Complete Description

The GENERANT VRV-375B-B-015 is a compact, high-accuracy, direct-acting vent relief valve designed to provide dependable overpressure protection in compatible pressure and gas systems.

This configuration features a 3/8″ NPT connection, brass valve body, and Buna-N sealing element, and is factory preset to relieve at a nominal 15 PSIG. The VRV design vents excess pressure directly to atmosphere rather than routing the discharge through an inline outlet.

Generant’s VRV series incorporates an internally adjusted, tamper-resistant design and a Quad-ring seal intended to provide accurate, repeatable cracking and a narrow reseat band. The manufacturer specifies a ±5% set-pressure tolerance for valves set between 2 and 150 PSIG and approximately 92% reseat performance for units set between 10 and 150 PSIG.

The Buna-N seal used in this model has a manufacturer-specified temperature range of approximately -40°F to 250°F (-40°C to 121°C). Actual suitability depends on the media, temperature, pressure, installation, and material compatibility of the system.

Typical Applications

Suitable, when materials and ratings are compatible, for:

  • Industrial compressed-gas systems
  • Pressure regulation and protection assemblies
  • Gas distribution equipment
  • Pneumatic systems
  • Process equipment
  • Pressure vessels and related piping
  • Industrial and laboratory gas installations
  • General pressure-relief applications requiring a 15 PSIG preset valve

Generant states that the VRV family is intended for system overpressure protection and can be configured for various industrial and gas applications; proper seal and material compatibility must be confirmed for the specific medium.
