 | | Unique 7000 Series - Long Stroke |
General Information The Unique 7000 Series is an innovative new generation of Tri-Clover® single seat valves that are designed to meet the highest process demands of hygiene and safety. They’re built on a well-proven, platform from an installed base of more than one million valves. Application The Unique 7000 is a sanitary air-operated seat valve with a flexible design. It can be configured as a shut-off valve with two or three ports or as a change-over valve with three to five ports. It’s ideal applications include the dairy, beverage, brewery, food, pharmaceutical, biotechnology and personal care industries. This long stroke version is specially designed for applications where suspended solids or high viscosity products are processed. Working principle The valve is remote-controlled by means of compressed air. It has few and simple moveable parts which results in a very reliable valve and low maintenance costs. Standard Design The Unique 7000 valve is designed to deliver years of reliability and performance 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 CIP capabilities and hygiene comes standard with all Unique 7000 series valves. For added confidence, the valve can be supplied with a controlled compression elastomer seat ring. The actuator comes with a five year warranty. The Unique 7000 Long Stroke valve sizes range from 1½" to 4". Other valves in the same basic design - - Standard single seat valve
- - Reverse acting valve
- - Aseptic valve
- - Manually operated valve
