Product Usage
Flat gate valves are suitable for natural gas, petroleum, chemical, environmental protection, urban pipelines, gas pipelines and other transportation pipelines, venting systems and gas storage devices, as opening and closing equipment. Long distance pipelines suitable for natural gas extraction and purification.
Applicable Standards
1 Design & Manufacture Conform with: API 6D/ ISO 14313, ASME B16.34
Characteristics of flat gate valve
The sealing structure of the valve seat should be elastic with pre tightening force, and the upstream and downstream sealing seats should be sealed simultaneously. The valve seat and seal are always sealed face-to-face.
2. The valve seat has a self-cleaning function and is not directly flushed by the airflow during the valve opening or closing process. The valve seat should be made of lubricated and wear-resistant materials.
3. The malfunction of the valve actuator will not affect other parts of the valve, and maintenance and replacement work can be carried out without disassembling the valve.
(1) Yoke sleeve - Aluminum bronze yoke sleeve is equipped with needle shaped thrust bearings to minimize operating torque.
(2) Valve stem - thread length up to the bracket; Pin and spot welding; Has stability.
(3) Pressure seal - simple structure, equipped with segmented retaining rings and silver plated low-carbon steel gaskets, helps to disassemble and achieve the best valve cap seal.
(4) Seat ring - Welded seat ring perpendicular to the flow channel, easy to maintain.
(5) Execution mechanism - These valves can be equipped with electric, hydraulic, or pneumatic actuators. Manual handwheel with standard configuration below DN300, and helical gear operating mechanism with configuration above DN350.
(6) Yoke - The fully assembled yoke has passed seismic testing and is easy to maintain and install the actuator.
(7) Cap - two-piece, self-adjusting cap to prevent it from popping out.
(8) Overall rear seat - hard surface, with the longest service life.
(9) Valve disc - Spring loaded valve disc can adjust itself, reducing the torque demand of the actuator.
(10) Integral Stop - The integral casting bracket stop device positions the assembled bracket valve disc, making the valve seat more stable and reliable.
