Kramer 3 Bar Safety Relief Valve 1/2 inch Male Thread, Brass – Compatible with Baxi 9950600, Protherm 0020027555, Ferroli 39800130, Sime 6040200, Immergas

The Kramer 3 bar safety relief valve is a safety component that opens and releases excess pressure when the pressure in the boiler heating circuit exceeds 3 bar. It has a brass body; the inlet is 1/2 inch male thread and the discharge outlet is 1/2 inch female thread. The arrow on the body shows the flow direction; the red knob is for manually testing the valve.

Which Boilers Does It Fit?

It is a compatible (equivalent) part used to replace the following original part codes:

Compare the part code of the old valve in your boiler, or the spare parts list of your boiler model, with these codes; check that the inlet thread is 1/2 inch male.

When Should the Safety Valve Be Replaced?

• If water keeps dripping from the valve even though the system pressure is normal (1–2 bar).
• If the boiler pressure drops frequently and no leak can be found elsewhere.
• If the valve is scaled and does not close fully when the test knob is turned.

If the valve discharges water because the pressure rises above 3 bar, the problem is not the valve but the system pressure or the expansion vessel; check the pressure and the vessel first.

When Replacing

• Switch off the boiler, let it cool down and reduce the system pressure to zero.
• Remove the discharge hose and unscrew the old valve; apply sealant to the thread.
• Fit the new valve with the arrow pointing in the flow direction and connect the discharge hose.
• Refill the system to 1–1.5 bar and check the connections for leaks.
