What it is
The Altecnic 2 1/2 F Non-Return Valve is a check valve from the Altecnic check valves range. It permits flow in one direction and closes against reverse flow, protecting the circuit from backflow and unwanted circulation. It is a 2 1/2 inch female connection valve.
Signs this part needs replacing
- Water or heating flow continues in the reverse direction when the pump stops.
- Gravity circulation or backflow through the valve seat, causing unwanted heat migration.
- Intermittent noise or chatter from the valve body under flow.
- Visible leakage or weeping from the valve body or connections.
- The valve fails to seat and hold against a head of pressure.
Before you order
- Confirm the pipework connection size and thread type match the 2 1/2 F connection on this valve.
- Check the flow direction arrow on the existing valve and the intended direction of flow in the circuit.
- Verify the valve body material and pressure/temperature suitability for the system it is being fitted to.
- Confirm the Altecnic check valve range is the correct fit for the installation.
