Material:

Common materials include cast iron, cast steel, stainless steel, copper alloy, etc. Cast iron handwheels are low in cost and suitable for general industrial and civil occasions; cast steel handwheels are high in strength and can withstand large operating torques, suitable for more severe working conditions such as high pressure and high temperature; stainless steel handwheels have good corrosion resistance and are often used in pipeline systems with corrosive media; copper alloy handwheels are used in some environments with special requirements for corrosion resistance and wear resistance.

02.

Features:

Simple structure, easy operation, even in the absence of power supply, the valve can be easily opened and closed by manpower. At the same time, the existence of the handwheel allows the operator to intuitively control the state of the valve, and can roughly judge the degree of opening and closing of the valve and the resistance of the fluid in the pipeline by hand feel.

1. Industrial production: In petrochemical, electric power, metallurgy and other industries, it is used to control the on/off and flow regulation of various fluid pipelines such as oil, steam, water, etc.

2. Building water supply and drainage: Installed in the water supply and drainage system of the building, it controls the switch of water flow to ensure smooth daily water supply and drainage.

3. Heating system: In central heating or independent heating systems, it regulates the flow of hot water and controls the indoor temperature.

4. Special fields: For example, in the fluid control system of ships and aerospace, it manually controls the on/off and flow of specific fluids.

Q: What materials are available for your stop valve handwheels?

A: We offer stop valve handwheels in a variety of materials to meet different usage scenarios and customer needs. Common ones include cast iron, which is cost-effective and suitable for general industrial and civil environments; cast steel, which has high strength and can withstand large operating forces, suitable for harsh working conditions such as high pressure and high temperature; stainless steel, which has excellent corrosion resistance and is often used in pipeline systems with corrosive media; and copper alloy, which performs well in occasions with special requirements for wear resistance and corrosion resistance.

Q: Is the handwheel easy to install? Do you need professional tools?

A: The installation is very simple. Most handwheels use standard connection methods with valve stems, such as common key connections or threaded connections. Generally, you only need a common tool such as a wrench or screwdriver and follow the detailed installation instructions we provide to easily complete the installation. If you have any questions during the installation process, our technical support team is always available to provide you with guidance.

Q: Will the handwheel wear or slip after long-term use?

A: The materials we choose have good wear resistance, and we also put a lot of effort into surface treatment to further enhance the wear resistance. At the same time, the anti-slip design of the handwheel has been carefully considered and tested, and there will be no slipping under normal use. Of course, if your use environment is more special, we can also recommend more targeted wear-resistant and anti-slip solutions to ensure the long-term and stable operation of the handwheel.

Q: Can you provide customized services for handwheels? For example, special size or appearance requirements.

A: Absolutely. We have a professional R&D and production team that can customize according to your special needs. Whether it is special size specifications, unique appearance design, or adding logos and scales to the handwheel, we can meet them. You only need to provide detailed design requirements and drawings, and we will create a dedicated stop valve handwheel for you.
