Stainless Steel Knife Gate Valve, A351 CF8M, 16 IN, NRS, Lug

Key Specifications / Features

The Stainless Steel Knife Gate Valve Plant offers a robust Non-rising Stem Gate Valve designed for unidirectional flow. Constructed from high-quality ASTM A351 CF8M stainless steel, this 16-inch (DN400) valve features Class 150 LB and PN20 pressure ratings, ensuring durability and reliability in demanding applications. Its lugged ends facilitate easy installation and maintenance, making it an ideal choice for industries requiring precise flow control and corrosion resistance.

The KN-series manual knife gate valve is a unidirectional wafer-type valve designed for on-off operation in industrial pipelines. Its body and seat design prevent clogging, ensuring reliable shutoff even with media containing fine particles. The beveled knife edge enables the gate to cut through thick or viscous media with ease. To suit different operating conditions, a range of configurations is available, including non-rising stem, wafer, lugged, pneumatic, electric, manual, and bevel gear-operated knife gate valves.
