Swing Check Valve

Standard or Nonstandard : Standard Structure : Check Pressure : # 150 - 2500 ( PN 16-420) Power : Manual or Actuated Material : Carbon, Stainless, Alloy Temperature of Media: Any temperature class Media : Oil, Gas, Water, Steam, Acids Port Size : Any port size Place of Origin : Western Europe, Japan, USA, China Brand Name : KITZ, GLT, CRANE, WKM, CRA flexible solid stem: Bolted cap Internally mounted hinge: Ends RF, RTJ or BW Low fugitive emissions control: On demand: DIN gate valves Specifications : API 600 603 Check valves are generally used to protect pumps or similar equipment, preventing back flows. ANSI DIN Swing & Piston Check Valves Check valves are generally used to protect pumps, since they allow the flow only in one direction and prevent flow reversal due to back pressures. Swing type check valves, the most common type of check valves, are designed to produce a low pressure drop in the pipeline. They provide a tight seal as well as a fast closing reaction in case of back-flow. Compared to API600 design, widely used in process and petrochemical applications, API603 valves have high corrosion resistancy and find wider application within the food and fine chemicals industries.
