GR400-15 pneumatic air pressure regulator
Technical Specifications

• Port Size: 1/2" PT / BSPP / NPT
• Pressure Regulating Range: 0.05 to 0.9 MPa (approx. 7 to 130 PSI)
• Maximum Supply Pressure: 1.0 MPa (145 PSI)
• Proof Pressure: 1.5 MPa (215 PSI)
• Operating Temperature: -20°C to 70°C (Non-freezing) 

Key Features

• Balanced Design: The pressure adjustment mechanism utilizes a balanced design to ensure minimal drift, high stability, and reliable pressure characteristics. 
• Self-Locking Mechanism: Features a press-in self-locking knob structure to prevent the set downstream pressure from being accidentally changed by outside vibration or interference.
• Space-Saving Gauge: Equipped with an embedded square pressure gauge to save physical installation space, though external round gauges are also optioned depending on the sub-model suffix. 
• Flexible Installation: Can be mounted directly onto a panel or set up via a fixed bracket. 

Are you looking for a solenoid valve to pair with this regulator (such as the standard AirTAC 4V410-15 1/2" valve), or do you need help finding replacements or data sheets for the GR400-15 regulator unit itself?
