Y(B)43X Type Proportional Pressure Reducing Valve (PRV)
Fixed proportional pressure reducing valves are featured by simple structure, elegant profile, dependable quality, accurate proportion, steady operation, and reduction of both dynamic and static pressure.
This kind valve uses the pressure difference caused by different sectional areas of the two ends of piston inside vlave body to change the back pressure of valve for pressure reduction.
