Valve description and operation

YX741X regulator is a kind of hydraulic diaphragm pressure control valve, it is usually installed in the high-rise building water supply system, irrigation water supply system and water pump stations. This valve is hydraulically operated by means of a diaphragm which is set in the interior of the valve, it’s regulation does not need any outer energy. this valve can easily reduce the inlet pressure to the desired set outlet pressure and maintain the outlet pressure at a constant value. the outlet pressure does not change due to the changes of inlet pressure and flow, so it can reduce both dynamic pressure and static pressure to achieve the protection of the waterworks and keep the supply system working stably.

This valve has the advantages of :

1. Accurate regulation and control of the installation: pumps, pipelines, etc

2. Maintenance without being removed from the pipeline.

3. Smooth and secure closure without leakages

4. Long life time of the installations

We have two types structure of this valve, Type Y double chamber and Angle shaped type with single and double chamber.

This valve is designed and manufactured according to the standard of AMSE/API/BS/DIN/GB
