Product Description

Knife Gate Valve Model 101 is designed to shut off the flow of medium in industrial pipelines. It features a simple and reliable construction and is capable of operating in harsh conditions, including with media containing solid particles. The seal is securely fixed in the body by a metal retaining ring. Advantages of this model include ease of maintenance and the option to install a flushing line at the bottom of the body, which prevents the valve from jamming during operation in environments with a high content of abrasive particles.
