Threaded On/Off Valves for Natural Gas and Propane
- Valve Type: Plug
- For Use With: Natural Gas, Propane
Also known as plug valves, these are often used as a mainline shutoff in natural gas and propane pipelines.
Lockable T-handles can be fixed in place using a padlock (not included) with a shackle diameter up to 1/2”.

Easy-Set Threaded Precision Flow-Adjustment Valves
- Valve Type: Needle
- For Use With: Water, Oil, Air, Argon, Helium, Krypton, Neon, Xenon
- Seal Material: Fluoroelastomer Rubber
The color-coded threads and numerical markings on these valves ensure consistent and repeatable settings. One full revolution of the handle reveals a new color to indicate the set point. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Valves have metal-to-metal seats that resist temperature fluctuations.
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.
