Description:The pressure relay can be used in pneumatic, hydraulic and oil system. In the process of operation, the pressure relay can provide an electrical signal to regulate the working condition when sense pressure rises above or falls below the selected setting.Features:The pressure relay can be used in pneumatic, hydraulic and oil system.The scales are marked clearly on the surface, very convenient and precise to control.PT1/4 inch thread is suitable for most machine, easy to install.The special structure about flow channel of valve body can reduce the internal pressure loss, which improves energy efficiency.Reduce the oil temperature and increase life expectancy, save maintenance costs because of the small impedance.Specifications:Type: Straight through Voltage: AC 250VCurrent: 3AWorking temperature: 60Installation: Tube typeConnecting thread: PT1/4"Rated pressure: 30-210kg/cmMax pressure: 210kg/cmSize: Approx. 13.5 x 8.2cm / 5.31 x 3.23inchWeight: Approx. 999gPackage Included:1 x Pressure Relay
