Adjustable Pressure Reducing Surge Damping Valve (YX741X)

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 and industrial water supply etc. Get the upper higher pressure clown to the normal lower working-pressure.

Suitable temperature: ≤ 80º C

Advantages:

. Reliable effect of pressure reduction. The exit pressure will not be affected by the change of entry pressure and flow. Can reduce both the dynamic pressure and the static pressure.
. Be easy to adjust and operate. Can get the exact and stable exit pressure by adjusting the adjustable bolts of the pilot valve.
. Effectively save energy. Adopt the designs of half line sprue runner, wide valve body and same water section. The loss of resistance is small.
. The key parts are made of special material. Generally it isn't necessarv to care.
