Fairchild Model 25

Fairchild Model 25 Reversing Relays are designed for applications requiring an output that matches a manually preset spring load without a variable signal pressure. This quality unit combines precision sensitivity with high flow capacity. The Model 25 is suited for a number of precision control uses, including converting direct acting valves to reverse action, controlling opposite acting valves from a single transmitter, and cushioning cylinder loads. The basic mathematical expression for the Model 25 is PO = K - PS where PO is output pressure, PS is signal pressure and K is the spring constant.
