Product Description

No matter what the upstream pressure is, the downstream pressure will reduce proportionally to a target pressure and sustain / keep the downstream pressure stable.

PROPORTIONAL PRESSURE CONTROL VALVESREDUCING/RELIEVING.Proportional Pressure Control, Reducing/Relieving, Internal Pilot Operated pressure control valve. 

groups include Proportion control valve, pneumatic proportional valve, pid regulator, proportional pressure reducing valve, the proportions of the fixed type pressure reducing valve, electric regulator, type gas valve, proportion type electric control valve, proportional valve, proportional pressure reducing valve group.

Structure and function

YB43X, YB13X proportional-type reducing valve.This valve is mainly constituted by the body, inlet flange, piston, large cylinder sleeve, small cylinder sleeve, outlet flanges and o-shaped rings, sealing gaskets, etc. proportional reducing valve makes use of different sectional area of two float piston ends to constitute the front-back pressure difference, and change the back-pressure to achieve the purpose of pressure-reducing. Proportional reducing valve is of unique structure, superior performance, large flow, switch smooth, without noise, stable ratio of reduced pressure namely: "reducing dynamic pressure" and "reducing static pressure", and has function:reduce and eliminate the phenomenon of water hammer to water supply pipe, eliminate the instruments of vibration,protection pipe and water conservation.
Standards pressure ratio for 2:1, 3:1,4:1, 5:1, and 3:5:2 etc, designed according to user's requirements of special proportion of valve.
