Overview
The Generant VRV-125A-V-5 is a compact, direct-acting vent relief valve with a factory preset crack pressure of 5 PSIG. This valve is designed for precise, tamper-proof performance with a Quad ring seal for extreme accuracy and repeatability, with a narrow reseat band. The VRV series is widely used in pneumatics, low-pressure hydraulics, and venting applications where controlled pressure relief is critical to system safety and performance.
Key Features
- Direct-acting design factory preset to your specified crack pressure
- Quad ring seal for extreme accuracy and repeatability with a narrow reseat band
- Zero leakage to 95–98% of set pressure with +/– 5% set pressure tolerance
- Viton seals for extended temperature range operation
- Tamper-proof internal adjustment prevents inadvertent pressure changes
- Vent-to-atmosphere configuration available in brass, aluminum, or 316 stainless steel
Technical Specifications
The following specifications apply to the VRV-125A-V-5:
- Set Pressure: 5 PSIG (0.34 bar)
- Seal Material: Viton (standard for VRV-125A-V)
- Temperature Range: –10°F to 375°F (–23°C to 190°C)
- Valve Type: Vent-to-atmosphere, direct-acting relief
- Cracking Pressure Tolerance: +/– 10% for set pressures below 2 PSIG
- Reseat Performance: 80% of set pressure for 2–10 PSIG valves
- Materials: Brass body with internal adjustment
Typical Applications
The VRV series is designed for compact, high-accuracy, internally adjusted, direct-acting pressure relief applications in:
- Pneumatic system venting and pressure control
- Low-pressure hydraulic pump relief and protection
- Air compressor and tank venting
- Nitrogen and inert gas systems
- Water and fluid transfer systems
- Oxygen-service applications (when cleaned per specification)
Compatibility & Replacements
Compatible With
- Pneumatic and low-pressure hydraulic systems (0.5–10 PSIG)
- Pump discharge piping with 1/8″ to 1/4″ NPT ports
- Modular pressure control manifolds and subplates
- Custom relief valve cartridge systems
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The VRV-125A-V-5 replaces equivalent Generant VRV models with identical port size, pressure rating, and seal material. Cross-references to competitor models (e.g., Hydac, Eaton, Parker) require pressure rating and port configuration confirmation.
Works With
- NPT, SAE, and BSPT thread configurations (verify specific model)
- Vent-to-atmosphere exhaust lines and mufflers
- Standard gauge ports for pressure monitoring
- Pilot-operated relief and flow control subsystems
