WKM Saf-T-Seal Slab Gate Valve
The 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 the passage of all types of scrapers (pigs).
The WKM Saf-T-Seal 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 the flow
- Block-and-bleed capability
- Commonly used applications
