Fast-Acting Panel-Mount Threaded On/Off Valves
Open and close these valves with the flip of the toggle switch. Commonly used for equipment testing and gas sampling, they have threads and a hex nut below the handle for installation in instrument panels.
316 stainless steel valves are more corrosion resistant than brass valves.
Manual-return valves remain open or closed when the toggle is moved into position.
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.
- Valve Type: Stem
- For Use With:
Buna-N Rubber Seal: Water, Oil, Air
All Other Valves: Water, Oil, Air, Argon, Helium, Krypton, Neon, Xenon

Gradual On/Off Valves with
Quick-Clamp Fittings for High Vacuum
Also known as vacuum isolation valves, these block flow so you can install and remove gauges from your system. They can also be used to add or vent gases in high-vacuum systems. Valves gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow. They connect to another quick-clamp fitting with a clamp and a ring (sold separately). All have a nonrising stem that stays in the same position whether the valve is open or closed. Body is 304 stainless steel for good corrosion resistance.

Use these rings with quick-clamp high-vacuum fittings. They consist of a stainless steel inner ring covered by a fluoroelastomer O-ring.
Rings with screen have a stainless steel screen to filter out large particles.
Pressure-rated rings have an aluminum outer ring to withstand extra pressure.
