O fixed ball valve adopts fixed ball design, relative motion parts adopt minimum friction coefficient self-lubrication material, and operating torque is small, moreover sealing grease seal for a long time, make the operation more flexible.

The characteristics.
    1, metal hard seal O fixed ball valve structure of metal movable sealing in both directions, with automatic compensation function, sealed performance is superior.
    2, O fixed ball valve adopts fixed ball design, and increases the pre-tightening force of spring, make the ball valve with functions of automatic pressure release.
    3, each ball valve has two movable sealing seat, both directions can be sealed, and install need not consider the flow of medium.
    4, with fire retardant anti-static structure, in the stem and valve body and valve stem and ball set between the conductive spring, avoid static spark ignited flammable medium.Ensure the security of the system.
    5 double protection, the structure of the refractory, but one thousand fire and make the seal when burning, any part of the ball valve can form the metal to metal hard seal structure.

    6, automatic pressure relief structure, when the liquid medium entrapped in the valve lumen due to temperature gasification, and lumen abnormal pressure rises, the midplane medium can rely on itself thrust to push the seat and automatic relief, to ensure the safety valve.

role

    O type ball valve: can be adjusted up and cut off action, often used in the two type of control.It simple flow, wide open fully formed straight channel, the minimum pressure loss, especially suitable for high viscosity, suspension occasions, such as pulp fluid.Reliable sealing, leakage is very small, soft sealing ball valves can reach a level bubble.
