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.

Face to Face:	MSS SP-81
Flange Standard:	GB/T 9113.1, JB/T 79.1, HG 20592, ASME B16.5, EN1092-1
Applications:	Pulp & Paper,  Water Treatment,Beverage & Food,Fine Chemical,       Power Planet,Steel Industry, etc.

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.
