Rotork YTC Snap acting relay YT-520S21 YT-520S22 YT-520S23 YT-520S24
Snap Acting Relay is a device that receives its main pneumatic pressure from the plant as signal pressure and changes the direction of pneumatic flow by changing the direction of the flow path inside the product when the signal pressure drops below the set pressure. For general use, it is installed on the control valve, and when the main pneumatic pressure from the compressor is lower than the required pressure due to power failure or pipe breakage, it senses the drop and flows the pressure from the air tank which is connected to the Snap Acting Relay to the actuator of the control valve and moves the valve to the safe position.
