The Crazy Fly One Pump 2018 safety valve is ideal for use in boilers and helps ensure the safety of the central heating system. It operates efficiently by protecting the system from excessive pressure. When the pressure exceeds the preset value, the valve opens automatically, allowing depressurization and reducing risks to people and materials. It is installed at the highest point of the installation and functions without the need for a switch or lever.

This valve is two-way, featuring two ports: one for inlet and one for outlet. When the inlet is closed, flow is interrupted, while when it is open, the flow at the outlet equals that at the inlet, ensuring effective operation.
