* SB control valve is bronze, single seat, normally open, direct acting. KB51 and KC51 control valves are bronze, single seat, normally open, bellows balanced, direct acting. NS control valve is gunmetal, double seat, normally open, stainless steel trim, direct acting. A Y-type strainer 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.
