Check valves with full bore

We can 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
