OMAL BUTTERFLY VALVE

OMAL butterfly valves, available in wafer or lug version from DN 40 to DN 600 (lug DN 300),  are designed and manufactured to be used in most applications in all industrial fields.

- General requirements in accordance with UNI EN593

- Face to face as per EN 558 series 20

- Tightness at 16 bar according to EN 12266-1 rate A

- Integral sealing (with liner vulcanized on hard ring) which avoids any contact between fluid and valve body.

- Sealing design allowing perfect adherence to the valve body and perfect tightness to the flanges, without additional parts. Clamping between flanges does not

  influence the torque of the valve.

- Improved disc shape which allows better tightness, reduced torque and low wear of the liner

- PTFE bushes to support the shaft

- Coupling between stem and disc with two shafts (better Kv) carried out with no additional fittings (e.g. screws, bolts, pins, etc.) to avoid any risk of corrosion and

  breaking

- Valve neck with top work as per EN ISO 5211 for easy connections with all different types of actuators

- All components properly treated against corrosion

OMAL will be free to change all specifications and data included in  this catalougue at any time, so as to improve the quality and the performance of its products.
