Industrial valves DOUBLE GATE KNIFE GATE VALVE K|251 MODEL

Double gate knife gate valve solutions for the pulp and paper industry.

DESCRIPTION

At PARAVALVES, every product is carefully engineered as all the neccesary parameters are studied to develop our solid and reliable knife gate valves.

Double Gate knife gate valves are specially made for the pulp and paper industry, for pulp outlets or under silo applications. The design allows flow media with high consistency either for normal or reverse flow due to the bi-directional double seat design. The high flow coefficient value of this knife gate valve provides high flow rates with low pressure drops.

The two-piece construction bolted body retains two knife gates inside. In the open position, both gates are retracted into the body, providing a full bore design.
When the gates closes, they push out the charged fluid out of the body and back into the flow. The stroke of this type of valves is reduced to a half, and so operating time is reduced as well.

Installation of this equipment is done between pipeline flanges, which flange drilling can be made according to customer specifications or PARAVALVES standard. Face to face determines the distance between flanges and this can also be taylor-made to comply with customer project. ButtWelding ends can also be supplied on request.

K251 DOUBLE GATE KNIFE GATE VALVE is able to withstand pressures up to 10bar and can be manufactuered is sizes up to DN1400. Different materials are available such as carbon steel or many stainless steel grades according to required application.
