TECHNICAL BULLETIN Valbart TCSGV Through Conduit Slab Gate Valve Experience In Motion
Tight shutoff in liquid or gas services The Valbart TCSGV through conduit slab gate valve is manufactured and tested in accordance with API 6D, latest edition. Its design is fully compliant to ASME Section VIII, Division 1 (ASME Boiler and Pressure Vessel Code: Rules for Construction of Pressure Vessels). Additionally, the design meets API 6D isolation features of block and bleed, double isolation bleed (DIB-1), double block and bleed, cavity relief, and other requirements commonly specified in the pipeline industry. The Valbart TCSGV valve design features a full-bore diameter, which makes it suitable for use in pigging applications. Valbart TCSGV slab gate valves are engineered to achieve tight shutoff at high and/or low pressures in liquid or gas services. Springenergized seats and a floating slab gate provide low-pressure as well as high-pressure sealing integrity. Slab gate applications Valbart TCSGV through conduit slab gate valves are typically used in the oil and gas industry for installation in liquid products and secondary recovery, midstream and downstream pipelines. Typical applications include, but are not limited to: Mainline block valves Tank and station valves Manifold valves Launcher/receiver trap valves Meter bypass valves Emergency shutdown valves Transmission and distribution pipelines The engineered bore sealing mechanism of the TCSGV valve is the primary metal-to-metal seat and secondary soft seat. This configuration provides reliable soft sealing and uncompromised metal sealing for severe/heavy-duty services involving: Abrasive fluids and sandy services High-temperature services Service conditions requiring full reliability such as emergency shutdown valves (ESDV) 2
Positive sealing mechanism The spring-energized seat (Figure 1) of the TCSGV valve is designed to push against the slab gate for continuous contact and positive sealing, even at low pipeline pressures. The floating slab and seats enable fluid pressure to assist the sealing by compressing the slab into the seat tighter as pipeline pressure increases. Medium- to high-pressure sealing is accomplished by the upstream seat pressure sealing against the slab. Even the downstream seat is dynamically energized by the upstream pressure due to the floating slab, as shown in Figure 2. A double-sealing barrier is provided against the upstream pressure. The sealing mechanism of the TCSGV valve operates as follows: Slab gate moves up and down and enables open and close positions of the valve Springs on the seat rings help in sealing at low pressures; self-energized seal is achieved at slightly higher line pressures Both seats and gate are floating, allowing simultaneous upstream and downstream sealing Bore sealing mechanism by position; no wedging effect required Figure 1: Springenergized floating seat detail Figure 2: TCSGV valve sealing 3
Sealing application capabilities Bi-directional, bubble-tight sealing Valve seats are designed to seal against upstream or downstream pressure sources in either direction with the cavity vented. See Figure 3. Figure 3: Bi-directional sealing P A = upstream pressure P B = downstream pressure P C = cavity pressure Block and bleed (BB) types A and B (API 6D) In its closed position, at least one sealing surface provides sealing against pressure from one end of the valve (P A or P B ) with the body cavity vented (P C = 0). Double block and bleed (DBB) types A and B (API 6D) In its closed position, two seating surfaces provide sealing against pressure from both ends of the valve, with a means of venting or bleeding pressure in the cavity between the seating surfaces. See Figure 4. Figure 4: DBB upstream side (P A ) and downstream side (P B ) simultaneously isolated with cavity vented Double isolation and bleed (DIB) types A and B (API 6D) Figure 5: DIB Downstream seat provides isolation against cavity pressure. In its closed position, each of the two seating surfaces provides a seal against pressure from a single source, with a means of venting or bleeding pressure in the cavity between the seating surfaces. See Figure 5. 4
