What is the main function of safety valves?
Modern heating systems heat a constant volume of water and distribute it throughout the installation. The higher the temperature, the higher the pressure. Sometimes, this pressure can get too high and generate safety or operational problems. The main function of the safety valve is to avoid this happening – to prevent possible high-pressure hot water leaks or other accidents.
Next, we will show you the characteristics of our safety valves which are available in this section of the web.
Safety valve models from the Valfonta catalogue
- Progressive opening safety valves (figure 368-371)
- ALPER fully opening safety valves: detect excess pressure in tanks, boilers or pipes and automatically discharge excess fluid without using any auxiliary energy. Once the pressure is normalised, the safety valve closes. All are tested on the test bench with pressurised air at room temperature, and are supplied at the set pressure requested by the customer.
- ALPER atmospheric valves:they allow the passage of air into and out of watertight containers. They have a double spring, both to adjust the vacuum (negative pressure) and to adjust the positive pressure. Specially designed for very small pressure ranges. The outlet of the valve is protected by a stainless steel mesh to prevent the entry of impurities.
