Ratio Valve

Efficiently Combine Two Materials While Loading

Externally mounted Ratio Valves connect readily to Conair vacuum receivers and loaders equipped with ratio-capable controls.

The dual inlets alternately open and close in response to a timed control signal, providing a mix of virgin and regrind materials during each vacuum loading cycle.

At rest, the regrind side is open and the virgin inlet is closed, allowing the valve to isolate the receiver from the common material line of central systems.

Modular design

Screw-in components allow common wear parts to be easily replaced and line sizes to be changed without the need of purchasing another valve.

Smooth aluminum body

A non-corrosive, smooth path for material flow.

Easy to clean

Removable with no tools, the lid provides wide open access.


Dual solenoid

This special Ratio Valve option allows both material inlets to be normally closed for dual common material line operation.

High performance

The high performance Ratio Valve has stainless steel inlets and outlets, includes high temperature Viton seals in the pneumatic cylinders, specially plated and heat-treated valve body, lid and plungers for maximum wear resistance.

Ratio Valve as a material selector

A simple A/B toggle switch selects which material inlet is open, for easy selection between two material lines.(120V/1phase/60 @ 2 amps.)

Conair ratio control
Add ratio loading capability

Any 120 Volt single inlet loader may be converted to ratio operation with this control. The control uses the vacuum loading signal to create timed virgin and regrind signals.
