BUTTERFLY VALVES

InterApp Butterfly valves are widely used all over the world, primarily due to the high quality of workmanship, which is confirmed by the sealing tests of each valve produced.

The production program includes 11 different types of butterfly valves:

• Butterfly valve with Teflon (PTFE) liner (Bianca) – centric valve produced in nominal sizes from DN25 - DN1600, suitable for ultra clean applications and highly corrosive fluids at pressures up to 16 bar. Beside Teflon, the seal can be made of Ultraflon, Ultraflon conductive, Ultralene, etc. The disc itself is made of stainless steel mechanically polished to Ra <0.8 or electropolished to Ra <0.4, or stainless steel coated with Hastelloy, Duplex, PFA, etc. The body of this model, as well as most of the models in offer, can be made in three shapes Wafer, Lug and U-section;

• Plastic butterfly valve (FEOV, FKO) – with elastomer liner is used for water and harmless fluids to which the material is resistant.




FEOV is a centric PVC butterfly valve, and and is made in nominal sizes of DN 40-200. The liner can be made of EPDM or Viton (FPM) material. Operating temperature from 0 - 60 ° C.









FKO is centric PP butterfly valve which is made in nominal sizes of DN 40-400. The seal can be made of EPDM or Viton (FPM) material. Operating temperature from 0 - 100 ° C.

CHECK VALVES

Check valves allow fluid flow in only one direction and have a protective function, protecting other valves and pumps from hydraulic shock. The company InterApp offers Disco, Swing, Dual Plate and non-return valves with a ball.


They prevent fluid backflow in the event of a pump failure:
