Slab Gate valves are manufactured and tested in accordance API-6D. This type of valve is very useful in transportation pipelines for gas, crude oil, and oil products. The Slab Gate valves are thru-conduit and piggable.  The slab gate when opened interior has been designed to minimize pressure drop and catch foreign materials into the disc cavity and also avoid the turbulence of the fluid throughout the valve.

Slab Gate valve uses the resultant force from line pressure to help to have a Mechanical and tight sealing in downstream side when high differential pressure occurs. Low pressure sealing is achieved by internal springs assisting in pushing the seat ring against the gate to obtain the seal.
