Product Description

Introduction:
The Knife Gate Valve is a unidirectional wafer knife edge gate valve used on industrial pipeline for on-off operation. 
The structure of body and seat eliminates clogging shutoff for flow with fine particles. Additionally, beveled knife edge helps the gate cut through thick media easily.

Features:
1.    Body:
Integral body with full bore structure ensures smooth flow, easy assembly and smaller shell leakage possibility.
Guide claws design at the port bottom for gate fixture, instead of a groove, eliminates any potential clogging when valve shutoff.
2.    Gate:
Beveled knife edge provides strong cutting stress and tight sealing.
PTFE resilient point guider above the port prevents metal-metal contact between gate and body.
Gate thickness can be increased to meet higher pressure.
3.    Seat:
The seat can be replaceable, reducing the cost of maintenance, and alo be adjustable to meet different sealing class and compensate normal seat wear.
