What it is
The Altecnic 1 F Single Check Valve DZR is a single (non-return) check valve from the Altecnic check valve range, built in dezincification-resistant brass. It is used in boiler and heating systems to allow flow in one direction only and prevent backflow through the pipework. The valve carries the 1 F size designation as stated in the product name.
Signs this part needs replacing
- Water passing the valve in the reverse direction when the system is not calling for flow
- Persistent circulation or heating when the pump is off, indicating the valve is not seating
- Visible leakage or weeping from the valve body or connections
- Corrosion or scale build-up on the valve body restricting the internal seat
- Noise or vibration at the valve position during pump operation
Before you order
- Confirm the pipework size and connection type against the 1 F designation in the product name
- Check the valve position in the circuit and that a single check valve is the correct type for that duty
- Inspect the surrounding pipework and connections for condition before fitting
- Note the product reference ALT-SCV025 for cross-checking against the existing valve
