Plastic Threaded Precision Flow-Adjustment Valves
- Valve Type: Needle
- For Use With: Water, Air, Argon, Helium, Krypton, Neon, Xenon
- Seal Material: EPDM Rubber
Plastic provides a lightweight alternative to metal valves. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. These valves have a hex nut and threads below the handle for mounting through instrument panels.

Precision Flow-Adjustment Valves with Push-to-Connect Fittings
- Valve Type: Needle
- For Use With: Water, Air, Argon, Helium, Krypton, Neon, Xenon
- Seal Material: EPDM Rubber
Insert tubing into the fittings on these valves—no heat, solder, or flux required. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. All valves have a hex nut and threads below the handle for mounting through instrument panels.

Threaded Precision Flow-Adjustment Valves for Chemicals
To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a fluoroelastomer seal and a plastic body. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
