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

Purpose:
For the pump direct water supply and drainage applications in the mining industry and high buildings. Reduce the water hammer in order to safely close.

Suitable temperature: ¡Ü80º C

Advantages:
Can avoid the water hammer and get the effect of slow closure and muffler. Also can protect the pump and ensure the pipe to normally operate. The speed of opening and closing can be controlled.
