Georg Fischer 3519 Data Sheet

Signet 3519 Flow Wet-Tap Valve

Description

The Signet 3519 Flow Wet-Tap Valve
serves as a unique interface between
the installation fitting and the wet-tap
style Signet 515 or 2536 Rotor-X flow
sensor. It provides a fast method of
removing the sensor from the pipe
under specified operating pressures.
The PVC & stainless steel design of
the Wet-Tap makes it resistant to cor­rosion and chemical attack by acids,
alkalies, salt, and a number of other
harsh chemicals.

Assembly shown with

extended length flow

sensor installed.

The Signet 3519 Wet-Tap Valve
mounts directly onto standard Signet
installation fittings. The 3519 Wet­Tap consists of a flange and support
plate that threads onto the pipe fitting
insert, and a PVC ball valve through
which an extended length sensor is
inserted into the pipe.
