Introduction

Heldon’s magnetic check valve uses magnetic attraction to return the valve plate to its seat rather than spring pressure. A conventional check valve requires an increase in pressure to force the valve plate off its seat leading to an increase in pressure drop. Heldon’s magnetic check valve has a decreasing force to move it away from its seat. The further it travels the magnetic attraction diminishes leading to a decrease in pressure drop. Magnetic check valves are therefore a more efficient option to conventional check valves.

Heldon’s MCV uses the latest technology in DuraForm processing, a manufacturing method that eliminates the use of braze materials that can overheat and damage internal components. The body is 100% copper that has been spun into shape and the connections machined. The result is a valve that is hermetically sealed, can easily be installed with soft or hard solder, with a near zero leak rate and exceptional performance.

Suitable for Liquid, Suction and Hot Gas lines with all fluorinated refrigerants these valves are ideal in a new installation or as a replacement for of a conventional check valve.
