Rotork plc Reversing Relay M25

Description
Features Control Sensitivity of 1/8" water column. Balanced supply valve. Aspirator tube design. Separate control chamber isolates. Unit construction. Benefits Allows for use in high precision applications. Minimizes the effects of supply pressure variation. Compensates for output pressure droop under flow conditions. Isolates the diaphragm from the main flow to eliminate hunting and buzzing. Allows servicing without removal from air line. The Model 25 Reversing Relay is designed for applications requiring an output that equals a manually preset spring load minus a variable signal pressure. This high quality unit combines excellent sensitivity with unusually high flow capacity. The Model 25 is ideally suited for a variety of precision control applications, 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.
