GEA’s Y type Tube Selector Valves are flow diversion valves that employ an axially mounted plate to control the flow of pneumatically transported materials. Flow may be diverted to one of two tubes, which intersect at an angle of 22.5 degrees.
A Y-diverter is used in situations where a flap type valve is unsuitable due to high line pressures or abrasive materials. Y-diverters are ideally suited for full vacuum conveying systems or applications whereby leakage or product contamination is not acceptable. By using a number of valves in series, a complete multi-point discharge system can be developed. As well as being employed to divert one stream to one of two destinations, they can be reversed to converge two different stream sources to one common destination. Each valve has a precision-engineered internal bore to keep the transit velocity constant, maintaining a minimum pressure drop across the valve. A divert vane contained within the body of the valve redirects product down either branch.
