Double Valves with Electro-Pneumatic E-P Monitor SERPAR® 35 Series

Double Valves with Electro-Pneumatic E-P Monitor SERPAR® 35 Series Product Overview

The SERPAR® Series valves are internally monitored double valves with a built-in monitoring device that checks for the proper operation of each valve element. If the internal monitor detects a valve fault on a particular cycle, the double valve will fail to a safe condition (all downstream air is exhausted) and the monitor will lock-out to inhibit further operation of the device. 

Normal operation can only be resumed by a momentary reset signal to the valve. Valve models with E-P monitor are available with Single Input Signal and Dual Input Signal. Single Input valves require only one main solenoid signal wired into the terminal strip of the E-P monitored double valve. The main solenoid signal is wired into terminal 1 and internally jumpered to the second main solenoid. Commons are wired into terminal 3. This allows both solenoids to be energized and de-energized simultaneously for proper valve operation.

Dual Input valves require two solenoid signals wired independently into the terminal strip of the E-P monitored double valve. One main solenoid signal is wired into terminal 1 and the second main solenoid signal is wired into terminal 5. Commons are wired into terminal 3.  Both solenoid signals must arrive simultaneously for proper valve operation.
