WORKING PRINCIPLE

The valve is remotely controlled by means of compressed air. The valve's parts are few, simple, and movable—which results in a very reliable valve with low maintenance cost.

STANDARD DESIGN

The Unique 7000 valve is designed to deliver the years of reliability and performance that you’ve come to expect with all Tri-Clover products. Its flexible design consists of either one or two bodies that are clamped together. The TR2 seat ring with enhanced hygiene and CIP capabilities comes standard with all Unique 7000 series valves. For added confidence, the valve can be supplied with a controlled compression elastomer seal ring. The standard actuator comes with a five year warranty. The Unique 7000 valve sizes range from 1 – 4 inches.

FEATURES
