Materials: Body “DR” Brass to AS1567 alloy 352. Sealing O’Rings - Nitrile, potable water approved to AS4020 or EPDM or Viton if applicable
Construction: Valve assemblies comply to Australian Technical Standards ATS5200-037.1.
Flange Specification: Suits standard table “D” flanges to AS2129 and AS4087 Class 14. Alternative specs are available - Refer to Valve Selection Guide for additional info. Standard Wafers are not full flange type i.e. flange bolts locate wafer concentrically and remain visible when viewing assembly. Wafers are fitted with an O-ring in each face for sealing against smooth flat faced flanges. Gaskets will however be required where grooved, raised or rough cast face flanges are used. PVC and Poly Stub Flanges note; Due to smaller I.D. of these flanges/pipes, optional spacers are often required to prevent restriction.
Max Pressure Differential: 1500 kPa (for N6 and EP rubbers only)
Max Hydrostatic Pressure: 6000 kPa
Max Temperature: 60C for Nitrile control rubbers, 100oC for EPDM
Compatible Control Rubbers: Standard Precision P (Non Standard LP, N6, EP, K, V, HF)
