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.
