GR Series Regulator
Embedded Gauge | Balanced Design | Self-locking Mechanism
Product Features
- Embedded Gauge: Features an innovative embedded square pressure gauge design that significantly saves installation space and prevents physical damage. (An external round gauge is also available as an option). The scale is clear and easy to read.
- Self-locking Mechanism: Equipped with a reliable press-in self-locking knob that prevents accidental or vibration-induced changes to the pressure setting.
- Balanced Design: The internal pressure adjustment mechanism adopts a balanced design, ensuring highly stable pressure regulation, minimal drift, and excellent flow characteristics.
- Flexible Installation: Can be conveniently installed directly on a panel or surface-mounted using the optional fixing bracket.
- Low Pressure Option: In addition to the standard model, a dedicated low-pressure type is available (Max. adjustable pressure 0.4 MPa) for sensitive pneumatic applications.
