Dimensions in mm, weights in kg.

Dimensions and weights are given as a guide.

On request.

Plate

Standardised to adapt any type of actuator, conform to ISO 5211 standard.

Chevron Seal

Made in nitrile. This device avoids atmospheric contamination.

Bearings

Self-lubricating bearings made of PTFE reinforced on a metallic support. These bearings provide a true shaft guide and ensure absolute shaft rigidity during operation.

Shaft

Inside the disc, it is completely insulated from the liquid being conveyed.

STANDARD KNIFE GATE VALVES DESIGN FEATURES ADVANTAGES OVERS FABRICATED VALVES

Cast stainless steel body and investment cast yoke. In fabricated valves, leakage of corrosive medium due to neglected maintenance on the packing, or line pressure surges causes corrosion and failure of most carbon steel or cast iron components.
An all stainless steel valve offers better corrosion resistance than cast iron lined valves. The total cost of ownership becomes more attractive than the initial savings.:

FIRST ALL STAINLESS STEEL KNIFE GATE VALVE

Rugged one-piece body including flanges. Cast in stainless steel to eliminate corrosion problems that are found with cast iron, or steel valves lined with stainless steel.
All stainless steel investment cast yoke. Up to 12”.
Investment cast stainless steel packing flange the space between the blade and the packing flange is very small and critical on smaller size valves. For 2-8” Enpro knife Gate Valves feature high precision investment cast packing flanges for a tight “contact-free” fit.
