Internal screw swing check valves refer to opening and closing parts by the flow of media and force to open or close, in order to prevent the media backflow of the valve.
Multifunctional connection gate valve, can be used, installed and replaced in seamless pipe, welded pipe, ductile pipe, cast iron pipe (PVC,PPR,PE pipe, steel plastic pipe), directly reduce flange piece, telescopic device, no need for electric welding butt.
Forged steel gate valves are available in three bonnet designs.The first is the bolted bonnet.The second design is the welded bonnet.The third is a self-sealing bonnet.
Also known as a gate valve, a gate valve is a valve with the shutoff valve moving vertically along the center line of the path.Used for switching on or cutting off media.

A flat gate valve is a sliding valve with a closing part parallel to the gate.The shutoff may be a single gate or a double gate with a bracing mechanism in between.The gate pressure to the seat is controlled by the medium pressure acting on the floating gate or the floating seat.In the case of double gate flat gate valves, the retracting mechanism 1
Controlling the liquid level of water tower or pool is simple to maintain, flexible and durable, high accuracy of liquid level control, water level is not disturbed by water pressure and closed tightly without leakage.
