This three-way ball sector valve (photo) — said to be the world’s first — achieves high volumetric flowrates that are virtually identical in all directions. The company’s approach of using the ball sector design for three-way valves is said to be completely new, and achieves about 20% higher Kvs values than three-way valves with a conventional design. These high flowrates are achieved through the special design of the ball sector and the valve body. The resulting straight flow in one direction and the minimized flow deflection in the other result in the very high and almost identical Kvs values. Superior control accuracy is ensured by the optimized contour of the ball sector and its backlash-free bearing, together with the actuator and positioner. The positioning angle of 90 deg enables a very large control range to be achieved. The rangeability is 300:1. — Schubert & Salzer Control Systems GmbH, Ingolstadt, Germany
