The 1000 Series is a globe valve considered a high quality valve providing excellent sensibility, fine control and easy adjustment, with very reduced weight and size.
The 6A Air Vent has both a float and a thermostatic bellows for use where air, condensate and steam may be present (as in one pipe steam heating systems.) The 6A will discharge air, while preventing the escape of either condensate or steam. An outlet check valve prevents the re-entry of air.
These instructions relate to the use of the DP143 (Section 2.1) and DP163 (Section 2.2) pilot operated pressure reducing valves on steam applications but can be used as a guide when the valve is used on compressed air applications. The DP143G and DP163G are recommended for compressed air applications, both having a nitrile seal for the main valve and pilot valve assemblies.
LSB limit switch boxes are normally used for indicating valve open or valve closed position. They also allow switching points to be adjustable over the full range of actuators. There is an open/ closed valve position indicator mounted at the end of the switch box axis, at the top of the cover. LSB's include a stainless steel linkage kit for direct mounting to BVA300 series actuators.
Spirax Sarco Float & Thermostatic Steam Traps are ideally suited for most HVAC and process applications. The spherical stainless steel float automatically adjusts the position of the main valve so that condensate is discharged continuously at the same rate as it enters the trap.
This guide covers only a brief description of installation and maintenance for Spiratrol and QL valves.
The Stonel Limit Switch is for use with the K Series pneumatic control valves and PN5000/6000 actuators. It is mounted on the PN5000/6000 actuators and can provide visual indication if the valve is fully open, fully closed, partially open (0-100%) or partially closed (0-100%).
AEL7 series electric linear actuators are only suitable for the use on Spirax Sarco, Gestra and Hiter Valves.
The USTS Steam Trap Station is designed to have inlet and outlet isolation valves, integral strainer with blowdown and test valve. Designed as a complete steam main drip or tracer steam trap station, the USTS will support all of the Spirax Sarco universal steam traps.
Pipeline connectors PC3000, PC3001 and PC4000, PC4001 have integral piston valves. A leaktight seal in the piston valve is obtained by a piston, operated by a handwheel and a threaded spindle, moving through two sealing rings separated by a lantern bush.
