Overview
Flat gate valve with diversion hole
Product Details
With a guide plate gate valve has reliable sealing performance, opening and closing torque is small, with anti sulfur resistance, long service life, can pass the ball clean wool pipeline etc; opening and closing device for piping system for water, oil, natural gas, steam and other non corrosive and corrosive medium, especially suitable for petrochemical, oil gas pipelines and other fields.
The seat is sealed by O ring and preload floating seat structure, so that import and export of two-way valve seal; and the structure of the normal valve opening and closing torque only 1/2, can easily open and close valves.
The valve seat sealing surface inlaid with PTFE, with PTFE on metal and metal to metal double seal, PTFE sealing surface dirt while the role of gate clearance.
The metal to metal seal, there is grease injector outside, grease through the grease device, the valve seat into the valve sealing surface of the valve to achieve zero leakage.
The gate valve with diversion hole, either fully open or fully closed always coincide with the sealing surface, sealing surface to be protected from direct scouring medium, thus prolonging the service life.
he valve in the fully open, the channel smooth straight line, flow resistance coefficient is extremely small, no pressure loss, can pass the ball clean wool pipeline.
- the packing structure with the ability of self sealing, without frequent adjustment, opening and closing very lightweight, and reliable seal, the stuffing box is arranged at the auxiliary seal oil into the structure, absolutely reliable sealing performance, thereby achieving zero leakage; solve the shortcomings of the general valve packing leakage of the most vulnerable.
The valve closes automatically remove the cavity pressure (see principle diagram), to ensure safety.
Fully sealed structure, good protective performance, can adapt to all-weather requirements. No Information
