TacoSetter Bypass Solar

The TacoSetter Bypass, referred to in the branch as just «TacoSetter», is the classic model of balancing valves. The popular and reliable original for static hydronic balancing indicates the flow volume by means of a scale directly in a bypass test object or in the valve/accessories. The TacoSetter Bypass has been part of the Taconova portfolio since 1985. While retaining its trusted attributes, it has been continuously developed even further. Along with the standard version, there are also solar versions with greater temperature resistance (up to 185 °C).

Description

Direct hydraulic balancing and control of flows to consumers or in a subsystem. TacoSetter Bypass Solar 130 balancing valves offer an easy and accurate method of adjusting the flow rates for heating-, ventilation-, air conditioning- and cooling systems.
Correct balancing of hydraulic circuits ensures optimum energy distribution, resulting in more efficient and economical operation in accordance with the energy saving regulations provided for by legislation.
With TacoSetter Bypass Solar 130 balancing valves, any qualified fitter can set the appropriate flow rate using the unique flow measurement device, avoiding investments in training and costly measuring devices.

Advantages

  • Accurate and fast adjustment with scale and without the aid of diagrams, tables or measurement devices
  • Direct reading of the set volume flow in l/min
  • Temperature-resistant up to 130 °C
  • Variable installation position, maintenance-free
  • Flow control with setpoint adjuster
  • Regulating valve with isolating facility (rest leakage possible)
  • Minimal pressure loss

Functions

The flow measurement is based on the principle of a baffle float with return spring. The reading position is the bottom line of the baffle float.
The measuring device is placed in a bypass to the main flow, isolated from system flow. By demand the bypass, with self locking valves, gets opened / closed by pressing / releasing the clamp. Reading the flow rate has no influence on the main flow rate.
