SPECIFICATIONS:
1.Pressure Reducing Valves automatically reduce a higher inlet pressure to a steady lower outlet pressure regardless of changing flow rate and/or varying inlet pressure.
2.Operates over a wide flow range.
3.Set pressure is adjustable via a single adjustment screw on thepressure reducing pilot valve.
4.Can be maintained without removal from the pipe line.
5.Flange to EN1092-2 PN10/PN16.
6.Adjustment range ofoutlet pressure: 4.5 to 11.4 bar(65 to 165 psi).
WORKING PRESSURE:
Maximum working pressure 16 bar (230psi).
STANDARD:
Product testing is carried out in accordance with GB/T13927 Industrial valve pressure test .
SET PRESSURE:
Factory pre-set outlet pressure to 10 bar (144psi).
TEMPERATURE RANGE:
0 °C to 80°C.
COATING:
Fusion Bonded Epoxy Coating.
