Quick Exhaust Valves With Silencer G 1/8 to G 1/2 and 1/8" to 1/2" NPT FESTD Type SEU-1/8 Type SEU-1/8-NPT Quick Exhaust Valve With Built-in Silencer Type SEU-... SEU-...-NPT e e b b Type SEU-1/2 Using this element, increased piston speeds can be attained in single-acting and double-acting cylinders. Compressed air flows from the control valve to the cylinder by path 1 to 2. Exhaust (3) is then closed. If the pressure at 1 decreases, 2 is exhausted to 3 through the built-in silencer. For effective performance, the quick exhaust valve must be mounted directly on the cylinder port. Noise level is reduced by the silencer.
