ZJHM type fine small pneumatic sleeve regulator
Structure features and application range
ZJHM type small pneumatic sleeve regulator, by the pneumatic diaphragm spring more actuators and low flow resistance sleeve of regulating mechanism. Compared with the normal sleeve valve, 1/3 has small volume, large flow characteristics of 1/3, widely used in the demands of low noise, large pressure differential industrial process automatic control system.
