Description

Swing check valve to DIN/EN with flanged ends (AKR) or butt weld ends (AKRS), pressure seal design, internally mounted hinge pin, body of forged and welded construction, seat/disc interface made of wear and corrosion resistant 17 % chrome steel or Stellite. Benefits Added safety due to pressure seal design providing increased sealing to atmosphere: The higher the pressure in the valve body, the tighter the cover joint. Very low risk of leakage, particularly at high pressures and temperatures. Compact design. Reliable, tight shut-off and service-friendly design due to flexibly mounted valve disc. Precise alignment of valve disc with body seat; valve disc is easy to replace. Hard-faced seat/disc interface made of wear-resistant and corrosion-proof 17 % chrome steel or Stellite for long service life and high functional reliability.
