Numatics Introduces 503 Series High Flow Rate Directional Control Valves
NOVI, MICHIGAN, USA, November 13, 2012 — ASCO Numatics, the world’s
leading manufacturer of comprehensive fluid automation, flow control, and pneumatics
solutions, has introduced the 503 Series of pneumatic directional control valves
with ultra-high flow ratings. The valves are designed for automation and piloting
applications across a wide range of automotive and tire, food and beverage, pharmaceutical,
packaging equipment, and general machinery applications.
”503 Series valves deliver the industry’s highest flow rates per valve
size. This enables design and specifying engineers to use smaller, lower-cost valves
and components that do more work with less air, energy, and cost,” said Robert
W. Kemple, Jr., executive vice president, sales and marketing — Americas, ASCO Numatics.
“In addition, designers can choose to generate greater speed of motion for
their components using the same size valve.”
This new valve line is available in either spool-and-sleeve or rubber seal models,
and proprietary or ISO versions to meet a wide variety of applications. “Our
unique dual-spool technology means customers get the highly reliable drive train
they need with the highest flow rates — increasing throughput and reducing maintenance
costs,” said Kemple.
503 Series valves are designed to complement the benefits of Numatics’ G3 fieldbus
electronics. When assembled together, original equipment manufacturers can leverage
assemblies that combine ultra-high flow rates with ease of use, plus fieldbus technology
that provides configurability, flexibility, and cost-effective I/O and distribution
