Model:
Diaphragm type self-operated regulator which can adjust the pressure as the set value with it’s medium own energy and without any outer energy.The most advantages of thisDiaphragm type self-operated regulator is that it can be suitable for the working place of no power and no pneumatic equipment available, additional,Diaphragm type self-operated regulator can save energy for the end-user, and the pressure is adjustable within the set range.
Diaphragm type self-operated regulator has the following types according to the different working conditions:
ZZYP(single-seat type), ZZYM(sleeve type) and ZZYN(double-seat type), and Diaphragm type self-operated regulator also has three different covers such as common one, long-neck one and cooling type. For different applications, this self-operated control valve has three different types of actuators:film/piston/bellows.
This Diaphragm type self-operated regulator 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.
Diaphragm type self-operated regulator is designed and manufactured according to the standard of AMSE/API/BS/DIN/GB
