Stable structure: The pressure reducer has a 1/2" external thread, requires a 220V electrical connection, the maximum current allowed to work is 20A, the overall appearance is stable, performance are good, piston-type structure, wear-resistant and stable. Set parameters: The pressure regulator will automatically open at a specific pressure and automatically shut down under specific conditions. specific pressure switches, which is convenient and reliable, allowing you to use it confidently and convincingly. Efficient: The pressure switch is small in size, light in weight, easy to install and cost-effective , you can use this pressure reducer to meet your needs. Data representation: Applicable rated voltage of air compressor: 220/380V; Contact method: Normally closed; Pressure of Operation: 90-125 psi; Life: 80,000 times (ideal data) Function: If the work you are doing requires lower pressure, you can use this pressure regulator, the pressure regulator will reduce the steering pressure to the ideal level and it will always be constant.
