Diaphragm Valve Type 514 PVC-U Metric Solvent Socket PN10

  Datasheet.pdf

The Georg Fischer Type 514 diaphragm valve in PVC-U is a true union flow control unit built for demanding industrial piping. It carries metric solvent cement sockets from d16 mm to d63 mm and is rated PN10 (10 bar at 20 degrees Celsius), with a PN16 execution available as an option. Typical duties cover chemical processing, water treatment and the distribution of corrosive fluids, where the true union body allows radial installation and removal of the valve without disturbing the adjoining pipework.

Optimised internal hydrodynamics give the Type 514 double the flow rate of the predecessor design, cutting pressure loss along the line, while the linear flow characteristic supports repeatable throttling. The central housing union nut replaces the conventional four-screw bonnet assembly: this non-metallic fastening removes external metal corrosion risks, applies uniform sealing compression around the full diaphragm perimeter and shortens maintenance work. The ergonomic manual handwheel includes a built-in locking mechanism that holds the selected throttling position against operational vibration.

The body is moulded in dark grey unplasticised polyvinyl chloride (RAL 7011), delivering high chemical resistance to aggressive acids, alkalis and saline solutions. The short overall installation length eases integration into space-restricted skids and distribution manifolds, and the modular platform allows individual valve configuration, including a self-adjusting multifunctional module with integrated limit switches for electrical feedback.
