ASCO™ Series 615 Servotronic Digital Valve
The ASCO Series 615 Servotronic Digital is a highly dynamic 3-way proportional valve with digital control that is designed for applications with constant air or neutral gas flow.
The combination of innovative pneumatic technology, high-precision mechanics, and modern electronics allows for quick control of pressure in relation to a signal received from the controlling electronics. The valve is provided with a precision-lapped steel spool and sleeve with a hardened and tempered surface enabling very high pulse frequencies and extremely short response times. Control loop parameters are easily configured and optimized for specific customer requirements using Numatics Data Acquisition Software (DaS) and a PC connection.
