The Valbart Through Conduit Slab Gate Valve (TCSGV) is the oil and gas industry’s choice for liquid and gas applications requiring a reliable, tight shut-off valve to prevent leakage and minimize losses from process contamination.

The TCSGV utilizes a through conduit, slab gate design with a full-bore diameter, making it ideal for pigging requirements. Spring-energized seals and a floating slab gate ensure low- and high-pressure sealing integrity. In low pipeline pressures, the spring-energized seal pushes against the slab gate for positive sealing and continuous contact. The floating slab gate and seats are designed to allow fluid pressure to assist the sealing process by compressing the slab tighter into the seat as pipeline pressure increases.

The TCSGV incorporates unique design features, such as slab gate guides and an engineered ribs profile, to improve valve performance and increase product longevity. For maximum application versatility, it can be mounted in both horizontal and vertical positions.

The TCSGV design meets functional and isolation requirements commonly specified in the pipeline industry, including: block and bleed, double isolation bleed (DIB - 1), double block and bleed, and cavity relief. The valve is well-suited for a wide variety of liquids and gas pipeline service applications, providing industry-leading value through an engineered design that is cost-effective and requires low maintenance.

Key Benefits• Improved sealing and tight shut-off performance with

bi-directional sealing in both upstream and downstream sides, even at low pressures, due to the seat spring compression action of the seat against the slab

• Minimized wear and tear and increased life of sealing components through low-friction, slab gate guiding mechanism

• Cost-effective actuation from low operating thrust requirements provided by keeping seat and gate in a floating position which are unaffected by side loads

• Robust assembly and minimized deformation from internal pressure due to optimized structural design with engineered ribs profile that results in an enhanced strength over weight ratio

Engineered pipeline design Functionally qualified and monogrammed API 6D to meet the most stringent pipeline design standards

Ensured fire safety Tested and certified to API 607/API 6FA fire-safe standards, the Valbart TCSGV provides pipeline protection in the event of fire

Improved seat leakage resistance Seat tightness conforms to API 6D, ISO 5208 standards

Minimized fugitive emissions Proven stem seal design meets ISO 15848 – 2 Class B to satisfy the most demanding fugitive emissions specifications

Higher corrosion resistance Materials and fabrication welds are selected and qualified to hardness and NDE requirements of NACE MR0175

Engineered to Exceed Industry Standards

Slab Gate Guiding SystemA two-bar guiding system keeps the slab in position within the valve body to ensure precise opening and closing operation in both vertical and horizontal mounting orientations. The guides are coated with ENP for minimized friction and reduced wear between them and the slab gate. Contrary to traditional horizontally mounted, welded gate valve designs, the TCSGV provides improved and longer lasting sealing performance. The unique slab gate guiding system supports the weight of the slab and eliminates damage to the seats caused by the weight of the slab.

Easy In-line MaintenanceSimplified maintenance and repair is enabled by a top-entry design that allows for easy access to valve components while the valve is still in-line. Equipment downtime is dramatically reduced as trim and internal components can be replaced with ease in a relatively short period of time.

Engineered Ribs ProfileThe slab gate valve is designed with an engineered ribs profile to ensure that valve body material is used selectively to enhance the robustness of the valve in critical body areas. The ribs profile is optimized for strength over weight through extensive finite element analysis, following the stress pattern of the valve to identify body areas that are subject to more stress and then placing material at those locations. This enhances valve body strength and improves sealing performance up to the rated valve pressure while minimizing body and seat housing pocket deflection.

Bi-directional, Bubble-tight Sealing Bi-directional, bubble-tight sealing is guaranteed by spring-energized seats which are compressed against the slab to provide tight shut-off at low and maximum (rating) pressure. Additionally, the floating trim design automatically energizes the downstream seat to provide an additional second sealing barrier. The standard sealing mechanisms are primary metal-to-metal and secondary soft for a combination of reliable metal sealing and efficient soft sealing in severe service applications.

Minimized Damage to Soft InsertsThe collection of dust and debris in the soft sealing area is eliminated by the metal seat that also acts as a scraper (self-cleaning seat) to remove any debris and dust that has accumulated on the slab.

Bore Sealing by Stem Position to Eliminate Wedging EffectThe TCSGV construction solves the problem of wedging by not allowing the sealing components to wedge against each other. Instead, sealing is achieved through a simple operation of the slab sliding to close the valve. This eliminates the wedging effect commonly seen in other valve designs that cause the interior components to expand from temperature and pressure, making it difficult to un-wedge the obturator.

Seat and Stem Sealant InjectorThe Valbart TCSGV incorporates a seat and stem sealant injector design to enable the injection of sealant to restore the sealing capability of the valve.

Blowout-proof Stem DesignThe TCSGV’s stem design — retained in the stem cover per API 6D requirements — improves personnel and plant safety.
