What it is
The Alpha 1.023587 is a 3/4 inch isolating valve with a lateral connection, used on Alpha gas boilers. It forms part of the boiler's pipework isolation arrangement, allowing the water circuit to be shut off for servicing or component replacement. It is listed for the Alpha Intec, Intec ErP and CD appliance families.
Signs this part needs replacing
- Water weeping from the valve spindle when the handle is turned
- The valve handle turns freely without shutting off the flow
- Visible corrosion or scale around the valve body
- Dripping from the valve connections or lateral joint
- The valve will not hold isolation during servicing, leaving the circuit live
Before you order
