Pneumatic Impulse Relays

Impulse relay valves allow you to shift a double-pressure piloted or double bleed piloted valve, even though there are overlapping pilot signals.  Relay valves convert a sustained air flow from a 3-way pilot valve into a momentary pulse or bleed, which shifts a control valve and then closes. Specifications and dimensions can be found online or in the Mead catalog.
