Features
- The A900 threaded is the small-diameter version of the A900 main valve body, with threaded BSP end connections for DN15 - DN50 installations
Description
The A900 threaded is the small-diameter version of the A900 main valve body, with threaded BSP end connections for DN15 - DN50 installations. Used with the same pilot family as the flanged A900, the threaded body provides pressure reducing, sustaining and level control functions in compact plant rooms, building services installations and irrigation systems where flanged connections are impractical.
Selection notes
This control valve is supplied for flanged installation.
Sizes run DN50 to DN1000, in PN10, PN16, PN25.
The body is EN-GJS-500-7.
Seat and trim options are AISI 304 and 316. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.
Stated service media include water.
It is catalogued for Water & Wastewater and HVAC.
Working temperature is -10°C to 80°C.
Built to BS EN 1074-5, BS EN 558-1, ISO 5208 and BS EN 12266-1.
