Electric butterfly valve is a kind of electric valve and electric regulating valve. The main connection methods of electric butterfly valve are: flange type, wafer type and lug type. According to the transmission mode, it can be divided into manual, gear transmission, pneumatic, hydraulic and electric. It is an important execution unit in the field of industrial automation control. Electric butter…

The electric valve simply uses the electric actuator to control the valve, so as to realize the opening and closing of the valve. It can be divided into upper and lower parts, the upper part is the electric actuator, and the lower part is the valve. The action force distance is larger than that of the electric valve, the switching speed of the electric gate valve can be adjusted, the structure is …

Electric gate valve consists of stem, valve body, bonnet, gate, drive and other parts (fasteners, stem nut, sealing packing). Rod (torsion shaft), gate valve is thus divided into two types: open rod gate valve and dark rod gate valve.…

Pilot-operated safety valve (also known as pulse-type safety valve) is a safety valve that relies on the discharge of medium from the pilot valve to drive or control the main valve. The pilot valve itself is a standard spring-loaded safety valve. Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, whi…

The Y-type filter is a necessary filter equipment for the use of hydraulic control valves and precise mechanical products that are easy to block. It is an indispensable device for the pipeline series for conveying the medium. It is usually installed at the inlet end of the hydraulic control valve, pressure reducing valve, pressure relief valve, fixed water level valve and other equipment to elimin…

Forged steel check valve has two body cover connection design forms: one is the body cover bolted forged steel check valve, the valve designed according to this connection form, the valve body and the valve cover are connected by bolts, wound gasket The advantage of sealing is that it is easy to maintain; the second type of forged steel check valve with full welding seal on the body cover, the val…

Do you know the common classification of electric butterfly valve? Electric butterfly valve belongs to a variety of electric valve and electric regulating valve. The main connection methods of electric butterfly valve are: flange type and wafer type; the main sealing forms of electric butterfly valve are: rubber seal and metal seal. The electric butterfly valve controls the opening and closing of …

The electric ball valve has the action of rotating 90 degrees, and the cock body is a sphere with a circular through hole or channel passing through its axis. The main features of the electric ball valve are its compact structure, reliable sealing, simple structure and convenient maintenance. The ball valve in the pipeline is mainly used as an electric ball valve to cut off, distribute and change …
