Actuator :               

Hand wheel (Rising & Non-rising Stem) ,Electric,Bevel Gear ,Pneumatic (single & double-acting),Chain wheel,Hydraulic,Lever

Standard flange connection:

EN1092,GB/T 9113,ASME B16.5,AS 2129/4087,JIS B2220 ,Others on request

Certificate: 

CE, ISO9001, CE Accredited




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.
