What is a Double Acting Cylinder Operated Knife Edge Gate Valve?

A Double Acting Cylinder Operated Knife Edge Gate Valve is an automated industrial gate valve where a pneumatic double-acting cylinder actuates the gate, removing the need for manual handwheel operation. Built with a wafer-type lugged design, it offers precise, repeatable actuation for fast-cycling process lines handling slurry, pulp, or solid-laden media, with material options for demanding environments up to 900°C.

Applications of Double Acting Cylinder Operated Knife Edge Gate Valve

Suited for automated flow control in pulp & paper, wastewater treatment, power plants, mining, steel plants, and chemical process lines — especially where frequent cycling, remote actuation, or high-temperature service makes manual operation impractical.

Benefits of Double Acting Cylinder Operated Knife Edge Gate Valve

• Fast, precise, repeatable operation via pneumatic actuation
• Zero-leakage gland sealing for reliable long-term isolation
• High-temperature capability up to 900°C
• Wide material selection for corrosive or abrasive applications
• Reduces manual intervention, improving safety and efficiency

Working of Double Acting Cylinder Operated Knife Edge Gate Valve

The double-acting cylinder receives pneumatic pressure on either side of its piston, driving the gate plate vertically to open or close the valve. Because both strokes are power-driven, the valve delivers consistent force and speed in both directions — unlike single-acting designs that rely on a spring for one stroke. The gate seats against the integral seat with the chosen sealing material, while gland packing prevents leakage along the spindle for dependable shut-off every cycle.
