SRV66 卫生型减压阀

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.

• Review SVL488 clean service safety valves when hygienic overpressure protection is also required downstream.
• Compare with STERI-TROL clean service control valves when the duty depends on pneumatic modulation rather than self-acting reduction alone.
• Browse the wider clean steam range to connect pressure reduction with separators, filters and hygienic shut-off valves.
