Check valve can regulate the opening and closing speed. When the pump starts or stops running, it can be adjusted to the best opening or closing speed with the on-site adjustment.It is suitable for mining enterprises and high-rise buildings to reduce water hammer and water hammer in direct water supply and drainage system by water pump, so as to ac1
The 500X relief/hold valve is mainly used in fire fighting or other water supply systems to prevent system overpressure or to maintain pressure in fire fighting water supply systems.
Micro resistance slow closing check valve is a kind of valve.It can be used in the drainpipe line of clean water, sewage and seawater, which can not only prevent the backflow of the medium, but also effectively limit the destructive water hammer and ensure the safety of the pipeline.
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.
Forged steel flanged valves are available in three bonnet designs.The first is the bolted bonnet.The second design is the welded bonnet.The third is the pressure self - tightening bonnet.
Forged steel check valve is to rely on the flow of the medium itself and automatically open, close disc, used to prevent the medium backflow valve, also known as the check valve, check valve, reverse flow valve, and back pressure valve.
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
Welded ball valves are widely use in various fields, Their superior quality and high performance stability are not achieved by ordinary cast steel ball valves, The service life of all welded ball valves is far greater than that of cast steel ball valves, All welded ball valves are widely uesd in city gas, urban heating, petrochemical, shipbuilding,1
