The Dn20 3/4 Gw-Gw Sena Va30 Ball Water Valve with Inox Lever is specially designed for use in boilers and provides reliable operation in the central heating system. This safety valve ensures efficient depressurization of the system when the pressure exceeds preset limits, thus protecting people and materials from potential hazards. It is two-way, meaning it has two ports, one for inlet and one for outlet of the medium. When the inlet is closed, the flow is interrupted, while when it is open, the flow is equal on both ports.
