ANSI Self Operated Pressure Regulator
ZZY series self operated difference (little) Pressure Control Regulating valve Can be used in nominal pressure PN0.1 , PN10. The difference (little ) presses the regulation of segmenting. From 50mm.WC to 0.1MPa. self operated type difference (little ) Regulating valve of the pressure The use is...
ZZY type Self - pressure regulating valves require no additional energy,The actuator products of automatic regulation are realized by using the energy of the regulated medium itself.This product is the most characteristic,can work in the place without electricity, without gas, but also saves energy,pressure setting value can be adjusted freely in operation.Use quick opening traffic characteristics, action quick, sealed performance is good, so it is widely used in petroleum, chemical, electric power, metallurgy, food, textile, machinery manufacturing and resident building blocks and other industrial equipment used in gas, liquid and steam decompression, medium voltage (for valve after adjustment), or pressure, voltage regulator (used in valve regulating) automatic control.
