Spirax Sarco SRV66 Sanitary Pressure Reducing Valve for Clean Steam Systems
SRV66 is a self-draining 316L sanitary pressure reducing valve for clean steam, water and inert gas duties where hygienic pipework needs local downstream pressure control without an external sensing line.
Quick facts
Where SRV66 is typically installed
SRV66 is most useful where a hygienic process benefits from higher-pressure distribution upstream but lower and more stable pressure at the equipment connection. Typical examples include sterilising equipment, process vessels, humidifiers and other clean steam users that do not need main-line pressure at the point of use.
Pressure station considerations
Installation guidance recommends treating SRV66 as part of a complete pressure reduction station. That usually means clean upstream separation and filtration, downstream overpressure protection where required, and separate isolation valves because the reducing valve is not intended to serve as the shut-off device.
That wider station logic is important on clean steam lines because pressure reduction affects not only process setpoint accuracy but also steam quality, condensate behaviour and the protection limits of downstream hygienic equipment.

- Compare with STERI-TROL clean service control valves when the duty depends on pneumatic modulation rather than self-acting reduction alone.

Coordinate pressure reduction with relief protection
Use clean service safety valves when downstream pressure reduction also needs dedicated overpressure protection.
Separate pressure reduction from process control
Move into clean service control valves when the duty depends on modulating flow control rather than self-acting pressure reduction alone.
