Asco Numatics introduced the new Sirai stepper motor pinch valves series S170/S370, offering high pinching strength and proportional and accurate control of the crushing of the tubing that controls the fluid. The pinch solenoid valves are equipped with an electric stepper motor combined with an electronic management board, allowing limited power consumption and helping reaching a pinching strength of 80N, enabling the valve to work with tubings with hardness up to 90 shore A.
The electronic board allows the valve to work in multiple configurations, especially in ON-OFF mode, proportional with adjustment potentiometer and with analog input 0-5 V or 4-20mA. The series is available for 12รท24V with electric connection Molex pitch 6 and 2 poles, and can be delivered already programmed and customized according to requested configuration, making installation easier and faster. In addition, the valves can also be supplied without the electronic board, in order to integrate them into an existing system.
