Product Features
The sealing structure of the valve seat should be elastic with preload, and the upper and downstream sealing seats should seal simultaneously. There is always a face-to-face seal between the valve seat and the seal.
2. The valve seat has a self-cleaning function and is not directly washed by the airflow during the opening or closing of the valve. The valve seat should be made of lubricating and non-abrasive 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 removing the valve.
(1) Yoke sleeve - The aluminum bronze yoke sleeve is equipped with needle-shaped thrust bearings to minimize operating torque to the greatest extent.
(2) Valve stem - Thread length up to the bracket; Pins and spot welding It has stability.
(3) Pressure seal - Simple structure, equipped with segmented retaining rings and silver-plated low-carbon steel gaskets, which facilitate disassembly and achieve the best valve cap seal.
(4) Valve seat ring - The welded valve seat ring is perpendicular to the flow channel, which is easy to maintain.
(5) Actuator - These valves can be equipped with electric, hydraulic or pneumatic actuators. For DN300 and below, standard manual handwheels are configured; for DN350 and above, helical gear operating mechanisms are provided.
(6) Yoke - The fully assembled yoke has passed the seismic test and is easy to maintain and install the actuator.
(7) Cover - Two-piece type, self-adjusting cover to prevent it from being ejected.
(8) Integral rear seat - hard surface, longest service life.
(9) Valve disc - The spring-loaded valve disc can adjust itself, reducing the torque demand of the actuator.
(10) Integral stop - The integral cast bracket stop device, with the positioned and assembled bracket valve disc, makes the valve seat more stable and reliable.
The Z43WF flat gate valve with flow guide holes is suitable for natural gas, petroleum, chemical, environmental protection, urban pipelines, gas pipelines and other transportation pipelines, venting systems and steam storage devices, and is used as an opening and closing device. Long-distance pipelines suitable for natural gas extraction and purification.
