The hemisphere of the double eccentric hemisphere valve adopts double eccentric design, which has reliable sealing effect, instant release, small torque and long service life. It can be used in harsh working conditions for conveying granular media. The structure principle is that the center line of the hemisphere is offset from the center line of the valve stem, and the size is offset from the cen…

Plug valve (plugvalve), a valve with a plug body with a through hole as an opening and closing part. The plug body rotates with the valve stem to realize the opening and closing action. The small unfilled plug valve is also called "Cock". …

Explosion-proof electric butterfly valve is a special control for flammable and explosive occasions. The explosion-proof grade is ExdII BT4/CT4 or CT5, which has the advantages of stable quality, excellent explosion-proof performance, safety and reliability. In addition, the connection forms and structural forms are also diversified, and are widely used in food, environmental protection, light ind…

Working principle and characteristics of linear electric actuator…

The electric valve is to use an electric actuator to control the valve, so as to realize the opening and closing of the electric valve. It can be divided into upper and lower parts, the upper part is the electric actuator, and the lower part is the valve. It can also be called an air-conditioning valve.…

The electric ball valve has a simple structure, consisting of only a few parts, and saves data consumption; small size, light weight, small installation size, electric ball valve structure diagram, small driving torque, pressure regulating valve, simple and agile operation..…

Valves are used to open and close pipelines, control the flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. The valve is a control component in the fluid conveying system. It has the functions of cut-off, regulation, diversion, prevention of reverse flow, stabilization, diversion or overflow and pressure relief. It can be said that in all as…

Electric actuator is a common driving device, which can accurately control the position of the valve and is a very modern equipment. It can prevent the danger from spreading further and reduce the loss of the factory to a small amount, making it popular among the public.…
