Through Conduit-Slab Gate Valves

Through Conduit-Slab Gate Valves provide superior gas-tightness and unmatched robustness in demanding services involving high pressure, high temperatures and solid particles. The full bore channel design minimizes the turbolity of the flow and when the valve is open, the pressure drop is equal to that produced by a pipe of the same diameter and length. Moreover, the valve is perfectly suitable for pigging operations.

Trough Conduit / Slab Gate Valves are used for the following applications: -Offshore platforms -Coastal terminals -Transmission lines

Commonly used Fluid types are: -Non-corrosive liquids -Gas – H2S and H2SO4 -Water – Hydrocarbons

Trough Conduit / Slab Gate Valve Types

Trough Conduit Gate Valve is a typical parallel gate valve. slab gate valve is in two series, slab gate valves are in two series: self-draining and self-expanding slab gate design. It is one of our skills to reduce the operation torque when opening and closing the pressure balanced shaft.

Design Features

The Slide and Seat are overlapped in a mirror polished finish, thus reducing milking and preventing damage to the seat. The body and cover connection is precision machined with high surface quality shaft and sealing. There is valve technology with low emission with an optimized design for long service life. Low compression packing reduces friction and provides more space for re-torqueing. Packing ring construction for excellent sealing and anti-corrosion. Valve is piggable due to Full Bore configuration. Option: live loaded packing bolting Double packing (top & bottom) design for critical services.

Application Areas

Trough Conduit / Slab Gate Valves can be used for a wide range of applications in the oil & gas and petrochemical industries where high quality and highly reliable valves are required. A few example applications include: ⦁ High temperature applications ⦁ Emergency shut-off valves (ESDV) ⦁ (HIPPS) applications ⦁ High pressure oxygen, nitrogen or hydrogen ⦁ Solids processing (thin parts, dust and catalyzers) ⦁ Polyethylene or polypropylene ⦁ Coal conversion and gasification ⦁ Thermal fluids ⦁ Separator, filter and drying systems ⦁ Compressor stations ⦁ On-OFF insulation ⦁ Oil and Gas manifolds
