Applications: for industrial combustion systems, control of two materials, such as gas, air flow ratio, in order to achieve ideal combustion for hydrogen-cooled generators seal oil system seal when the low pressure side of the differential pressure valve is vented micro pressure. valve (differential pressure valve negative pressure side pressure, force is zero) safe: no electric for the occasion, there is no external energy risks to save energy: the need for external energy, the use of piping, pressure regulating simplify system: No external control instruments , no filler, there is no valve stem friction, reliable sealing actuator sensor is extremely sensitive and tiny pressure changes can be sensed out pressure adjustment is extremely convenient, without having to stop production to adjust the technical parameters set value differential mode operation pressure regulating function of U relief or security, D regulator or valve seat structure P single seat seal level Ⅲ, Ⅳ, Ⅵ C- V- micro-pressure valve differential pressure valve-seat difference N- (micro) pressure regulator valve normally open and normally closed two kinds of body parameters nominal PN1, PN10 flanged connections, (special: welded) Body material 1Cr18Ni9Ti, Cr18Ni12Mo2Ti Spool Material 1Cr18Ni9Ti, Cr18Ni12Mo2Ti, Stellite surfacing sealing material PTFE hard seal, a special high-temperature materials Bellows pushrod bushing 2Cr13 1Cr18Ni9Ti Diaphragm NBR (NBR) Flange standard GB9113-88, JB / T79-94, GB2555-81 fluid temperature ≤80 ℃ - band conductor, micro Q- completely cut off pressure regulator solenoid valve solenoid valve http://www.electricvalve.cn/xiaofangdiancifa/ www.electricvalve.cn fire way solenoid valve http://www.electricvalve.cn/santongdiancifa/ gas solenoid valve http: //www.electricvalve.cn/ranqidiancifa/ stainless steel solenoid valve http://www.electricvalve.cn/buxiugangdiancifa/
