WKM™ Saf-T-Seal™
Slab Gate Valve
Stock available today in 2″ – 36″, ANSI 150# – 900#
Carrying T101 & T24 models with Low Alloy & T24 Stainless Steel
The Cameron WKM Saf-T-Seal slab gate valve is a simple, yet rugged and reliable, through-conduit valve. It utilizes two floating seats to provide a complete seal with the gate. Each seat contains a metal seat face plus a peripheral seal. The full bore design has the same pressure drop as an equivalent length of pipe and allows passage of all types of scrapers (pigs).
The WKM Saf-T-Seal slab gate valve’s through-conduit design provides these specific advantages resulting in reliable performance and long life:
• Protection of seat faces
• Smooth, continuous conduit for flow
• Block-and-bleed capability
• Commonly used applications

WKM™ Saf-T-Seal™ Slab Gate Valve
Simple yet rugged slab gate valve design for reliable through-conduit serviceThe WKM Saf-T-Seal slab gate valve is engineered for dependable isolation in demanding pipeline environments where simplicity, durability, and consistent sealing are required. The valve uses two floating seats that seal directly against the gate, creating a complete and reliable shutoff. Each seat incorporates a metal face with a peripheral seal to maintain integrity under varying pressure conditions.
The fullbore, through-conduit design produces the same pressure drop as an equivalent length of pipe and allows unobstructed passage of all types of scrapers and pigs. This makes the slab gate valve well suited for systems requiring frequent pigging and uninterrupted flow performance.

Applications for Slab Gate Valves
The WKM Saf-T-Seal slab gate valve is designed for a wide range of pipeline and facility applications, including mainline and manifold valves, tank and station valves, and storage wells. It is commonly used in brine-flood and waterflood operations, as well as safety valves or emergency shutdown (ESD) valve applications. The valve is also increasingly specified for CCUS, renewable fuels, and ammonia service where dependable isolation and compliance are critical.Benefits of the WKM Saf-T-Seal Slab Gate Valve
Designed for reliable performance and long service life, the Saf-T-Seal valve’s through-conduit configuration provides protection of seat faces and a smooth, continuous conduit for flow. The design delivers block-and-bleed capability and supports inline field repairs, helping reduce downtime and maintenance costs. Fire-safe certification to API Spec 6FA and ISO 10497, along with fugitive emissions certification to ISO 15848-1, supports use in regulated and safety-critical pipeline systems.Design Features of This Slab Gate Valve
The stem seal uses a single SLS™ spring-loaded lip seal that has been fugitive-emissions and fire tested, reducing maintenance requirements and eliminating the need for plastic packing. Spring-loaded seats relieve internal body pressure to protect sealing components. A stem back seat per API Spec 6D prevents stem ejection, while a metal-to-metal seal between the stem and bonnet in the upward position isolates the stem seal from line pressure. Seat and stem injection ports allow lubricant or emergency sealant to reduce operating torque, extend valve life, and provide emergency sealing capability. Installation orientation is flexible.Frequently Asked Questions
How does a slab gate valve differ from an expanding gate valve?
A slab gate valve uses a solid gate with floating seats to seal against the gate surface,
while expanding gate designs rely on mechanical expansion. This makes slab gate
valves ideal for piggable, through-conduit service.
Is the Saf-T-Seal valve suitable for emergency shutdown applications?
Yes. The WKM Saf-T-Seal slab gate valve is commonly used as a safety or ESD valve
due to its reliable sealing, fire-safe certification, and robust mechanical design.
Can this slab gate valve be serviced in the field?
Yes. The valve is designed to support inline field repairs, helping minimize downtime
and simplify maintenance in pipeline and facility installations.
