49279 New Western Unimount Electric Solenoid Empty Valve Block 3500 PSI 49224

As of late 2025 Western has Discontinued this part # 

A New Western Valve Block # 49279.

This is just an empty valve block. It does not come with the valves themselves. This valve block is essentially the same as # 49224, the only difference being the pressure is set differently.

This is for the Isarmatic Relay plow pump used on Unimount straight blades. 

If you adjust the pressure it also has other parts #'s, this is the same as Fisher units as well. Here are other part #'s this would replace - 49278, 7623, 7921, 7922, 49279, 66259.
