Feature

This type of knife gate valve is a bidirectional valve deals with flow in both directions, while offering 0 leakage. The u–shape peripheral seat design ensures full-port flow and non-clogging shutoff. It is suitable for media such as pulp stock, chemicals, sludge, bio mass, slurry and water.

Application:                    

Pulp and Paper/ Mining /Waste Water Treatment/ Food and Beverage/

Chemical Plants/ Power Plants/ Steel Industry/Etc.

Design Features

Body

· Integral body design ensures easy assembly and 0 shell leakage.

· Full port design minimizes pressure drop and maximize flow capacity.

· Cavity free bore prevents valve body from any particle accumulation.

Gate

· Beveled knife edge provides strong cutting stress and tight sealing.

· Gate thickness can be increased to meet higher pressure.

· Gate surface is well polished at both sides for tight seal and less jamming.

Seat

· U-shaped elastomer seat provides a peripheral seal along the edge of the gate and ensures tight seal in both flow directions.

Other:

· Stem cover is available to ensure long service life for stem.

· Two thrust bearings minimize operation torque.

· Grease nipple is available for bearing lubrication.
