Selecting a MagnaValve ® and Controller

Make your selection of a magnavalve based on the type of shot peening machine you are using:
AIR BLAST or WHEEL BLAST

Why a MagnaValve?

The MagnaValve gives your shot peening process the edge you need in today's quality-driven markets. It eliminates guessing and provides reliable, repetitive, and consistent peening so you can be confident that you will always have the proper media flow rate. And because the MagnValve lets you document flow rate, you can record the data for a SPC program and quickly and easily establish or repeat a good set-up.

What is a MagnaValve?

A MagnaValve, invented by Electronics Inc in 1983, is a magnetic valve that will regulate the flow of steel shot used in abrasive blast cleaning or shot peening applications. The valve has a permanent magnet that stops the shot flow and also an electromagnet that allows the shot to flow by canceling the permanent magnet. There are no moving parts in the MagnaValve so there is nothing to break or wear-out. MagnaValves are used worldwide on wheel-type (also called turbine type in Europe) shot blasters and also on air type machines.
The MagnaValves used on air type machines have a built-in sensor to show the actual shot flow rate in pounds/minute or Kg/minute. The MagnaValves for wheel blast machines may be used with amperage control (i.e. no built-in sensor) or flow control using a built-in sensor.
MagnaValves work with cast steel shot and grit, cut wire shot and stainless steel cut wire shot. The valves will NOT work with stainless steel cast shot (also called Amacast from Ervin Industries).

24 Vdc power now available!

The entire MagnaValve product line is now available to operate with 24 Vdc power. This is in keeping with the world-wide trend of lower voltage for safety. It also helps us reduce the size and weight of our products allowing the controls to fit into smaller electrical cabinets. Many of the MagnaValves can operate directly with a customer's computer without the need our special controls. The computer must have analog signal capability with servo software.
