Self-reliance type pressure regulator attached temperature tank can be continuous under 350D
Degree steam. HANGZHOU SOWELL AUTOMATION EQUIPMENT Co., Ltd produced self-reliance type pressure regulator is widely used in urban heating, heating system, petroleum, chemical industry, electric power, metallurgy, food, light industrial equipment gases, liquids, steam and other media pressure relief valves, constant pressure.
SOWELL Self-reliance type pressure regulator without needing external energy, using medium itself power as power supply, leading in actuator control core position, change two ends pressure differential and flow, makes the pressure stable before valve (or after). It has the smart action, good sealing performance, pressure setting point small fluctuations advantages, is widely used in gas, liquid and steam medium depressure stabilizing pressure or automatic control. This series of products are single seat (ZZYP), sleeve (ZZYM), double seat(ZZYN) three structures: Actuators have diaphragm, piston type two kinds: Acting types decompression after valve pressure regulating (B type) and pressure regulating before pressure relief valve (K type). Nominal pressure rating has PN16, 40, 64, Valve size range DN20 ~ 300, Leakage class is class II, level IV and VI, Flow characteristic is fast opening, Pressure section adjustment is 15 ~ 250Mpa. Can combine according to need in order to meet user requirements. Technical parameters and performance indicators
