Your Professional Valve Solution


Slab Gate Valve

Slab gate valves are comprised of a single gate unit which raises and lowers between two seat rings and are primarily used for transporting crude oil and natural gas.
The design of product structure is very novelty. Appropriate material selection, strict testing, convenient operation, all these aspect make flat gate valve become an ideal equipment. Besides, flat gate valve has the function of anti-corrosion, wear-resistant, resistant to erosion. Slab gate valve is suitable for natural gas, petroleum, chemical industry, environmental protection and urban pipeline, gas pipeline conveying pipeline.
