Reliable Pinch Valves for the Toughest Flow Control Applications
When your process involves abrasive slurries, corrosive materials, or high-solids media, traditional valve designs can fail quickly. RF Valve pinch valves are engineered specifically for these harsh conditions, delivering reliable shut-off, longer service life, and simplified maintenance.
Patented no-stretch elastomer sleeve for longer service life.
Self-cleaning valve action prevents buildup and jamming.
Quick, in-line sleeve replacement for fast maintenenace.
Multiple actuation options for flexible control.
Built to handle abrasive, corrosive, and high-solids media.
Self-Cleaning Operation
The pinch action of the sleeve helps dislodge material buildup during each cycle, reducing the risk of blockages and maintaining consistent valve performance.
Maintenance in minutes, not hours!
Sleeve replacement can be completed without removing the valve from the pipe, minimizing downtime and simplifying maintenance procedures.
