The gate valve is a shutter of the opening and closing member. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted and throttled.

The gate of the gate valve moves linearly with the valve stem, which is called the rising stem gate valve. Usually, there is a trapezoidal thread on the lifting rod, and the rotary motion is changed into a linear motion by the nut at the top end of the valve and the guide groove on the valve body.

The double-cut discharge slab gate valve with diversion hole is mainly used to cut off the medium. It is a kind of industrial valves and is used in many industrial fields, such as natural gas and petroleum.

The industrial gate valve refers to a valve in which the closing part (gate) moves in the vertical direction of the center line of the passage. The gate valve can only be used for full opening and full closing in the pipeline, and cannot be adjusted and throttled. The gate valve is a kind of valve w

Valve professionals often refer to the term "internal" when talking about industrial gate valve. But they are not talking about the pros and cons of valve assembly, but rather the internal components that are subjected to extreme stresses or harsh conditions that combine corrosion and corrosion.

The gate valve has not changed much in the past 100 years, but it has played an important role in the production facilities of refineries, chemical plants, power stations and industrial enterprises around the world.

In the use of electric industrial butterfly valve, the use environment is often damaged due to leakage problems, so preventing leakage is an important problem that needs to be solved by electric butterfly valves. Introduce several methods that can effectively solve the leakage of electric butterfly valves.

The structural characteristics of the high temperature and high-pressure hard seal ball valve is difference from soft seated ball valve, following features we could figure out the differences and help know more about the hard seal industrial ball valve.

Ball valves were introduced in the 1950s. The industrial ball valve is a kind of industrial valves. With the rapid development of science and technology, the continuous improvement of production technology and product structure has rapidly developed into a major valve category in just 40 years.

What are the technical difficulties of high-temperature three-eccentric metal hard-seal butterfly valves? What problems have been encountered in design and development? How to solve them?
