ZMHN direct action pressure adjusting valve, need not external energy and operated media, automatically operated according to the energy of controlled fluid and keep variable constant of valve behind or valve front, to automatic adjust non-etching gas, oil, steam that temperature under 200 ℃. Simple structure 、reliable movement、convenient maintenance, fire and explosion, low cost and other advantages .
Working principle
The regulated signal that directly acting on pressure adjusting valve can be get from valve back tube channel , increasing follow the adjusting pressure, overcome the force of hammer, valve spool moves down, getting closed Gradually with the valve seat , so that flow cross-section decreases, valve spool moves up, flow cross-section increases until  adjusted pressure is equal to the given value
Adjusting range: No. 1 film Room:0.5~1.3; No. 2 film Room: :0.1~0.5; No.4 film room : 0.015~0.1MPa,
