Features

  • The sealing that can be made of EPDM, NBR and VITON materials can be dismantled and replaced easily on field conditions.
  • Inner and outer surfaces of the valve is coated with 300 microns thickness of fusion bonded epoxy.
  • Higher thicknesses are availabe upon request.
  • Hydraulic braked swing check valves prevent the occurrence of hard brakes due to the effect of the braking system and virtually eliminate the noise, ram impact and damage.
  • Ensures 100% sealing with the “T” section ring fixed to the outer diameter of the disc fully facing the seat surface inside the body perimeter made of stainless steel welding.
  • Low moments are obtained by decreasing the friction through self lubricating bushings.
  • Can bear high stretching stresses on the pipeline through the ductile iron body and disc.
  • High impact resistance.
  • Reduces the pressure loss through the disc designed in accordance with the direction of flow.
  • Pressure loss is at minimum level by double shaft design.
  • Countervalve allows installation of both horizontal and vertical pipes on the right and left sides of the mill, counterweight, and lever on both sides of the check valve.
  • The clapper opens depending on the flow rate and moves freely depending on the flow.
  • The position adjusts to the working conditions thanks to the adjustable weight.
  • Lifting lugs and feet ease the balance during transport and installation.
  • Hydraulic braked swing check valves prevent the occurrence of hard brakes due to the effect of the braking system and virtually eliminate the noise, ram impact and damage.
  • The closing speed can also be adjusted in accordance with the operating conditions in the swing check valves with hydraulic brake.
  • With the o-rings on the bearing bushings, disc pin holes are protected against corrosion (Dry shaft).
  • Retaining ring is assembled to the disc with imbus bolts, the disc is protected against corrosion by placing o-rings under the bolts.
  • Inner and outer surface of the valve is coated with minimum 300 micron thickness FBE coating.
