ZJHP (M) type single seat pneumatic (sleeve) by the pneumatic spring diaphragm actuator and low flow resistance through single seat control valve (valve sleeve valve), single seat valve body through single seat cover guide structure, as the plunger type valve structure, compared with the ordinary single seat valve has the advantages of small volume, light weight, characteristics applicable to the traffic flow and so on, leakage of demanding applications. Compared with the ordinary sleeve valve, the ZJHM type fine small sleeve has the characteristics of small size, light weight 1/3 and large flow 1/3, and is widely used in the automatic control system of the industrial process with low noise and large pressure difference.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
