Unlike valves that release discharge directly, these have a threaded relief port to direct discharge away from your work environment. Often used to increase pump efficiency, they eliminate air pockets in your system to maintain consistent flow and prevent water surges that can damage equipment. All have a cast iron body to absorb vibration for reduced noise and wear in your pipeline.

For excellent corrosion resistance in wet conditions and harsh environments, these valves have no metal parts. They eliminate air pockets to maintain consistent flow and prevent water surges that can damage equipment. All have a threaded relief port that can be attached to a drain line for remote discharge.

These valves are often used to remove air pockets in cooling and heating systems to maintain consistent flow and prevent water surges that can damage equipment. All have a vented relief port to exhaust discharge directly.
These valves are made of corrosion-resistant materials for use in wet conditions and harsh environments. They eliminate air pockets to maintain consistent flow and prevent water surges that can damage equipment. All have a vented relief port to exhaust discharge directly.
Valve with a Buna-N seal is for use in heating and cooling systems.
Valve with an EPDM seal is for use in cooling systems only.
Turn the key to manually release air from radiators, heaters, and other hot water equipment. These valves have a vented relief port that exhausts discharge directly. Body is nickel-plated brass for good corrosion resistance.
Eliminate air pockets without stopping flow—these valves have an internal wire brush that traps air bubbles and discharges them through the top relief port while allowing inline flow from the inlet to the outlet. They are often used to increase efficiency in heating and cooling systems. The vented relief port exhausts discharge directly. Valves have a durable bronze body for a long service life.
Eliminate air pockets in your drinking water system with these valves. They meet NSF/ANSI 61, which designates them as safe to use with drinking water. They have a vented relief port to exhaust discharge directly.
Our only air-release valves for steam, these seal shut when steam enters the valve to prevent system contents from escaping through the relief port. They are commonly used to eliminate air pockets in steam mains and risers. All exhaust discharge directly through the vented relief port.
Use this valve to eliminate air pockets in systems for oil, diesel fuel, gasoline, and kerosene. Valve has a vented relief port to exhaust discharge directly. Body is 304 stainless steel for excellent corrosion resistance.
