Self-pressure regulating valve supplied with tank temperature can be used continuously at 350 ℃ steam. Shanghai a loop fluid control equipment Limited production of self-pressure regulating valve is widely used in urban heating, heating systems and petroleum, chemicals, power, metallurgy, food, light industry and other industrial equipment in gas, liquid, steam, etc. medium pressure, discharge valve, constant pressure.
Self-pressure regulating valve without external energy, energy use was transferred media itself as the power source, the introduction of the actuator control spool position, changing pressure and flow at both ends, so that (or valve after) the valve before the pressure is stable. A sensitive, good sealing, small fluctuations in pressure set point, etc., are widely used in gas, liquid and steam medium voltage vacuum regulator or relief automatic control. The series of self-regulating valve with a single seat (ZZYP), sleeve (ZZYM), two-seater (ZZ
YN) three structures: a thin film type actuator, piston type two kinds: the role of the type after decompression valve pressure regulator ( B type) and pressure relief valve before the pressure regulator (K type). Nominal grade products have PN1.6,4.0,6.4; body diameter range of DN20 ~ 300; leakage levels have Class II, IV and VI can be third gear stage; quick opening flow characteristics; pressure segment is adjustable from 15 ~ 250MPa . Users may need to meet the conditions required combination.
