Reliable Performance
Built for stable and dependable operation in oilfield wellhead and manifold service.
Body & Bonnet Construction
All API 6A Slab Gate Valve bodies and bonnets are forged or cast from high-quality AISI 4130/4140 low-alloy steel or AISI 410 stainless steel. For harsh and extreme service environments, optional materials including Inconel and duplex stainless steel are available to meet customized oilfield project requirements for your API 6A Slab Gate Valve.
Metal-to-Metal Sealing System
Precision-lapped gate and seat surfaces of our API 6A Slab Gate Valve create durable metal-to-metal pressure-tight sealing. Both sides of the valve seat are finely lapped to ensure full and stable contact between the seat and valve body. The primary metal seal is reinforced by a Teflon or Viton lip secondary seal, achieving bubble-tight sealing performance at working pressures below 10 psi.
The reusable sealing structure greatly improves slab gate valve service life and reduces maintenance costs.
Gate & Seat Design Slab Gate Structure
Fully floating seats combined with a rigid solid slab gate provide reliable downstream sealing with extremely low operating force, ensuring flexible and stable API 6A Slab Gate Valve operation.
Expanding Gate Structure
The expanding gate mechanism provides positive mechanical sealing with or without line pressure. Floating resilient seals allow the seats to wedge tightly into seat pockets in both fully open and fully closed positions, delivering consistent sealing performance under variable pipeline pressure for your API 6A Slab Gate Valve.
Precision Gate Guiding System
The gate of the API 6A Slab Gate Valve is accurately guided by the valve body and close-fitting stainless steel skirts. The protective skirt structure effectively reduces the ingress of mud, sand and well fluid into the valve body cavity, protecting internal components and improving slab gate valve durability in harsh oilfield field conditions.
Body to Bonnet Metal Seal Adopting professional metal-to-metal sealing technology between body and bonnet, the API 6A Slab Gate Valve achieves high-pressure tightness. The seal ring is reusable, reducing replacement frequency and lowering long-term operation expenses of your oilfield slab gate valve.
Flange Connection Slab Gate Valve (Without Balance Stem) Non-Rising Stem with Backseat The slab gate valve stem is made of nitrided alloy steel or 17-4 stainless steel with high strength and corrosion resistance. The non-rising stem design avoids internal pressure buildup during valve operation. Equipped with a reliable backseat sealing structure, this API 6A Slab Gate Valve allows safe on-line replacement of stem packing even when the valve is under working pressure, greatly improving maintenance convenience.
High-Performance Stem Seal
Stem seals of our API 6A Slab Gate Valve adopt non-elastomeric PTFE / R-PTFE materials, which are chemically inert to most liquids and gases. The optimized sealing structure minimizes friction and reduces operating torque. It is applicable for a full range of temperature and service conditions. Graphite stem packing is available as an optional upgrade for special working environments of your API 6A Slab Gate Valve.
Heavy-Duty Bearing System
Equipped with heavy-duty thrust bearings, the API 6A Slab Gate Valve efficiently bears stem thrust and reduces operating torque. A grease fitting on the bearing cap allows convenient regular lubrication, ensuring smooth, stable and trouble-free long-term slab gate valve operation.
Hydraulic API 6A Slab Gate Valve Available
Fuzer also provides hydraulic operated API 6A Slab Gate Valve versions for automated pipeline control, suitable for remote operation, unmanned stations and intelligent oilfield systems. Our hydraulic slab gate valve is widely used in wellhead and manifold projects.
