Slab Gate valve
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.
Pressure: 150LB-2500LB
Size: DN15-DN1200
Design Std: API, DIN, BS, GB, JIS
Product Material: CAST-IRON, ASTM A216 WCB, A351 CF8, A351 CF8M, A105, A410
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.

Main Feature
Urgent grease injection device
According to customer s' requirement, the trunnion ball valves made by our company are provided with devices for urgent grease injection, which are on both the stem and seat for the trunnion ball valves of DN >150mm (NPS), and in the body cavity for the valve of DN < 125mm. When the O ring of stem or the body seat ring is damaged due to accident, the medium leakage between body and stem can be prevented by injecting the sealing grease through the device.
Double-block and bleed functions
In general, our company's trunnion ball valve features the front ball sealing design structure. Each seat of the ball valve can separately cut off the medium at both inlet and outlet of the valve to realize double-block functions. When the ball valve is closed, body cavity and two of the body ends can be blocked with each other even if both the inlet and outlet are under pressure, when the medium left in the body cavity might be bled through the relief valve.
Fire safe design
With the valve heated in a fire application, the non-metal material parts such as seat sealing ring of PTFE, O ring for the stem, and sealing gasket for body and bonnet, might be damaged due to high temperature. Our company's special design of auxiliary metal to metal or the graphite seal is provited fo rthe trunnion ball valve to effectively prevent both internal and external leakage of the valve. As required by customers, our company's fire safe design for the trunnion ball valve meets the requirement of API 607, API 6Fa, BS 6755 and JB/T 6899.
Self-relief in the body cavity
As the liquid medium left in the body cavity gasifies due to increased temperature, the pressure in the body cavity becomes abnormally higher, when the medium itself in the cavity would propel the seat and self-relieves the pressure to ensure the safety of valve.
