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.

Key-Operated Air-Release Valves for Water
- Max. Pressure: 150 psi
- Temperature Range: 33° to 200° F
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.
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.
