Production Description:
Knife gate valve is a unidirectional valve used on industrial pipeline for on-off operation.The unique valve structure eliminates potential clogging shutoff when the valve is dealing with flow with particles.Beveled knife gate design also generates great shear stress for easy flow penetration.
Feature:
BODY:
• Cast-in guide claws at the port bottom for gate fixture, instead of a groove, eliminates potential valve     shutoff clogging while providing tighter seal. The guide claws also push gate to seat for tight seal inÂ
 closed position.
• Integral body design ensures easy assembly and 0 shell leakage.
• Full port design minimizes pressure drop and maximize flow capacity.
• PTFE resilient points against gate eliminate metal-metal contact between gate and body.
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.
• Gate is hard chrome coated for metal sealing valve.
SEAT:
• Side-entry seat is replaceable, reducing the cost of maintenance.
• L-shape seat retainer locks seat into valve body and covers seat side to prevent direct flow flushing.
