What it is
The Hamworthy 3/4 Pressure Relief Valve is a safety component used on Hamworthy boiler installations. It relieves excess system pressure by opening at its set pressure and discharging water away from the boiler circuit. This listing is for the valve as described by the manufacturer's part data.
Before you order
- Confirm the valve size stated on the existing component matches 3/4 before ordering.
- Check the Hamworthy boiler model and any parts list reference to confirm this valve is the correct item for the appliance.
- Verify the connection type and orientation on the existing valve against the replacement before removal.
- Check the system pressure and expansion arrangement as part of the same visit, since relief valve discharge often points to a separate fault.
