Pressure reducing valve upgraded
February 1st 2005

Spriax Sarco pilot operated pressure reducing valves have been upgraded with the introduction of a hi-tech, variable rate, pressure control spring, simplifying ordering and cutting spares stockholding costs. Just one version of the DP17 valve covers downstream operating pressures from 0.2 to 17 bar g, rather than the three variants previously required.

Fewer options eliminates the risk of the wrong valve being specified and a valve can now be changed to an application with a different pressure requirement without the cost of changing the control spring.

The DP17 is suitable for use with steam, compressed air and other industrial gases, has a maximum operating temperature of 232°C and is available from DN15 to DN50.

The valve balances downstream pressure against the control spring, which then modulates the main valve via a small pilot valve.

With no external power source needed, the valve has low operating costs.
