Vahn-Tech DK Series knife gate valves are soft sealing shut off valves that are light weight with compact construction, and convenient to install and use. Valves are in full port design and with small flow resistance. When the gate is open, direct current flows between valve and pipeline. Valves can be operated manually with handwheel, or with automatic actuator for remote operation. The cone-shape design of the gates provides strong cutting force. The die-casting rubber seats are with bi-directional sealing. The main advantage of the valves is that when fully open, the medium will not flow into the valve chest, which prevents the pulp from settling in the valve chest and thus reducing the maintenance cost.

Features & Benefits
- Valve body is a two-piece design which is lightweight and compact construction, without any cavities there is no solids accumulation
- Internal packing and packing gland are internally loaded, ensuring a tight seal and preventing leakages
- Arc shape design of the bottom of the gate is exceptionally suitable to provide strong cutting force
- Resilient seat and abrasion resistant rubber seat die cast in a unique rubber mold and have a metal support ring to extend the life expectancy
- Gate is designed with standard precision ground and hard plated chrome which provides superior abrasion and corrosion resistance
- Bottom discharge cover can easily removed from routine cleaning, and can also be outfit with purge system
