Brief introduction of valve

Jul 03, 2020

Valve A device used to control fluid flow, pressure and flow direction.


Butterfly valveThe butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the opening and closing or adjustment of the valve.


Gate valve The opening and closing part of the gate valve is called the gate. The gate moves up and down and is perpendicular to the direction of the fluid. The gate valve can only be fully opened and closed, and cannot be used for regulation and throttling.


Blowdown valve The blowdown valve is small in size, light in weight, simple in structure, good in sealing, low in material consumption, small in installation size, especially small in driving torque, and easy to operate. The gear rod is rotated 90 degrees to drive the stem to open and close. purpose. Easy to realize fast opening and closing
Globe valve is a widely used valve. Due to the small friction between the sealing surfaces during opening and closing, it is durable, the opening height is not high, the production is simple, the maintenance is convenient, not only suitable for low and medium pressure, but also suitable for high pressure.


Check valve The opening and closing parts rely on the power of the medium flow to open or close by themselves to prevent the medium from flowing back. The valve is called the check valve.


Ball valve A ball valve is a kind of valve that uses a ball with a circular channel as an opening and closing piece. The ball moves with the rotation of the valve stem to achieve the opening and closing action.


Pressure reducing valve The pressure reducing valve achieves the purpose of regulating the flow of the medium by controlling the opening degree of the opening and closing parts in the valve body.


Regulating valve The regulating valve is used to regulate the flow, pressure and liquid level of the medium. According to the signal of the adjustment part, automatically control the opening of the valve to achieve the adjustment of the medium flow, pressure and liquid level.


Balance valve The balance valve is a valve that performs dynamic and static balance adjustment under hydraulic conditions.


Safety valve Safety valve is a fully automatic valve, which does not require any external force, but uses the force of the medium itself to discharge the rated amount of fluid.


Diaphragm valve The opening and closing part of the diaphragm valve is a diaphragm made of soft material, which separates the inner cavity of the valve body from the inner cavity of the bonnet and the driving parts, so it is called a diaphragm valve.


Steam traps Steam traps are used in steam pipe networks and equipment to automatically discharge condensate, air and other non-condensable gases, and to prevent water vapor leakage.


Plug valve The plug valve has a simple structure, quick opening and closing, and low fluid resistance. The plug valve is a valve that uses a plug body with a through hole as an opening and closing member, and realizes the opening and closing action through the rotation of the plug body and the valve stem.


Solenoid valve Solenoid valve is an automatic basic component used to control fluid and belongs to actuator. Solenoid valves are used to control the direction of hydraulic flow. The mechanical devices of the factory are generally controlled by hydraulic steel, and solenoid valves are used. Solenoid valve is not only hydraulic and pneumatic.
