Features of Square Knife Gate Valves

This knife gate valve is mainly used in the mining and food-processing industries。 The dual elastomer valve seat and sliding door design facilitate self-cleaning and prevent medium accumulation. The durable ductile iron valve body adopts a compact plate design. When fully opened, the valve has a full diameter and no resistance to the pipeline medium.

BODY'S CONSTRUCTION

Cast iron, stainless steel, aluminium or aluminium hard anodised ( resisting to abrasion avoids forming of alumina in surface).

Features of Square Knife Gate Valves

This type of knife gate valve can be customized with an ISO5211 standard platform, suitable for manual, pneumatic, and electric actuators.

Welded assembly construction.

Body and gate in rectangular valve shape.

All the solutions of actuators, detection and accessories are identical to the GKV standard valves.
