NUFLO Relief Valves安全阀

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 pilot-operated pressure relief valve is an example of a tradition of advanced design and high-quality manufacturing abilities. These valves offer advantages not found in other relief valves - spring or pilot operated.

Valve Types

Type HF

This is a full lift, pop-action valve with a fixed (5% to 7%) blowdown using a single non-flowing pilot. This type of valve is designed for gas and/or vapor service and is offered in sizes of 1" through 8" with operating pressures ranging from 25 psig to 6000 psig.

Type HL

This is a modulating valve with a fixed (3% to 5%) blowdown using a single non-flowing pilot. This valve is designed for gas, vapor and/or liquid service and is offered in sizes of 1" through 8" with operating pressures ranging from 25 psig to 1500 psig.
