NRV Series Check Valve
Product Features
- Only allows air to flow in one direction and prevents backflow.
- Used to prevent backflow phenomena that can occur due to pressure drops in pneumatic circuits or a sudden drop in pressure from a large volume of compressed air.
- Large effective ventilation area.
- The internal part uses an imported POM valve core and an imported rubber sealing method, resulting in a simple and compact structure.
