Slab Gate Valve Definition

Scv valve manufactures some of the most dependable cast steel thru conduit slab and expanding gate valves in the industry.

Slab gate valve definition.

Valve depicted with bonnet grease fitting rotated toward flange forged body omni model fs forged body slab gate valves are designed for oil and natural gas wellhead manifold or other critical service applications. This type of valve is very useful in transportation pipe lines for gas crude oil and oil products. Therefore virtually no resistance to. A gate valve also known as a sluice valve is a valve that opens by lifting a barrier gate out of the path of the fluid gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened.

060 or 065 is for wedge gate valves xfig. A generally u shaped spacer member of substantially the same thickness as the slab gate is loosely positioned between the opposed seat assemblies outwardly of the slab gate to maintain a predetermined minimum spacing between the seat assemblies. 074 is for slab gate valves with dismountable seats fig. 072 is for wafer type slab gate valves xfig.

A gate valve structure having a slab gate and a pair of opposed seat assemblies on opposite faces of the slab gate. Slab gate valve through conduit rising stem design walworth slab gate valves also named through conduit gate valve are manufactured and tested in accordance with the api 6d standard. 060 065 fig. In service these valves are either in a fully open or fully closed position.

Both designs utilize flanged and butt weld end connections and are manufactured and tested in accordance with api 6d. A gate valve is the most common type of valve used in any process plant. It is a linear motion valve used to start or stop fluid flow. The full port bi directional flow capability minimizes pressure drop and turbulence.

Many of the features of the fl valve design are common to our type f gate valve which was introduced to the market in 1958. Strahman gate valves have three different configurations. Available in sizes 1 13 16 through 4 1 16 for 2 000 through 15 000 psi service slab gate field replaceable. When the gate valve is fully open the disk of a gate valve is completely removed from the flow.

074 strahman gate valve sealing systems utilize different designs for wedge and slab valves. The gate faces can be parallel but are most commonly wedge shaped in order to be able to apply pressure on the sealing surface.
