SensoGate® WA 131 - Van London

Pneumatic retractable fitting for simple commercially available control units or process applications.

Based on the proven SensoGate® modular design principle, the WA 131 retractable fitting is ideal for applications which do not require completely automated control with central media routing but which still want to make use of superior SensoGate® technology.
SensoGate® WA 131 is ideal for automatic or semi-automatic connections to commercially available or customer developed control units.
