Air-Release Valves for Water and Coolant
and Female
Outlet
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.
Valves with female/male inlets have an inlet with both male and female threads, so they can be connected to both male and female adapters and equipment ports.

Corrosion-Resistant Air-Release Valves for Water and Coolant
- Max. Pressure: 90 psi
- Temperature Range: See table
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.
Remote-Discharge Air-Release Valves for Water
- Max. Pressure: See table
- Temperature Range: 32° to 150° F
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.

Corrosion-Resistant Remote-Discharge Air-Release Valves for Water
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.

Air-Release Valves for Steam
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. They exhaust discharge directly through the vented relief port.

Motor-Driven On/Off Valves with Solder-Connect Fittings
- Valve Type: Ball
- For Use With: Water, Steam
- Seal Material : Buna-N Rubber
- Specifications Met: C-UL Listed, UL Listed
Slide copper pipe into the solder-connect fittings on these valves and weld for a strong, permanent connection. They’re often used for remote on/off control in heating and cooling systems. All operate on electricity to automatically start and stop flow. Valves do not require a minimum pressure drop between the inlet and the outlet for operation. They are normally closed unless actuated. All are standard port, so they slightly restrict flow.
The actuator is directly mounted to the valve body to minimize movement and reduce wear. The manual override allows you to operate the valve during power outages.
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.

Easy-to-Install Threaded Gradual On/Off Valves
- Valve Type: Gate
- For Use With: See table
- Packing Material: PTFE Plastic
A threaded union on these valves makes them easy to install and remove without disrupting your line. They thread together or apart with only a turn to the union fitting, unlike other threaded on/off valves that require repositioning your pipe or valve. The union fitting slides over your pipe, and the threaded fitting sits inside. They’re often connected to tanks in control rooms and to radiators. Also known as gate valves, they open and close gradually with multiple turns of the wheel handle to prevent sudden starts and stops. With a nonrising stem, the handle stays in the same place whether these valves are open or closed.
Brass valves have good corrosion resistance. They also have a more polished look than bronze valves.
Bronze valves resist corrosion better than brass valves, including from salt water. They’re also stronger.
