Multi-Functional Pump Control Valve (JD/H 745X)

Product Description:

Connection dimension of flange:
PN1.0MPa, PN1.6MPa to GB4216
PN2.5MPa to GB9113

Purpose:

For the pump room of water catchment, water carriage, and sewage treatment systems in the fields of city planning, mining industry, enterprises, high buildings and power station.

Suitable temperature: ≤ 80º C

Advantages:

. High security. It has the functions of quick closing and slow closure and absorbing energy cavity to avoid the water hammer. Operation is full interlocking and there isn't wrong operation.
. It is unnecessary to control while the pump start and stop. The medium and the pressure difference of the both ends of the valve are skillfully used to make the valve automatically operate according to the water pump operation rules.
. It isn't necessary to professionally debug. The valve isn't affected by the change of head of liquid, water pressure and flow of pump. It has a large adaptive scale. Generally it isn't necessary to care. Can be used for a long time.
. Effectively save energy. Enter into the diaphragm support plate by the pressure of the entry end. The loss of resistance is small.
