• Eco-friendly Hose Shank Outlet: For conveniently routing overflow away from critical components, reducing maintenance and promoting environmental responsibility.
• Maximum Pressure Endurance: Designed to withstand pressure fluctuations, functioning optimally between 7-21 psi.
• High Flow Capability: Effectively relieves up to 230 cubic feet per minute, safeguarding against pressure build-up.
• 1-1/4″ Inlet: Ensuring compatibility with a broad range of industrial equipment with its standardized inlet size.

RIV Pressure Valve: Superior Safety and Dependability

*Pressure relief valve will need to be adjusted in the field for your unique truck/tank specifications and application. We recommend 5 PSI maximum tank pressure.

Adopting the RIV 1-1/4” Pressure Relief Valve introduces a level of protection that transcends the average safety standards. The adjustable spring-loaded mechanism facilitates quick adjustments allowing for immediate response to changing conditions. A tamper-proof cap ensures settings remain unchanged, preventing accidental misconfigurations or deliberate meddling.

The marriage of a corrosion-resistant brass body with zinc-plated steel components means this valve is built to last. It will tirelessly combat the potential deterioration caused by the industrial environment. Specifically engineered to cater to high temperatures and pressures, this valve operates seamlessly within a wide performance window, ensuring your systems function safely and without interruption.

With the hose shank outlet feature, the valve not only protects your system but does so in a way that’s mindful of the environment, directing excess material safely away from the workspace. The maximum pressure tolerance offers a broad operational range, providing flexibility and peace of mind across various applications.

How it Works

The pressure relief valve sits quietly within your system, calibrated to a specific PSI above average operational levels. Should pressure exceed this threshold, the internal spring compresses, allowing the poppet to lift and open the valve. This action effectively discharges the excess pressure and brings the system back to equilibrium. Once the pressure normalizes, the spring returns the poppet to its seat, resealing the valve until it’s needed again.

With the RIV 1-1/4″ Pressure Relief Valve, you can be sure that your equipment will operate within its safe limits, averting potential disasters, and keeping your operations uninterrupted and your personnel safe. Equip your system with a valve that’s reliable, adjustable, and built to withstand the tests of time and nature.
