PC3 Specifications
PC3 End User Features and Benefits:
• Low hysteresis throughout the range.• Excellent control, even at low flow settings.• Low power consumption.• Long, trouble-free life, tested to 100 million cycles.• Quiet operation.• Compact, 2-way, normally closed construction.• direct Acting: Functions from 25” Hg to 100 PSIg.• Made in the USA.• RoHS and REACH compliant.
The PC3 Miniature Proportional Valve is a compact, flexible solution for controlling air, vacuum, and some gases. Consult factory for fluids.
• Valve armature and body are plated to process a variety of media.
• All wetted surfaces are inert materials.• Tight sealing characteristics.
Typical PC3 applications:• Selectable, or dynamic control of media flow.• Control of downstream pressure.• Vacuum control applications.• Operation of small bore cylinders.
The Humphrey ProControl Series provides superior performance, versatility, and value. Utilizing a frictionless, flat-spring armature design, ProControl achieves excellent flow characteristics and long life in a simple, compact construction.
The PC3 miniature proportional valve is ideal for precise control up to 24 litres per minute. The inert construction makes the PC3 an ideal choice for many types of compressible media, including vacuum.
