ASCO Light Weight Miniature Solenoid Valve with Extended Life and Higher Flow

FLORHAM PARK, NEW JERSEY, USA, Oct 12, 2010 –- The ASCO 411 Series miniature solenoid valve offers up to twice the life of competing products plus higher flow rate performance. The 411 valve is ideal for applications in pharmaceutical, medical, analytical, and instrumentation products. 

“Now, original equipment manufacturers (OEM) can receive the benefits of longer life, smaller size, lighter weight, higher flow, and lower power consumption — all in one miniature solenoid valve,” said Robert W. Kemple, Jr., Executive Vice President, Sales and Marketing - Americas, ASCO Numatics. “The 411 Series dramatically reduces the design tradeoffs and compromises engineers must make in applying valves to their products.”

The 411 Series’ unique plunger design significantly reduces wear on the poppet and is resistant to internal elastomer swelling that can disrupt performance. The new valve has been tested to exceed 500 million cycles in normal operating conditions, making it the longest-lived, most reliable product of its kind on the market.

ASCO has increased the valve’s flow rate by up to 15% over previous models, and the maximum operating pressure differential has been improved. “These factors will enable engineers to design products with greater operating speeds, higher pressures, and smaller volumes,” said Kemple.

The new valve family incorporates a smaller, lighter weight plastic body that achieves up to 15% overall weight reduction when compared to stainless steel and brass-bodied valves. This makes the 411 Series a good choice for miniaturized and portable medical devices and pharmaceutical products. Lower power consumption means the valve also is attractive for use in battery-powered applications. In addition, it is the only miniature solenoid valve that is fully compliant with RoHS regulations.

“The 411 Series is assembled and tested in a specially built ISO Class 8 equivalent clean room that is dedicated to miniature solenoid valve production,” Kemple said. “Our valve’s exceptional reliability and its flexibility to address a wide range of specifications and operating characteristics provide the OEM with the widest variety of design options."

The 411 Series can be purchased from ASCO distributors or directly from the company. Many of the valve’s configurations are available through the ASCO Express 24-hour or ASCO 5Day shipping programs.