Design features Fabricated body construction with engineered ribs profile The TCSGV slab gate valve has a robust fabricated design with a high strength over weight ratio. The engineered ribs profile is a result of extensive finite element analysis for optimizing strength over weight and ensures that material is placed where needed. This minimizes body and seat deflection and also ensures solid sealing performance up to the valve s rated pressure. See Figure 6. Figure 6: FEA analysis on slab gate valve body Electroless nickel plated (ENP) with low-friction coating The slab, seat and stem are treated with ENP and low-friction coating to reduce operating forces and torque. Reduced friction also improves wear on seat and slab surfaces. Self-relieving per API 6D, latest edition Excess cavity pressure is relieved by the valve seat to the pressurized side, ensuring double isolation at the downstream end. See Figure 7. Pressure-energized floating seat The floating seat design and piston effect force generated by the line pressure ensure continuous and uniform contact between the seat and slab gate, proportional to the line pressure. Figure 7: Self-relieving mechanism 5
Advanced slab guiding system The slab gate guiding system supports the weight of the slab and eliminates damage to the seats caused by its weight. It allows for the valve to be mounted in both vertical and horizontal orientations without compromising sealing performance. Figure 8: Slab guiding system detail The slab guiding system consists of two bars that keep the slab in position within the valve body to ensure precise opening and closing. See Figure 8. Bore sealing by stem position No wedging effect and operating thrust, regardless of the temperature range. No side loads to the stem The floating seat and gate design ensures low operating thrust. The stem is guided by a low-friction, coated bearing. See Figure 9. Figure 9: Floating motion of slab and seats 6
Self-cleaning seat The collection of process fluid debris in the soft seating area is eliminated by the metal seat acting as a scraper. The self-cleaning seat improves uptime and reliability by removing any build-up of debris that may have accumulated on the slab. See Figure 10. Figure 10: Self-cleaning seat Top-entry design Simplified maintenance and repair are enabled by the 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. See Figure 11. Figure 11: Top-entry design allows in-line maintenance. 7
Blowout-proof stem design The TCSGV valve s stem design retained in the bonnet as per API 6D requirements improves personnel and plant safety. See Figure 12. Figure 12: Blowoutproof stem design Sealant injectors The Valbart TCSGV valve incorporates a seat and stem sealant injector design. These ports enable the injection of sealant to restore the valve s sealing capability. See Figure 13. Figure 13: Sealant injectors 8
Seat design The TCSGV valve s seat design is a solid metal single-piston effect seat, including grease injector holes as a standard feature. Figure 14 shows the seat design along with seat housing components, while Figure 15 details the seat sealant injector and the sealant pathways. Figure 14: Seat and seat housing details Figure 15: Seat sealant injectors and pathways Chevron-style stem seal PTFE chevron packing provides an effective, low-friction stem seal, for long life under adverse operating conditions. The double packing set design ensures a robust seal against potential fugitive emissions, while the additional graphite ring guarantees fire safety. A sealant injection fitting is provided for emergency sealing if needed. See Figure 16.

Limitorque offers electric MX actuators (Figure 19), complete with V Series (Figure 20) gear box and controls to meet any valve thrust and customer application requirement. Stateof-the-art, non-intrusive control systems allow operators to calibrate and locally control the actuator and valve without removing the actuator cover. Actuators are available with SIL capability for meeting enhanced safety integrity requirements. Various digital protocols and network communications can be offered for compatibility with numerous controls systems, including ModBus, DeviceNet and Foundation Fieldbus. Limitorque heavy-duty electric actuators provide the reliability, robustness and features to meet the needs of the oil and gas industry. Different actuators or special applications are available upon request. Figure 19: Limitorque MX electric actuator Valve automation center Operator mounting should be performed at a Flowserve valve automation center before shipment. If the operators are to be on-site, the mounting should be carried out before installing the valves in-line, as per Flowserve instructions. Mounting of operators on valves already installed in-line is not recommended; if performed, it should only be done under the supervision of Flowserve personnel. Figure 20: V Series bevel gearboxes are easily adapted for motorized operation by MX actuators. 18
