The slab gate valve is also called flat gate valve used of the floating valve seat and O-ring sealing, so that import and export of two-way valve seal plate; The headstock and the structure is only an ordinary valve torque 1/2, to achieve easily open the valve clearance. Plate valve for Class150-900/PN1.0-16.0MPa, work temperature -29-121 DEGREE C. Medium is oil, gas, water, oil and other medium, used for cut-off the media.

Slab gate valve is suitable for natural gas, petroleum, chemical industry, environmental protection, city pipeline, the gas pipeline conveying pipeline, such as steam vent system and the storage device, used for opening and closing device. Also it's suitable for natural gas exploration and purification of long distance pipeline.
Characteristics of flat gate valve:
1 Valve seat sealing structure shall be flexible with pretension, while sealing. It always seals face to face between valve seat and seal materials.
2 Valve seat with self-cleaning function, which directly in flushing opening or air flow is not affected by the closing process. Seat shall be lubricated, nor wear materials.
3 The faults in valve actuator will not affect other parts of the valve, and repair or replacement without removing the valve in the case.
(1) yoke sleeve: Aluminum Bronze yoke sleeve configuration needle thrust bearing, minimizes operating torque.
(2)the stem length of thread until the bracket; The pin and spot welding; Stability.
(3) the pressure seal: Has the advantages of simple structure, configuration of sub ring and silver plated low carbon steel washers, helps in removing and achieve the best bonnet seal.
(4) the seat ring: Welded seat rings are perpendicular to the flow channel, easy to maintain.
(5) implementing agencies: The valve can be electric, hydraulic or pneumatic actuator. DN300 the following configuration standards for hand wheel, DN350 above configuration helical gear operating mechanism.
(6) the yoke: Completely fabricated yoke by seismic testing, ease of maintenance and installation of the implementing agencies.
(7) gland: Two piece, self-adjusting gland, to avoid being ejected.
(8) integral backseat: Hard, the longest service life.
(9) the valve: The valve spring load to adjust, reduce actuator torque requirements.
(10) the overall stop: The whole cast bracket stop device, positioning the valve assembly of the bracket, making the seat more stable and reliable.
