Self-operated regulator control valve Feature

Self-operated regulator control valve which can adjust the pressure as the set value with it’s medium own energy and without any outer energy.The most advantages of this Self-operated regulator control valve is that it can be suitable for the working place of no power and no pneumatic equipment available, additional,Self-operated regulator control valve can save energy for the end-user, and the pressure is adjustable within the set range.

Self-operated regulator control valve has the following types according to the different working conditions:

ZZYP(single-seat type), ZZYM(sleeve type) and ZZYN(double-seat type), and Self-operated regulator control valve also has three different covers such as common one, long-neck one and cooling type. For different applications, this Self-operated regulator control valve has three different types of actuators:film/piston/bellows.

This Self-operated regulator control valve has other advantages as smart and accurate regulating,taking up small space and simple operation and it’s widely used in the pressure control of gas,steam or water in petroleum, chemical, electric power, metallurgy, food, textile, machinery, civil construction industry.

Self-operated regulator control valve is designed and manufactured according to the standard of AMSE/API/BS/DIN/GB
