Features
- The R900 is a reduced bore version of the A900 automatic control valve main body
- The reduced bore design allows a smaller valve to handle a given line size, reducing weight, face-to-face length and installed cost while maintaining full hydraulic control authority
- Used with the standard P-series pilot range for pressure reducing, sustaining, level and flow control duties where space or weight constraints apply
Description
The R900 is a reduced bore version of the A900 automatic control valve main body. The reduced bore design allows a smaller valve to handle a given line size, reducing weight, face-to-face length and installed cost while maintaining full hydraulic control authority. Used with the standard P-series pilot range for pressure reducing, sustaining, level and flow control duties where space or weight constraints apply.
Selection notes
This control valve is supplied for flanged installation.
Sizes run DN80 to DN1000, in PN10, PN16, PN25.
The body is EN-GJS-500-7.
Seat and trim options are AISI 304 and AISI 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.
Working temperature is -10°C to 80°C.
Built to EN 1074-5, BS EN 1074-5, BS EN 558-1, ISO 5208 and BS EN 12266-1.
Supplier remarks
- Ordering code structure: R900-SSSS-PP-YYY (Model-Size-Pressure-Special), same pattern as the standard A900 family but with an R-prefix model code. PP = 10/16/25 for PN10/16/25, A1 for ANSI 125 F/F, A5 for ANSI 150 R/F.
