Needle Valves
Parker needle valves are used to control or regulate the flow of liquid and gas, as well as provide a tight shut-off mechanism for positive sealing in instrumentation and metering applications. These units come equipped with a handwheel or small handle designed specifically to control the position of the plunger and allow precise and accurate fluid control. They feature 316 stainless-steel / brass / PFA construction for withstanding pressures ranging between 100 and 6000 psi and a maximum temperature of 450 degrees F. Choose from an extensive range of these slender needle-shaped plungers available in R, N and K type stem tips on Raptor Supplies.
