Vahn-Tech high performance 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

·       VAHN-TECH knife gate valves are equipped with two stems bearing at the top of the yoke for easy operation and for torque reduction.

·       Packing and packing gland are internally installed, ensuring a tight seal and preventing leakages.

·       Travel aligning block is made of soft materials with stainless steel screw installed at the inlet of the body. It serves as a supportive force to regulate the flow of the accumulated medium between the gate and body cavity. Ensuring an excellent tightness and preventing clogging risk when closing.

·        Seats in the VAHN-TECH knife gate valves 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. When seats do wear and need replacement, maintenance to change the seats is easy and fast. Available seat materials are metal, EPDM and PTFE seated. For other inquiries regarding seat selection please contact us.

·       Each gate is designed with standard precision ground and hard plated chrome which provides superior abrasion and corrosion resistance. The arc shape design of the bottom of the gate is exceptionally suitable to provide strong cutting force for pulp media.
