PRESSURE RELIEF VALVE BAYARD

PRESSURE RELIEF VALVE BAYARD Control valve enabling reduction and Stabilisation of the downstream pressure, by either sustaining or relieving excess pressure to the downstream side.

DESCRIPTION PRESSURE RELIEF VALVE BAYARD:

• For general information concerning the operation of a hydrobloc control valve, please consult our general manual ( series K ).
• Extensive range including two different designs:
  • XG Design:
    • Large flow capacity
    • Low head loss
    • Watertight T zero flow rate
    • XGS Design
      • Particularly suitable for pressure reduction,
      • Better cavitation resistance,
      • Watertight at zero flow rate,
    • CONSTRUCTION :
      • Self-lubricated double guided mobile unit,
        • Ductile iron body and design,
        • Stainless steel seat for standard version until DN 400 XG design and DN 600 XGS design,
        • Powder epoxy coating,
        • Stainless steel bolting,
        • Stainless steel pilot circuit tube and fittings,
        • Pilot circuit strainer with screen in stainless steel,
        • Individually packed.
    • EASYY OPERATION AND MAINTENANCE
      • Visual position indicator with manual drain
      • Including isolating valve ( s )for pressure gauges,
      • Equipped with opening speed controller “RO” 9 DN50 to 300 XG design, and DNI150 to 400 XGS design only )
      • Chamber isolating valve independent from the adjustment of the speed controller,
      • Maintenance without disassembly from the pipeline.
      • Easy dismantling from the top.
      • Drain plug ( stainless steel )
• Product according to standard EN 1074-5

  series 1 ( Expect DN1000 )
• Flange drilling according to standard EN 1092-2 and ISO 7005-2 : ISO PN 10, 16 or 25 for DN50 to
  1000 ( other drillings, please consult us ).
• Fluid drinking water or 2 mm filtered untreated water.
• Working pressure 25 Bar.
• Vertical & Horizontal intallation.
• The valve body of PN 16 and PN25 are the same, the diffference are on flange drlling and plot circuit.

FUNCTIONS :

• Reduces and stabilises a higher inlet pressure to a steady lower downstream pressure regardless of variations of flow and/or inlet pressure.
• Close/ open and puts into regulation with hand

APPLICATIONS :

• To regulate multi pressure level network.
• To supply water to a flow pressure level network from a high pressure level network.
• To protect a device, private consumers installations, or sections of the network against excessive pressure and high upstream pressure variations,
• To reduce leakage thanks to the control of the supplying pressure,
• To save water consumption by a reduction in pressure, etc….
