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