Flypass Valves

Flypass is a pre-assembled valve arrangement ideal for all your FCU installations. Plus it enables easy flushing of the system.

Economical, reliable and convenient

A Flypass valve incorporates:

  • Y-Strainer
  • Balancing valve (DRV or PICV type)
  • 2 x 3-way ball valves for flushing/isolation
  • Test points.

 

3 key reasons why other contractors continually use Flypass versus conventional methods:

  1. Reduces install time on site.
  2. Facilitates faster flushing/commissioning on site.
  3. Substantially more compact.

Unique to the Oventrop Flypass product is its compact design and complete elimination for any dead spots to occur. It is versatility suits almost any piping connection system, and allows for most brands of actuators to be used.

The Oventrop connection fitting “Flypass 4TZ” is used for the connection of fan
convectors (fan coil units), chilled ceiling modules, induction air systems, cooling and
heating zones etc. to the pipework of central heating and cooling systems with closed
circuit. The direction of flow is optional.
The connection fitting can be installed in any position (horizontal, oblique or vertical,
in ascending and descending sections). The ball positions and thus the flow
directions of the three-way balls are displayed by the shape of the handle.

Case Study

Royal Australian College of Physicians

This charming heritage building nestled between more modern 1970s style structures and stands as a monument to Sydney early Macquarie era days. Originally used as a newspaper printing facility, it is now the home to RACP. This is where overseas medical professionals come to validate their overseas training and gain Australian recognition. In July 2016 an upgrade to their existing chilled water system was approved, and the work finished in July 2018.
