Check valves with full bore

As manufacturer from valves for shipbuilding and industry we also offer check valves.

 

Following designs of our check valves are available:
• with full bore

• small face-to-face

• extreme low drag coefficient (zeta)

• barely resitance to flow

• tight closing at low difference pressure

• 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, steel 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

   PTFE -50°C up to +260°C

 

 

Of course, you can get also other types of our valves from our product range e.g. our butterfly valves, flanged swing check valves, sandwich check valve with or without spring, dual plate check valve.
