The function of the German standard swing check valve is to prevent the medium back in the pipeline, the pressure applied to the nominal is PN1.6-4.0MPa, the working temperature is of -20 ℃ -350 ℃ petroleum, chemicals, pharmaceuticals, fertilizers, power, various operating conditions of the pipeline industry and the like, or turn off the pipeline medium. The face-to-face length standard is DIN3202.

Swing Type Check Valves Flanged End VS Ball Typ
1. Material:
Both swing type check valves flanged end and ball type's material can be CI/DI/WCB/SS
2.Pressure
Both swing type check valves flanged end and ball type's pressure can be Class150/300/600/900, PN10/16/25/40/63,5K/10K/16K
3. Range of Applications (Difference):
Stardard: DIN 3202 PN10/16, ANSI CLASS 125/150
Face to face: DIN 3202 F1, MSS-SP-85
Connection flange type: Flange end
4. Installation (Difference):
Swing Type check valve overall no external leakage point, eliminate the possibility of valve leakage, suitable for cleaning medium, not for medium containing solid particles or with higher viscosity.
