Through conduit gate valve vs gate valve.

We offer a full range of materials and classes from standard to high and low temperature service based on customer requirements for performance in critical and primary isolation. The through conduit service implies the continuity of fluid flow conduit excluding any dirt accumulation in the body cavity. Both designs utilize flanged and butt weld end connections and are manufactured and tested in accordance with api 6d. During the valve operation the line fluid fills the bore cavity.

Scv valve manufactures some of the most dependable cast steel thru conduit slab and expanding gate valves in the industry. The fluid pressure in the bore cavity generates a vertical force on the stem that pushes the trim from bottom to top. The through conduit expanding gate valve is developed on the basis of slab gate valve. Both the female and male gates are provided with complementary opposed inner faces each formed with two angular related surface portions diverging transversely.

Instead of one slab the disc consists of two halves with a wedge shaped interface. Bel valves through conduit expanding gate valve enables double block and bleed dbb functionality to be achieved within one single valve assembly as opposed to the two conventional slab gates that would otherwise be required.
