Air Preparation
The YT Series Filter Regulator share stable outlet pressure, 5-micron filtration, relief function, and manual/automatic drain options. Available in aluminum or stainless steel construction with 1/4" and 1/2" connections, the range offers compact and high-flow options.
Lock-up valve senses the main air-supply pressure. When the pressure falls below its set point, it shuts off airflow and traps pressure in the actuator, keeping the control valve approximately in its last position.
Volume booster relay is used in pneumatic control valve which receives the output pressure signal from positioner and supply air pressure to actuator to reduce opening and closing time of the valve.
