Discs and seats come in various materials to meet a wide range of needs.The ultimate general purpose valves with excellent costperformance.

  • Valve nominal size 40 to 600mm
  • Max. working pressure: 1.0MPa
  • Working temperature range:
    NBR: -10 to 80 degrees C
    EPDM: -20 to 120 degrees C

    Simple handling, durability, and long life are the most basic terms on whichvalves can be improved. TOMOE has now developed the700G series, a superior pressure-proof general purposevalve, to improve cost performance and meetmore

    Features

    N/A Satisfies ISO standards for face-to-face dimensions
    Valve face-to-face dimensions conform to standard ISO5752 (20series)
    Patented cosine curve seat ring
    The cosine curve seat ring reducesvalve operating torque substantiallyand allows the torque to be adjustedaccording to the working pressure.
    Much longer life with spherical design
    Similar to a spherical body rotating inside a spherical area, the operation of the disc is smooth and unhindered. Torque is reduced and the valve life is lengthened by 300%.
    Self-aligning stem seal through backup ring
    The stem seal is the primary and secondary seal system.The backup ring functions as the self-aligning stem seal.
    Select from various disc materials to meet your specific needs
    As one of the standard disc materials, PPS(for 50 to 200mm types)has been added to meet the current trend of linedpipes. PPS (polypheneylene sulfide with stainless steel core)is a kind of plastic material suitable for corrosive fluids(subject to the performance of rubber seats).
    Two aligning methods (350 to 600mm)
    Two valve models are available: the casted hole type (700G)and the tapped and drilled hole type (705G). They accommodate all the applicable flange standards.
    Long bonnet
    The long neck shape allows insulation of up to 50mm afterthe valve is installed.
