As a control component in the fluid conveying system, the valve has the functions of cutoff, regulation, diversion, prevention of countercurrent, shunt, pressure relief, etc., there are many kinds and various specifications. With the continuous development of valve technology

After the installation of the steam solenoid valve, it is necessary to pass the medium to test the operation for several times, and it can be put into formal use after confirming that it is normal.

High pressure butterfly valve leakage is a more common problem, but in some important systems and equipment, high pressure butterfly valve leakage will affect industrial production and serious some will also endanger the safety of people's lives and property. The high and middle pressure butterfly valve is connected

What is the difference between butterfly valve and gate valve? The difference between the two is not well understood by the average layman. In fact, in terms of use, the flow resistance of the gate valve is relatively small, and the sealing performance is better.

Under normal circumstances, the valve is not tested for strength, but the valve body and valve cover after repair or corrosion damage of the valve body and valve cover should be tested for strength. For safety valves, the constant pressure and return pressure and other tests shall comply with the specifications and relevant regulations.

First, electric valves are usually composed of electric actuators and valves. Electric valve uses electric energy as power to drive the valve through the electric actuator to achieve the valve switching action. Thus to achieve the purpose of switching the pipeline medium.
