TriBloc

The TriBloc is a compact safety group for heating systems. It combines different functions in a single valve: bleeding, ventilation, pressure indication and pressure reduction by blowing. Expansion vessels or fill/drain valves can be directly connected to the TriBloc.

Description

  • Continuous and automatic bleeding and ventilation with the TacoVent HyVent
  • Pressure indication
  • Release of excess pressure

Advantages

  • Four functions combined in one valve
  • Connections of components self-sealing
  • Manometer and TacoVent HyVent with automatic locking system
  • Connection provided for expansion vessel or fill/drain valve
  • Extremely compact
  • Safety valve (TÜV-approved), rotatable
  • Manometer can be mounted at front or side
  • Valve group installed and inspected as ready to use

Functions

  • In this safety group, a float-controlled valve opens with increasing air volume to continuously release the air collected in the vessel
  • A connection channel routes the water and air smoothly into the air chamber
  • Pressure levels are indicated on the manometer and excess pressure is released through the safety valve (systems can be ventilated during emptying)

Technical Data

  • Operating temperature TO max: 100 °C
  • Operating pressure PO max: 10 bar
  • Response pressure: 2.5 bar or 3 bar (depending on model)
  • For heating systems up to 50 kW (as per DIN 4751)
  • Additional connections. ¾" AG and ½" IG

Materials

  • Valve-and-fittings support, TacoVent HyVent, safety valve: brass
  • Valve spring: stainless steel
  • Membrane: elastomer

Flow Media

  • Heating water (VDI 2035; SWKI BT 102-01; ÖNORM H 5195–1)

Applications

  • Safety valve and accessories group for heating systems in the power range up to 50 kW (DIN 4751)
