Common Defects and Preventive Measures of Gate Valve

What is a gate valve? A gate valve refers to a valve in which the opening and closing part (valve plate) is driven by the valve stem to move the sealing surface of the valve seat for lifting movement, and a valve that can open or cut off the passage of the fluid. When the […]

Classification and structural characteristics of safety valves

A safety valve is a valve-type overpressure relief device consisting of three main parts: seat, disc and loading mechanism. It is an automatic valve that USES the pressure of the medium itself to discharge a nominal amount of overpressure fluid through the opening of the disc to prevent the pressure in the device from exceeding […]

How do gate valves work?

Do you know the pressure test methods for various valves? (with dynamic map)

In general, strength tests of industrial valves are not taken during use, but the valve body and bonnet that are corroded or repaired should take strength tests. For safety valves, the constant pressure, return pressure and other tests should comply with the specifications and relevant regulations. Valve strength and seal tests should be performed on […]

Selection Principles of Gate Valves

Selection Principles of Gate Valves Advantages of gate valves 1. The medium’s flow direction will not be changed because gate valves belong to the through type valve which also makes gate valves feature in small flow resistance. 2. The sealing performance of gate valves is better than that of globe valves, and the opening and closing […]

What is an angle valve?

What is an angle valve? The angle valve is an angle stop valve. The angle valve is similar to a ball valve. Its structure and characteristics are corrected by the ball valve. The difference from a ball valve is that the outlet of the angle valve is at a right angle of 90 degrees to […]

How do gate valves work?

What are gate valves? Gate valves, or sluice valves, as they are sometimes known, are valves that open by lifting a round or rectangular gate/wedge out of the path of the fluid. They are so named because the part that either stops or allows flow through the valve acts somewhat like a gate. The gate […]
