Purged lip sealing valve (PLSV) Patent pending
The most reliable and durable valve
Our patent-pending purged lip sealing valve (PLSV) is a disruptive analytical valve that offers the best of both worlds: a longer lifetime than a diaphragm valve along with the constant pressure drop and simplicity of a conical rotary valve.
Designed to meet our high standards, this revolutionary technology is based on an innovative purge system as well as the valve insert’s reduced sealing surface area that replaces the traditional rotor. By design, it’s impossible for this valve to develop a cross-port leak.
