The Ruelco quick exhaust is designed to rapidly bleed the control pressure from an actuator or other pneumatic or hydraulic device. It is typically used on safety valves, control valves, or other devices that must respond quickly when the control signals are removed. Its in-line design and three part construction make the quick exhaust easy to install and maintain. No special tools are needed for repair and assembly. The Ruelco quick exhausts will improve equipment operation and reduce maintenance time.
