Clippard Modular 4-Way Delay Valve R-453

The R-453 is a 4-way, spring-return, fully ported 5-port delay valve with an adjustable flow control interconnected to the pilot. A pilot signal at port 4 is delayed before actuating the valve, and a spring returns the valve when the pilot signal is exhausted. It features a screwdriver slot needle adjustment to deter tampering and an auxiliary pilot on the spring side. It provides 9 scfm flow at 100 psig, operates within 0 to 150 psig working pressure and 32 to 180°F temperature range, with a minimum pilot pressure of 40 psig. Micro gap construction ensures snap action and no blow-by.
