Vahn-Tech DC Series knife gate valves are linear shut off valves that are light weight with compact construction. Valves are available as manual with handwheel, or can be automated with pneumatic cylinder or electric actuator for remote operation. The arc shape of the gate of our knife gate valve is designed to be particularly suitable for cutting off fluid containing fiber or suspended particles. The knife gate valves are ideal for many applications in the process industries of Pulp & Paper, Wastewater Treatment, Mining, Sugar Making and Chemical Processing.

Features & Benefits
- Double Stem Bearings at the top of the yoke for easy operation and for torque reduction
- Internal packing and packing gland are internally loaded, ensuring a tight seal and preventing leakages
- Travel aligning block installed at the inlet of the body serves as a supportive force to regulate the flow of the accumulated medium between the gate and body cavity
- Seats are backed with an o-ring to give the seat a self-compensating wear function; this results in excellent seat tightness and prolonged life cycle
- Gate is designed with standard precision ground and hard plated chrome which provides superior abrasion and corrosion resistance
