Check Valves For HJ 250 | 4350psi Pump
On a Triplex Pump there are six (6) Check Valves.
3 Inlet Valves on the lower side and 3 Outlet Valves on the upper side.
These Check Valves are fitted into the manifold onto the 'O' Ring Seat, and are easy to install.
Check Valve Outer Diameter = 20mm
Check Valve Height = 17.5mm
Heat build up can deform the Check Valve Housing, consequently you will suffer a vast decrease in pressure.
If your pump doesn't have a Thermal Relief Valve (Dump Valve)- look at installing one. This will help protect the Check Valves by releasing over-heated water and and allowing fresh water in.
