ANSI Standard 150LB-1500LB Cast Steel Stainless Steel Swing Type Forged Check Valve
Product introduction:
Check valve also known as automatic safety mechanism called a is used to allow fluids and gases to flow in one direction while preventing reverse flow. These valves seal tightly to stop leaks and guarantee that gases or liquids are flowing in the proper direction and prevents major harm to pumps and compressors by regulating the flow of liquids.
The body and bonnet of the check valve are made from forged steel. The bonnet is a removable cover that allows access to the internal components for maintenance or repair,It enhance valve’s strength and durability. The use of forged steel in the construction of these valves provides enhanced strength and durability, provides several benefits, including increased strength, durability, and resistance to corrosion. Forged steel check valves are commonly used in applications where high pressure and temperature conditions are present, such as in industrial processes, oil and gas, and chemical plants.
