Plastic Panel-Mount Vacuum-Regulating Valves for Air and Inert Gas
- For Use With: Air, Inert Gas
- Temperature Range: 40° to 150° F
A lighter and more corrosion-resistant alternative to metal valves. All valves throttle a high vacuum source to maintain a lower vacuum level in your system. Adjust the outlet vacuum level within the range. Threads below the adjustment knob and an included panel-mount nut let you add these valves to your instrument panel. All are constant-bleed style, so they continually release small amounts of process gas to improve accuracy and repeatability.

Vacuum-Breaking Valves
Also known as vacuum breakers, these valves have vents that open when pressure drops to relieve vacuum conditions and prevent backward suction from drawing liquid into upstream piping.
Chrome-plated bronze valves are more corrosion resistant than brass valves.
303 stainless steel valves have the best corrosion resistance.
Elbows are designed for intermittent flow. They discharge liquid directly and should not be installed in areas where spillage could cause damage.
Straights are often used with steam coils, heat exchangers, and space heaters.

High-Pressure Vacuum-Breaking Valves
- For Use With: Air, Argon, Helium, Krypton, Neon, Oil, Water, Xenon
- Seal Material: Fluoroelastomer Rubber
Rated for 12 times the pressure of standard vacuum-breaking valves, these can handle up to 1,500 psi. Also known as vacuum breakers, they have vents that open when pressure drops to relieve vacuum conditions and prevent backward suction from drawing liquid into upstream piping. Body is 316 stainless steel for excellent corrosion resistance.

Vacuum-Breaking Valves with Garden-Hose Fittings
- For Use With: Air, Water
- Seal Material: Rubber
Prevent dirty, contaminated water from backing up into your garden hose line—install these valves between a faucet and a garden hose. Also known as vacuum breakers, these valves have a built-in check valve that blocks backflow, so you can leave your hose in a utility sink full of dirty water without the water going back into the line.
When the check valve is closed, it has vents that open to release the water. This reduces pressure in the line and confirms the valve is working. Because these valves vent water, use them in environments where spilled water won’t cause a problem. This design adheres to ASSE Standard 1011 for valves with a vent.
Mount valves to faucet outlets with a set screw, and easily thread or unthread a hose while the valves stay in place.
Valves comply with Uniform Plumbing Code (UPC) and are CSA certified, so they're safe to use in sanitary plumbing systems because they prevent contamination from flowing backward into your line.
These valves are designed to be used intermittently. They've been tested under ASME A112.1.3, which assumes the valves will not be used for more than 12 hours at a time.
Chrome-plated brass valves are more corrosion resistant than plain brass valves.
Valves with tamper-resistant set screws have a head that breaks off after tightening to prevent valve removal after installation.
Valves that meet NSF/ANSI Standard 372 are certified lead free.
