Extended-Life Vacuum-Regulating Valves for Air and Inert Gas
 |
For a longer service life than brass vacuum-regulating valves, these are made of bronze for strength and durability. They throttle a high vacuum source to maintain a lower vacuum level in your system. Turning the adjustment screw will adjust the vacuum setting.

Adjustable Vacuum-Relief Valves for Air and Inert Gas
 |
These valves begin opening at the set vacuum level and fully open at about 10% over the set point. They begin closing as the vacuum level drops and fully close when the system is restored below the set point. Adjust the set vacuum level within the range. Valves have a vented relief port to exhaust discharge directly.

High-Accuracy Panel-Mount Vacuum-Regulating Valves for Air and Inert Gas
 |
For precise control over your vacuum level, these valves have ±0.1% accuracy. They throttle a high vacuum source to maintain a lower vacuum level in your system. Adjust the outlet vacuum level within the range. Valves have threads below the adjustment knob and come with a panel-mount nut. All have a gauge port. They are constant-bleed style, so they continually release small amounts of process gas to improve accuracy and repeatability.

Vacuum Breakers
90° Elbow
 |
Elbows are designed for intermittent flow. They discharge liquid directly and should not be installed in areas where spillage could cause damage.

Vacuum Breakers with Garden-Hose Fittings
 |
Set Screw |
 |
Tamper-Resistant Set Screw |
Prevent dirty, contaminated water from backing up into your garden hose line—install these vacuum breakers between a faucet and a garden hose. Also known as vacuum-breaking valves, 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.
Tamper-Resistant Set Screw—Valves with tamper-resistant set screws have a head that breaks off after tightening to prevent valve removal after installation.
NSF/ANSI 372—Valves that meet NSF/ANSI Standard 372 are certified lead free.
Chrome-Plated Brass Body—Chrome-plated brass valves are more corrosion resistant than plain brass valves.
