Round Knife Gates are manufactured in two basic forms Hand operated or Chain Wheel operated. Laser profiling results in a light but robust knife gate. The inlet ports are generously sized with a protective wear ring insert. This wear ring ensures that contact of material with the sealing strip above the gate plate is minimized reducing wear and maintenance. The outlet port opening is larger than the inlet ensuring minimal chances of material hangup.
The design of the stuffing box is such that the packing can be changed with the knife gate blade in position. The Hand Wheel operated valve uses a conventional hand wheel while the Chain Wheel operated version is ideal for hand operation where the gate is installed in an elevated position. Limitor proximity switches can be fitted as optional extras.
