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.
