Description
Check Valves:
non-return valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. The valve seat is closed either by mechanical means spring or by process fluid that the flow stream is blocked. The body cavity may be sealed by static seal. The seat can be sealed by o’ring seal.
Sanitary Valves
Valves are process components that provide dynamic seals within the process. Is a device that regulates, directs or controls 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.
