Bolt Flange Pressure Relief Valves Datasheets

Constant flow valves provide an accurate way of controlling flow without automation (neither electricity nor an air supply is required). Accurate control is achieved by the globe style body and seat-and-plug configuration. This unique design allows the valve to maintain a constant preset flow, even... [See More]

In the mid-1940s, a new relief valve actuated with a pilot rather than a spring set a new standard for pressure control. The valve, manufactured over the years by companies like Garrett, USI, Axelson, and NUFLO, is now manufactured and sold by Cameron's Measurement Systems division. The NuFlo... [See More]

Air Release Valves function to release air pockets that collect at each high point of a fully pressured pipeline. Air Release Valves can open against internal pressure, because the internal lever mechanism multiplies the float force to be greater than the internal pressure. This greater force opens...

The pressure reducing valves V782, V82 and V182 from GF Piping Systems reduce the pressure within the system to a pre-set value. By using the differential pressure, the pressure reducing valve adjusts itself to the set working pressure. The outlet pressure (working pressure) is not directly related... [See More]

Pilot operated pressure relief valves series R5V have a similar design to the subplate mounted R4V series. The SAE flanges allow to mount the valves directly on the outlet flanges of pumps or inlet flanges of actuators to achieve a very compact design. Valves with SAE flanges can also be bolted...
