TILTING TYPE CHECK VALVE

– Short body, small volume and light weight

– Shafts protrude on both sides of the body and allow the lever and

counter  weight to be mounted on the right or left side, both vertical

and horizontal pipeline applications.

– Disc swings freely. The disc opening depends on the flow velocity

– Adjustable weight offers the adaptability to the individual working

conditions.

– Metal to metal or resilient seating options.

– Maintenance free design.

SLANTED SEAT CHECK VALVES

– These check valves can be used in all non-return applications.

– Better closing characteristics due to the smaller swing angle
    of the music.
– Closing time is reduced compared to the other check valve types.
– Because of non-extended shaft design, no sealing friction at
   the shafts.
– No lever and counter weight requirement. Thus dangerous
  movement of external parts is eliminated.
– Metal to metal or resilient seating options.
– Maintenance free design.

TILTING TYPE CHECK VALVES WITH HYDRAULIC DAMPER

– Tilting Disc Check Valves With Hydraulic Damper eliminate the

closing slams and water hammer for entire closing stroke.

– Closing speed is adjustable depends on working conditions.

– All components of the valves are designed for high stress occurred

during damping effect.

SLANTED SEAT CHECK VALVE WITH HYDRAULIC DAMPER

– On request Slanted Seat Check Valves are equipped with hydraulic
   end stage dampers in order to prevent the water hammer in
   pumping stations.
– The end stage damper is active at the last %10 of closing stroke.
– In case of power failure at the pumping station the disc closes very
   fast until reaching the damper that is why the back flow passing
   through the check valve during closure is minimum.
– This type is one of the best check valves then the turning back of
   pump’s impeller is critical. Damping effect can be adjusted by the
   help of integrated needle valve on damper according to the pumping
   and  working conditions.
– The end stage damper is not linked to the disc and does not resist to
.  open that is why headless of this type is less than the types with the
.  dampers linked to the levers.

AXIAL SILENT CHECK VALVES

– Short body, small volume and light weight.

– Because of low weight of moving parts and non-eccentric

design less shock long service life

– Suitable for high flow velocities.

– Drop tight sealing
