ROUND BY SQUARE PORT KNIFE GATE VALVE

The CR model knife gate is a heavy duty valve designed for handling difficult applications. This valve is suitable for use in recycle applications, like junk or sand traps of pulpers, high consistency cleaners,... or as silo outlet with solid material.
The two piece body with round inlet and square outlet (larger than the inlet) assures non-jamming.

DOUBLE GATE KNIFE GATE VALVE

The DT model knife gate is double gate valve widely used in the Pulp and Paper industry (recycling or secondary fibre processing) designed to handle high concentrated or contaminated media. In open position, both gates retract into the body and allow full flow. When closing, the gates push stock and contaminants as staples, wires,... out of the body into the flow.
Stroke time is the half of conventional valves.
All components subject to wear are replaceable.
