Description of flat gate valve
Model: Z43F/Y with diversion hole, Z43WF without diversion hole
Structure: flat sliding valve
Material: carbon steel, stainless steel
Flink Flat Gate Valve is a sliding valve with parallel gates as the closing part. The closing member can be a single gate or a double gate with a spreading mechanism in between. The pressing force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or the floating valve seat. If it is a double gate flat gate valve, the expansion mechanism between the two gates can supplement this pressing force.
Structural features
The flat gate valve has reasonable structure, reliable sealing and easy operation. The sealing surfaces are all spray-welded hard high-pressure plate gate valve alloy with diversion holes, which has the advantages of corrosion resistance, wear resistance, erosion resistance, etc., and can be used for throttling. Especially suitable for water, oil, mud and natural gas pipelines with working pressure≤42MPa and working temperature≤120ºC as opening and closing and regulating devices for controlling the flow of medium. It is suitable for natural gas, petroleum, chemical, environmental protection, urban pipelines, gas pipelines and other transportation pipelines, venting systems and steam storage devices, as opening and closing equipment. Suitable for long-distance pipelines for natural gas extraction and purification.
use--
The plate gate valve with diversion hole can be used for the medium containing a large amount of impurities. It should be used with diversion holes, which can automatically flush the impurities in the valve cavity. Generally used in venting systems and oil and steam storage devices, flat gate valves are suitable for natural gas, petroleum, chemical, environmental protection and other transportation pipelines, as opening and closing equipment
Flat gate valves without diversion holes are used on pipelines that do not need to be cleaned. The flat gate valve without diversion hole has unique structure, convenient sewage discharge, is not restricted by on-site scenting, and can be installed at any angle.
