Motorized Carbon Steel LL Type Four Way Ball Valve

Motorized Carbon Steel LL Type Four Way Ball Valve

    The SV LL type four way ball valve is mainly used in bidirectional water supply system of power station to switch the mode of water supply by rotates the ball 90 degree.

    The SV T type three way ball valve can interlink all three channels. It is mainly use to achieve bypass flow, interflow and full open of three channels.

    The L type can only interlink the two channels which are mutually orthogonal. It is mainly used to change the flow direction.
