TacoSetter Rondo

TacoSetter Rondo saves on space and impresses with its functional design. It is suitable for direct installation in the flow or return directions of radiators or manifold bars, and enables uncomplicated adjustment of the volume flow without valve tables. With a measuring and control range of 0.6 – 8 l/min it has been designed for systems with small pipe dimensions. No tools are required for the adjustment and subsequent securing of the valves and accessories with a cover.

Description

Direct hydraulic balancing and control of flows to consumers. Balancing valves offer a quick, easy and accurate method of adjusting the flow rates through heating, ventilating and air conditioning systems.
Correct balancing of hydraulic circuits allows for lower flow temperatures, resulting in more efficient and economical operation in accordance with the energy saving regulations provided for by legislation.
With TacoSetter Rondo balancing valves, any qualified fitter can set the appropriate water distribution, thus avoiding investments in training and costly measuring devices.

Advantages

  • Accurate and quick balancing without diagrams, tables or measuring devices
  • The flow rate is displayed directly in l/min
  • Variable installation position, maintenance-free, compact
  • Regulating valve with isolating facility (rest leakage possible)
  • Self-sealing screw connector
  • Valve adjustment tool integrated in protective cover

Functions

The flow measurement is based on the displacement principle of a baffle disk, which is inserted in a measuring tube. The movement of the baffle disc is transformed to the sight glass by a mechanical device. The scale printed on the sight glass allows the flow rate to be read with ease.
Turning the sight glass changes the opening profile of the valve and allows the desired flow rate to be set.
