The slab gate valve application and feature
This DBV slab gate valve has a novel structural design.Rigorous test, light operation, strong anti-corrosion, abrasion resistance and erosion resistance. It is an ideal new equipment in the petroleum industry.
The valve seat adopts o-ring sealing and pre-tightening force floating valve seat structure, so that the plate gate valve import and export two-way sealing; And the opening and closing torque of the structure is only 1/2 of the ordinary valve, which can easily open and close the valve.
The smooth, continuous bore minimizes turbulence within the valve and when in the open position it produces a pressure drop equivalent to a portion of pipe of the same length and diameter. The valve seat surface is located outside the fluid flow, thus avoiding the erosion effect of the fluid.
