Clippard SCPV Cartridge & Manifold Configurations

Clippard SCPV Stepper-Controlled Needle Valves

Utilizing the industry's most robust and powerful linear actuator, the high-flow stepper-controlled proportional valves outperform the competition in performance and durability.

This valve is ideal in critical applications such as gas delivery, medical, analytical, and industrial automation requiring high resolution, high flow, and low hysteresis. In addition, the unique design allows for custom flow profiles when required.

• 2% hysteresis
• Excellent Linearity—2.5% of full-scale
• 2 ms reaction time
• Millions of cycles
• Holds position for power savings or at loss of power
• In-line, manifold and cartridge styles available

Control Data

A Bipolar Chopper Drive (not included) is a power-efficient method of using current to drive a stepping motor to obtain high stepping rates. The chopper gets its name from the technique of rapidly turning the output voltage on and off (chopping) to control motor current.

Stepper motors require some external electrical components in order to operate. These components typically include a power supply, logic sequencer switching components and a clock pulse source to determine the step rate. Many commercially available drives have integrated these components into a complete package.
