The main role of the Vacuum Pressure Relief Valves and Safety Valves deals with the guarantee of the highest safety in the plants, where there is the passage of fluids or gas. Varied models of valves are available, either in AISI304 or in AISI 316. They do have a wide use in the food-, pharmaceutical, chemical and oil-naval sector.
Vacuum Pressure Relief Valves
The vacuum pressure relief valves allow the discharge of air from the conduits in pressure, in order to guarantee the regularity of the water flow. This typology of valves is used in order to prevent problems inside the pipes, such as the reduction of the flow rate.
The relief valve is characterised by various functions, such as the entry of big volumes of air, in order to compensate for the liquid which comes out (preventing depressions), the air leak (avoiding the development of air pockets), and its elimination in the pipe.
The safety valves allow the plants, where there is the passage of liquids or gas, not to be submitted to a dangerous pressure, emptying the fluid when the calibration’s value is achieved. In order to guarantee the safety in the plants, it is very important to check these valves and their correct operation regularly.
