680 Vector Module™ For Below Ground Installations
Introduction
A Measure of Control for the Gas Industry Containing all the elements required for a conventional gas pressure reducing station. For use on gas distribution systems, the module is designed for below ground installation, this simplifies planning by limiting the need for mains diversion. Above ground is a ‘Vent Stack’, which contains vent pipes for atmospheric reference pressure and relief valve. Alternative vent stacks are available to accommodate various types of instrumentation, pressure recording or control systems
Take a look at these benefits:5 Compact Design, with all control elements contained within underground housing 5 All equipment is of standard design and cartridge type for ease of maintenance 5 Separate Filter Chamber - allows removal of filter element without the need to remove the main control unit
5 High Performance - designed to accommodate low inlet pressure and minimal pressure differential. 5 Low Noise Levels 5 Easily adaptable to suit various types of control systems. e.g. Clocking, Profiling etc.
