Expansion of the range of VALTEC control valves

New automatic differential pressure regulators VALTEC – VT.043, VT.044 are now on the market.

Such regulator is ideal for two-pipe systems equipped with thermostatic radiator valves. It automatically levels down pressure drop in case of reduction or termination of consumption by any serviced consumers, maintaining hydraulic stability of the system as a whole.

Regulators VT.043 and VT.044 render possible maintenance of the required (fixed in case of VT.044) differential pressure (ΔRn) between the regulator and the point of connection of the impulse tube, thus limiting the flow of the operating environment through the regulated section.

The main purpose of the regulators is combined action with VT.054 balancing valves in two-pipe heating systems. In this case, VT.054 balancing valve sets the design value of the connection differential pressure in the served circuit (ΔDc), while the design differential pressure in this section (ΔRn) is maintained by the differential pressure regulator (Fig. 1).

In case when use of the balancing valve is not required, it is recommended to connect the impulse tube to the ball valve with drainage and air vent valve VT.245 equipped which nozzles with 1/4 ” female thread (Fig. 2).
