Type 3519 Flow Wet-Tap Valve

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 and 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.

The Signet 3519 Wet-Tap Valve mounts directly onto standard Signet installation fittings. The 3519 Wet-Tap 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.

  • Installs into pipe sizes: DN15 to DN900, 0.5 to 36 in
  • Material: PVC body, seals FKM or EPDM
  • Max Pressure rating: 7 bar @ 20 °C, (100 psi @ 68 °F)
