NEW: Low Pressure Industrial Regulators

4” / DN100 G1000 (Angled)

Application / Operation

As part of the wider G1000 family of products, the 4" (DN100) Dedicated Angled model is a low pressure, compact regulator for large commercial and industrial applications with excellent capacity capabilities.

The G1000 links accurate pressure control, reliability, high efficiency and sensitivity with maximum flow and minimum pressure loss and is designed for use with 1st, 2nd and 3rd family gases.

The new design is specified for use on U160 meter modules in IGEM/GM/6 and will resolve the issues related to the installation of unapproved smaller units causing pressure loss issues at the higher end of the capacity envelope. The unit can also be used in line with IGEM/GM/8 on higher capacity rotary meter applications offering benefits both in terms of a more compact configuration for the installation but also related time and labour savings.

The regulator can be designed to fit into a GC7+ Kiosk and as this Kiosk is normally used for U65 and U100 LP diaphragm meter modules, this rotary option gives much more capacity for the same size of housing. The unit has been tested in line with the requirements of 8.5.4 of GM/6 (inlet pressure conditions for a low pressure network) and has a demonstrated capacity of 320 m3/hr as a standalone regulator and as part of a meter module up to 235 m3/hr.

 

Features & Benefits

  1. Excellent capacity capabilities: Ensures wide range of metering applications
  2. Compact design: Ensures ease of installation and minimises kiosk/housing size requirements
  3. Lightweight: Lower unit weight than alternative solutions improving handling issues, saving transportation costs and reducing carbon footprint
  4. Quick response to rapid load changes
  5. Excellent outlet pressure control
  6. Internal impulse
