1. Body
Attained by hot stamping or turned from solid bar, the body of the valve constitutes the external casing of the safety device.
Bodies are available in different sizes and surface finishes, supplied with the “Made in Italy” mark, a symbol of the highest quality
standards, reliability and Italian excellence. Ritmonio guarantees utmost quality of raw materials used and full observance of applicable
standards.
2. FLOW CONTROL DEVICES
The flow control device allows the water to flow from the feeding conduits into the water heater while limiting or preventing the backflow. Starting from the selection of materials, flow control devices can be customised according to customers’ needs.
Stand-by position
Flow control device in stand-by position.
Water heating supply position
It allows water to flow from the network to the water heater whenever there is a drop in pressure therein of 0.1 bar (0.01 Mpa).
Back flow position towards the network
It allows hot water to flow back into the feeding pipes whenever the differential pressure between the inside of the water heater and the network exceeds 1 bar (0.1 Mpa).
In any case, the water is guaranteed to flow back into the feeding pipes due to differential pressure exceeding 2 bar (0.2 Mpa).

3. PRESSURE SAFETY DEVICES
Constant research and innovation allows Ritmonio to offer high performing products. Our safety devices limit the increase in pressure inside the water heater when reaching the predefined calibration value in the safest and most efficient manner possible. During the assembly phase, the values are calibrated and checked using an automated system before the packaging phase. In this manner, high quality standards can be met which have always distinguished Ritmonio’s products worldwide.
