Float Valve | Equilibrium Ball Float Valves

PRESSURE/ TEMPERATURE RATING OF FLOAT VALVE:

50-300mm  TEMP. (Max Inlet Water Feed)

10 Bar          23°C

FLANGED: BS 10 Table F

DRILLED:

• BSEN 1092-2 – PN10, PN16
• BS 10 Tables – D, E, F

ANSI B 16.1-Class 125

• Bolted cover plate to protect seal and cylinder of float valve from the ingress of debris.
• Maintenance is simplified by easily replaceable piston and steel reinforced renewable rubber disc.
• Adjustable float for optimum water level control.
• The valves are supplied with the line flanges to BST ‘F’ diameter. Unless otherwise instructed the inlet flange will be drilled to match the flange specified on order. The outlet flange will not be drilled unless ordered.

MATERIALS:

• Body/Cover – Cast Iron to Cover BS EN 1561 EN GJL 250
• Seat Ring/Cylinder- Gunmetal to Valve Seat BS EN 1982 CC491K
• Disc – EPDM Rubber bonded to steel reinforcing plate
• Piston Seal – EPDM Rubber
• Float – Tough Rilsan nylon coating heat-fused to steel

Note: Dimension ‘D’ conforms to WRAS requirements for minimum height above water level  type ‘AA’ air gap. Due to HIGH LEVEL RATIOS, dimension ‘D’ is subject to tolerance of +/-10%. It is recommended that the flow velocity should not exceed 3m/s (10f/s) giving a max flow of J litres/sec, K gall/min.
