Pressure Reducing Proportional Valves
Brand: Parker HannifinParker’s family of proportional pressure reducing valves give the operator reliable performance for applications that require pressure limitation.
These valves are capable of handling flows up to 37 lpm (10 gpm) and pressures as high as 210 bar (3000 psi).
Parker’s proportional pressure reducing valves are ideal for pilot control or functions such as cylinders where there may be a risk of buckling due to over-pressurization, and can be paired with any Current Controlled Pulse Width Modulation (PWM) valve driver.
The simple and compact design enables these valves to be used on a variety of equipment within the mobile, industrial, or manufacturing markets.
