The Adjustable Purge Valve (APV) controls material flow from a hopper or surge bin, and is ideal for use with central drying and conveying systems.
The APV releases material into the conveying lines as needed, and then purges the material lines to prevent material cross-contamination and/or moisture regain.
The APV can be used in either dry or ambient air conveying applications.
Externally mounted Line Valves effectively stop the flow of material to vacuum receivers for trouble-free operation of common or single material line conveying systems.
At rest, the inlet is closed, allowing the valve to isolate the receiver from the common material line of central systems. When the vacuum sequence valve opens, the line valve allows material to fill the receiver.
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.
Conair Purge Valves provide an effective means of purging conveying lines of residue material between conveying sizes and material changes.
Each valve is equipped with a single outlet and dual inlets: one for material and one for air. When activated, the valve halts material flow, and then floods the conveying line with air to evacuate material.
