Description
Relief valve:
The relief valve (RV) is a type of valve used to control or limit the pressure in a system or vessel which can build up for a process upset, instrument or equipment failure. Vacuum safety valves (or combined pressure/vacuum safety valves) are used to prevent a tank from collapsing while it is being emptied, or when cold rinse water is used after hot CIP (clean-in-place) or SIP (sterilization-in-place) procedures. When sizing a vacuum safety valve, the calculation method is not defined in any norm, particularly in the hot CIP / cold water scenario, but some manufacturers have developed sizing simulations.
Sanitary Valves
Valves are process components that provide dynamic seals within the process. They regulate, direct, or control the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. They also provide seals between the process and the atmosphere.
Keep Your Sanitary Fluid Operations Tight And Sealed
Sanitary pressure relief valves are suitable for use in the food, dairy, beverage, pharmaceutical and industrial markets, and are an important part of controlling the flow of your fluid product.
