PROPORTIONAL CONTROL VALVES
“MASTER FLOW” PROPORTIONAL IN-LINE REGULATOR
FEATURES
• Combines PV1 with Master Flow regulator
• Compact size
• Minimal droop
• Piston operated for long life
• Self relieving
• In-line mounting
• Modular design for ease of maintenance
• Compact size to flow ratio
• Rugged anodized aluminum construction
• Optional pressure ranges available for specific
application (100 psi max.)
The proportional control valve is mounted to Alkon’s
own precision pilot operated regulator assembly.
Available in 1/2” and 3/4” NPT, it offers tremendously
high air flow capabilities (390 SCFM). With a precisionregulated
range of 5-100 psi (standard), it experiences
minimal hysteresis while maintaining exceptional
repeatability, sensitivity, and resolution. It is a rugged
compact design, easily mounted in-line for a multitude
of applications.

The industries first proportional regulation system designed specifically for
a directional valve. The AU1 and AU2 5-ported valve package covers 1/8” thru
3/4” port sizes with flows of 1.4 to 6.6 Cv . This unique Alkon design offers
no flow reduction with interposed regulation as do all other currently available
valve packages on the market today.
