Description

The GF Signet 3-3719-21 (159 000 805) is a 2-inch NPT threaded pH/ORP wet-tap assembly designed for safe, in-line electrode maintenance without system shutdowns, suitable for DN150 to DN300 (6 to 12 in.) pipes. Key features include the SafeLoc™ cam-activated lock, sealed pneumatic dampening for safety, and a 45 mm (1.75 in.) short-stroke design. The GF Signet 3-3719-21 (159000805) is a 2-inch NPT Wet-Tap assembly designed for installing and removing pH or ORP electrodes in pressurized pipes (6 to 12 inches) without requiring a process shutdown. It is specifically used with DryLoc® electrodes for continuous monitoring in various liquid process applications.The GF Signet 3-3719-21 (159000805) is a CPVC pH/ORP wet-tap assembly featuring a 2-inch NPT process connection, designed for 6 to 12-inch pipes. It enables sensor maintenance without process shutdown, operating at up to 100 psi (6.9 bar) and featuring SafeLoc™ for safety.

The Signet 3719 pH/ORP Wet-Tap allows installation and removal of pH or ORP electrodes, even under process pressure, without the need for process shutdown during routine electrode maintenance and calibration. Process isolation is achieved during electrode retraction with two sets of double O-ring seals on a unique and compact retraction assembly; no separate valve is required. The Wet -Tap body design allows full access to the plunger and internal O-rings, to easily perform maintenance such as lubrication/replacement of O-rings and the cleaning of the internal plunger/housing to remove material build up in diffi cult applications. A patented cam-activated automatic locking mechanism, SafeLoc™, and the short stroke design help to assure operator safety. The wet-tap unit can be mounted at any angle and can be used with the Signet DryLoc® Wet-Tap electrodes.
