Flat gate valve
Product Classification:
Key words:
A parallel slide gate valve is a sliding valve with a parallel gate plate as its closing member. The closing member can be a single gate plate or a double gate plate with a supporting mechanism in between. It is mainly used in natural gas, petroleum, chemical, environmental protection, urban pipelines, gas pipelines and other conveying pipelines, venting systems, and gas storage devices as an opening and closing and regulating device. A gate valve with a flow-guiding hole is used in pipelines requiring pigging, while one without a flow-guiding hole is used in pipelines that do not require pigging. This product has a novel structural design, convenient operation, and strong corrosion resistance, wear resistance, and erosion resistance, making it an ideal new type of equipment in the petroleum industry.
