Forged Steel Parallel Slide Gate Valve

The parallel slide valve design relies on the primary system pressure acting on the downstream disc for seat integrity. There is no wedging action or extra loading on the seats. As a result, the closing torque is comparatively lower, requiring less manual operating effort or smaller power actuators. Due to its inherent design, the parallel [...]

Slurry Knife Gate Valve

This type of slurry knife gate valve is recognized as the most durable and user friendly knife valve designed for difficult slurry applications. When the valve opens, the reinforced elastomer sleeves seal against each other and provide a 100% full port opening, which minimizes turbulence, which in turn eliminates wear. The seats isolate and protect [...]
