Straight-through cut-off valve, import and export of two channels in the same direction is 180 °, the cut-off valve, the flow state of damage is relatively small, therefore, through the pressure loss of the valve to the corresponding reduced.

Design features

►The product structure is compact and reasonable, the seal is reliable, the performance is good, the modelling is beautiful;
►The opening height is generally only a quarter of the valve seat, so the opening time is short;
►There is only a sealing cover on the valve body and disc, so the manufacturing process is good and easy to maintain.
►The valve has the design of reverse sealing structure to ensure that the stuffing box has no medium leakage and sealing performance
►Reliable, and can replace the packing online.
►The valve stem seals are used with flexible graphite and braided graphite, and the seal is more reliable.
