A manual diaphragm valve that allows for safe and secure sampling.
The 650TL type safe sampling valve is used at sampling points and use points. It is a manual valve, but it can only be opened and closed when operating air is supplied; the valve remains closed when operating air is not supplied. Due to the air switching, it is possible to lock the handle remotely, allowing the timing of sampling at each site to be controlled by a central management system.
