Product Overview and
Principle of Operation
MagnaValve® Description
The MagnaValve® WM 3000-24 is a normally closed valve that regulates the ow
of steel shot or grit in wheel-blast machines for blast cleaning applications. It is a
powerful valve with a ow rate capacity of up to 3,000 lb/min (1,361 kg/min) for
wheels up to 125 hp. The Remote Valve Driver for the MagnaValve comes with a 6-ft
cable for installation in the customer’s electrical panel, making it an ideal valve for
blast machines in high-temperature environments.
The MagnaValve reduces media usage, energy costs, machine downtime, and wear
and tear on equipment.
How It Works
The MagnaValve’s maintenance-free construction includes a rare earth permanent
magnet for normally closed operation and an electromagnet for controlling shot ow
rates. With power applied, the magnetic eld is neutralized and shot is allowed to
ow through the valve.When no power is applied to the MagnaValve, the permanent
magnet stops all ow. If the power is interrupted for any reason, the permanent
magnet securely holds the shot.
The MagnaValve is factory tested and results are supplied upon request.
MagnaValve Controllers for Closed-Loop Operation
For an “automatic” closed-loop operation, an Electronics Inc. AC-24 Controller will
detect the current load on the wheel motor and regulate the ow of media to the
WM 3000-24. The WM 3000-24 MagnaValve, with the AC-24 Controller, provides
reliable, repetitive, and consistent media ow rates for blast cleaning applications.
The MagnaValve system makes it easy to document ow rates and establish or repeat
a good set-up.

Installation
MagnaValve
The MagnaValve must be mounted in a vertical position with an adequate supply of
media above it.
Remote Valve Driver
The Remote Valve Driver should be mounted in an electrical panel that conforms to
the temperature range of 50˚- 120˚ F (10˚- 49˚ C).
Adjustments
MagnaValve
No adjustments are required or recommended. The valve has been tested at the
factory prior to shipment.
Remote Valve Driver
Adjustments to the Remote Valve Driver can be made from the front of the driver;
however, the factory settings should not be changed.The output signal is 10 Vdc. See
page 5 for additional information on the Remote Valve Driver.
Operation
MagnaValve
Signals used to operate the MagnaValve originate at the AC-24 Controller. There are
three conditions necessary for correct operation.
1) Power. 24 Vdc power must be continuously applied to the valve. The valve
requires 2 Amps for operation and a power supply rated at 50 Va. The voltage
should be 24 ±2 Vdc.
2) Enable Signal. The 24 Vdc Enable Signal is used to activate the valve.
3) Input Signal. The analog 0-10 Vdc input signal must be above 0.25 Vdc as a
minimum ow command signal.

*Diagnostic LEDs
Valve On. Indicates when power is being sent to the MagnaValve’s electromagnet. When the
LED is on, the valve is on for full capacity ow rate. When the LED is o, the MagnaValve’s
permanent magnet has stopped the media ow. When the LED is blinking, the shot ow is
being regulated.
Vin > 0.25 Vdc. Indicates that an analog signal input greater than 0.25 Vdc has been received.
When this LED is o, no media ow is allowed. The input signal range is 0 -10 Vdc. At 10 Vdc,
the MagnaValve will open to full capacity. The relationship between the 0 -10 Vdc input signal
and actual ow rate is non-linear.
24 Vdc Enable. Indicates that the 24 Vdc Enable Signal has been received. When the LED is
o, the MagnaValve is inhibited and no shot will ow. This feature is provided as an on-o
action so the 0-10 Vdc input signal does not have to be disabled or removed.
24 Vdc Power. Indicates that 24 Vdc is available to operate the electromagnet for media ow.
It should always be available and able to supply 2 Amps.
All four LEDs must be on in order to have media ow.
Diagnostic LEDs*
The large knurled screw on the front cover of the Remote Valve Driver can be removed to gain
access to the factory adjustments. Please refer all adjustments to qualied personnel.

Troubleshooting
If all of the LEDs are on but there is no media ow, please check the following:
1) Is the mechanical slide gate valve above the MagnaValve fully open?
2) Is media available from the hopper?
3) Is there a blockage above or below the MagnaValve?
4) Is the magnetic eld completely cancelled when the “Valve On” LED is on? Check this by
removing the valve from the machine and applying the proper signals for 100% ow. Did all
of the shot fall from the valve?
If the problem can’t be identied or if you detect a problem with the magnetic eld,
contact Electronics Inc. Please have the following information ready.
1) Number of valves on the machine ___________________________________
