About Slab Gate Valve

FlowBiz brand Slab / Conduit Gate Valves provide a seat that adopts the O-Ring seals and oat valve seat structure before

tightening. The soft sealing inlays fluoroplastic offers the function of double-sealing.

Flowbiz provides two variants of metal to metal & Fluoroplastic to metal. Fluoroplastic removes the dirt from the Gate and disc.

Injecting the sealing component through the grease injection nipple outside the valve gives the seat to achieve bubble tightness.

The Slab Gate Valve structure ensures the Gate's tightness against the seal whether the disc is open or closed. The flow resistance coefficient is negligible in the Full open position, resulting in almost no pressure loss. The seal is protected from the media, extending the product's service life.

Product Features:

1. The valve seat adopts the O Ring seals and oat valve seat structure before it tightens. The soft sealing inlays fluoroplastic provides double sealing; fluoroplastic to metal and metal to metal. At the same time, fluoroplastic can remove the first gate disc.

2. A grease injection nipple outside the valve injects the sealing component through the seat to achieve bubble tightness.

3. Slab Gate Valve structure ensures the Gate's tightness against the seal whether the disc is open or closed. The flow resistance coefficient is negligible in the fully open position, resulting in almost no pressure loss. The seal is protected from the media, extending the product's service life.

Superior Sealing and Flow Capacity

This slab gate valve features a full bore structure, providing unrestricted flow and reducing pressure drop. Its bi-directional sealing ensures reliable shut-off in both flow directions, making it suitable for intricate pipeline and process conditions. With soft and metal-to-metal sealing options, the valve caters to diverse media like oil, gas, and water.

Versatile Applications and Configurations

Designed for critical sectors such as pipelines, petrochemicals, refineries, and power generation, the valve offers multiple end connections-including RF/RTJ flange and butt weld-to accommodate varied installation demands. Available for port sizes from 2" to 48" and pressure ratings up to Class 2500, it adapts to complex operational requirements with a range of manual and automated operation modes.

Advanced Material and Durability

Constructed from robust materials like carbon steel, stainless steel, and alloy steel (including ASTM A216 WCB, CF8/CF8M, and Alloy 20), these slab gate valves offer excellent resistance to corrosion and harsh process media. Epoxy painting or client-specified coatings further enhance protection, supporting an impressive service life and minimizing maintenance costs.

FAQ's of Slab Gate Valve:

Q: How is a slab gate valve operated in different industrial applications?

A: Slab gate valves can be operated using a handwheel for manual control, a gear mechanism for easy turning, or with actuators-pneumatic or electric-for automated processes. The choice depends on the required control precision, frequency of operation, and integration into facility systems.

Q: What are the benefits of using a full bore, bi-directional slab gate valve in pipelines?

A: Full bore design allows unrestricted fluid flow, minimizing pressure drop and turbulence. The bi-directional sealing provides reliable shut-off in both directions, enhancing system safety and reducing the risk of leakage even under high-pressure conditions.

Q: When should a client select metal-to-metal sealing versus soft-seated options?

A: Metal-to-metal sealing is ideal for high-temperature, abrasive, or corrosive media, offering durability and longevity. Soft-seated valves are suited for lower temperature services or where bubble-tight shut-off is required, improving sealing efficiency for clean fluids like water, oil, or gas.

Q: Where can these slab gate valves be installed, and which industries use them most?

A: These valves are commonly installed in oil and gas pipelines, petrochemical plants, refineries, and power plants. Their robust construction and versatile connection types make them ideal for both new construction and upgrades in these demanding industries.

Q: What is the process for testing slab gate valves before dispatch?

A: Each valve undergoes rigorous hydrostatic and pneumatic pressure tests in accordance with API 598. This ensures integrity, functionality, and adherence to performance specifications, providing peace of mind to operators and end users.

Q: How does the surface coating enhance the service life of these valves?

A: Valves are epoxy painted or coated as per client requirements, providing an added barrier against corrosion and harsh environmental conditions. This protective layer prolongs the valve's service life while reducing ongoing maintenance needs.

Q: What is the typical service life and maintenance requirement for these valves?

A: Thanks to their durable construction materials and advanced coatings, slab gate valves offer long service life with minimal maintenance. Regular inspections and scheduled servicing ensure optimal performance even in challenging operational environments.
