The 1gw Sena Va30 ball water valve is ideal for use in boilers, as it provides reliable and safe drainage and ventilation. This safety valve meets the requirements of a central heating system, helping to protect against overpressure. When the pressure exceeds a certain limit, the valve automatically opens, relieving the system and ensuring safety. The valve is double-port, meaning it has two ports, one for the medium's inlet and one for the outlet. Its operation is simple: when the inlet is closed, the flow is interrupted, and when it is open, the inlet and outlet flows are equal. Its construction from stainless steel ensures durability and long-term use, making it the perfect choice for your installation.
