As manufacturer from valves for shipbuilding and industry we also offer check valves with full bore and short face-to-face.

Following designs of our 
check valves are available:
• with full bore
• short face-to-face
• extreme low drag coefficient (zeta)
• barely resitance to flow
• tight closing at low difference
• O-ring sealing (exchangeable)
• metal/metal-sealing on request
• after utilization the elasticity of
   O-ring remains tightness metal/metal
• maintenance free
• universal application for gaseous or liquid mediums in
   oil-, air-, gas- and water-systems also used in the chemical industry
• available in cast iron, nodular cast iron, bronze, gunmetal with
   flap material Al-bronze or stainless steel

Technical data:
• zeta values  ζ = 0,8
  (sandwich check valve  ζ = 3,75)
• nominal diameters DN 15 up to DN 300
• working pressures:
   DN   15 up to DN 150 PN16
   DN 200 up to DN 300 PN10
• working temperatures:
   NBR -40°C up to +100°C
   FKM -30°C up to +200°C
