Flow Control Valve has stepping motor actuator.
Press Release Summary:
Co-ax® flow control valve has solid-state ultrasonic position transducer with closed-loop control and stepping motor for control of fluids and gases at pressures up to 400 bar. Pressure balanced valve allows use of smaller, lighter electric stepping motors, reducing energy consumption, while decreasing response time. Valve is available with body for inline installation, or cartridge for installation into manifolds.
Original Press Release:
Co-Ax® Flow Control Valves Employ Two Precise Positioning Technologies To Control The Final Flow Element:
- a very precise stepping motor, or
- a solid-state ultrasonic position transducer with closed-loop control.
Penndel, PA June 2002 - co-ax® flow control valves are built using our proven co-axial technology, which means pressure balancing, positive shutoff, and above all dependability (designed and built for high cycle life).
Stepping motor control eliminates the need for compressed actuation air. Conventional flow control valves require compressed air because of the need to overcome forces caused by imbalanced control elements. Our pressure balanced design allows for the use of smaller, lighter electric stepping motors, reducing energy consumption, while decreasing response time.
Control via position transducer allows precise flow control of fluids and gases at pressures up to 400 bar.
They are available complete with body for inline installation, or cartridge versions for installation into space saving manifolds.
Typical applications
Metering / dosing
Dispensing
Batching / blending
Filling / purging gas cylinders
