How to Selection and installation of forged steel gate valve
Forged steel gate valve is mainly used to cut off or connect the medium in the pipeline, not for regulating or throttling. According to different methods, gate valve can be divided into parallel gate valve, wedge gate valve, lifting gate valve, rotary rod gate valve, quick opening and closing gate valve, necking gate valve, flat gate valve, etc.
- The installation position, height, inlet and outlet direction shall meet the design requirements, and the connection shall be firm and tight.

What is the function of the foot valve?
The Foot valve consists of valve evaluation, disc, bonnet, bushing, sealing ring and other parts. See the water from the water source in the figure below from the bonnet to the valve body. Under the action of fluid pressure, the valve disc opens water.
When the pressure in the outlet pipe closes the valve disc rapidly after stop, the liquid will not be poured back to the water source, which plays the role of unblocked pumping and saving water energy loss.
- Check valves should be installed on equipment, installations and pipes to prevent medium backflow.
- Check valves are generally suitable for cleaning media, not for media containing solid particles and high viscosity.
- Vertical lift check valves should be generally used in horizontal pipelines with nominal diameter of 50mm.

Ball Valves vs Gate Valves,Which is best for you?
In the market, the valve products are more. Generally, there are many ball valves and gate valves. For those who want to buy two products, they will know what kind of use and function and the difference between the two before buying. How to choose good quality ball valve and gate valve. For this reason, I have summarized some knowledge about ball valves and gate valves. Just tell you the difference between a ball valve and a gate valve? What should you pay attention to when using the gate valve?
1, gate valve
The advantages of the gate valve are small resistance, tight shut-off, and no water hammer, which are widely used in various liquid and gas shut-off valves. It also has a certain adjustment function, but when it is partially opened, the shutter is easily wetted by the fluid, and when the fluid flows, it will cause the board to vibrate and the sealing surface is easy to wear.
The gate valve is one of the commonly used shut-off valves. It is mainly used to turn on or off the medium in the pipeline, and is not suitable for regulating the flow of the medium. The valve is suitable for a wide range of pressures, temperatures and calibers, especially for medium and large diameter pipes.
2, the ball valve
(1) The ball valve has a simple structure, the ball valve is lighter in weight than the gate valve, the structure is relatively simple, and the overall weight is very light, so it can exert a good effect in the low temperature medium system; the sealing surface is easy to process, and the sealing property is good. Easy to operate, quick switch, short start-up and shut-down time, can quickly optimize the test system, and no impact during valve start-up and shutdown.
(2) It can not be used to adjust the flow rate. It is suitable for high pressure (up to 320 gauge) pipelines. Currently, it can only be used below 200 °C due to the limitation of sealing materials. It can also be used for suspensions and viscosities. Medium. Moreover, its adjustment performance is worse than the shut-off valve, especially the pneumatic valve (or electric valve).
Stv Valve Technology Group has a full line of gate valves and ball valves, in addition to many other types of valves. See what we have here.

Manual Butterfly Valve Dimensions
The opening and closing part of manual butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or regulating.
The butterfly plate of the manual butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc butterfly plate rotates around the axis, the rotation angle is between 0 and 90 and when the rotation angle is between 0 and 90 the valve is fully open. The butterfly valve is simple in structure, small in volume and light in weight, and consists of only a few parts. The valve can be switched on and off quickly only by rotating 90 degrees. The operation is simple and the valve has good fluid control characteristics.
