Pressure Relief or Sustaining Valve

Size (mm) : 50-1000
Pressure rating : 6-40 (bar)
Body Material: All Types of Ductile Cast Iron, Cast Steel, Stainless Steel, Copper Alloys
Disc Material: All Types of Ductile Cast Iron, Cast Steel, Stainless Steel, Copper Alloys

Automatic control valves are designed to regulate and control the fluid flow and pressure. The body style is either horizontal or diagonal shape, with the internal configuration suitable for fluid flow. The valve is controlled automatically by a pilot valve and water flow. Automatic control valves do not require an external power source, meaning that the fluid pressure is enough for opening and closing the valve.

Paint Coating :
Electrostatic epoxy powder (RAL 5005 or 5015) with min. thickness 250 micron.

Application :
Usable for drinking water and raw water with temperature up to 70°C.
This type of Automatic control valve (type 116) is able of adjust the inlet pressure, control the network pressure and if necessary discharge the excessive pressure through by-pass line.
There will be variety of functions Depend on valve installation location in the pipeline:
• Valve installation in main pipeline: Keeping upstream pressure on desired value. (Pressure sustaining valve)
• Valve installation in by-pass line: discharging the excessive pressure (Pressure relief valve)
• Valve installation after pumps
