| ZZYRessure adjusting valve in own power |
|
ZZY Ressure adjusting valve in own powerdoes not need else power resources,its drive resourcescomes from its own energy,then entering the position of administration cotrol valve,so the pressure reduction and the flux of both poles are changed,therefore,the pressure in front of valve(rear valve)is on balance. it has better charactors,for example,action sensitive,better airtightness,little shock on pressure position。it is widely used in aeriform, liquid and steamy mediums for reducing pressure and stablishing pressure.
