Product Description:

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

Purpose:

For the pipeline of fire fighting, domestic water, industring water supphy and sewage treatment. The valve opens and closes by the electric signal and manual operation.

Suitable temperature:
≤ 80º CSuitable medium: Water, oil product

Advantages:

. Exact and quick control
. The speed of closing is adjustable. If the valve doesn't tightly close, the pressure fluctuation will
Not come into being.
. Be controlled by the solenoid valve.
. The sensitivity is high.
