Where steam supply pressures are higher consider the use of a pressure reducing valve or alternatively, the use of a combined pressure reducing and temperature control valve. Please consult Spirax Sarco for a suitable type.

* BX6 and SB control valves are bronze, single seat, normally open, direct acting. A Y-type stainer is recommended upstream of the control valve. The Y-type strainer should normally be the same size as the steam
supply pipeline. Consider a Spirax Sarco brass/bronze Fig 12 strainer. An isolating valve is recommended upstream of the Y-type strainer. Consider the use of an M10 Spirax Sarco carbon steel ball valve or a HV3 bronze stop valve.
