high pressure butterfly valve
Featuring a sturdy construction with high-strength materials, this butterfly valve provides a cost-effective solution for handling gases, liquids, and steam in industrial operations. It offers a reliable alternative to traditional gate or ball valves, delivering fast actuation, minimal pressure drop, and long service life.
Advantages and features
-
Designed for High-Pressure Applications：Unlike standard butterfly valves, this high-pressure variant is built to withstand extreme pressure conditions, making it suitable for demanding industrial applications where safety and durability are paramount.
-
Robust Construction with Premium Materials：This valve offers excellent corrosion and wear resistance. The materials are selected to endure aggressive media and harsh operating conditions.
-
Advanced Sealing Technology：Equipped with a metal or resilient sealing system, the High Pressure Butterfly Valve ensures a tight shut-off to prevent leakage. The seals are designed to perform efficiently even under extreme temperatures and pressure fluctuations.
Technical Parameters
| Order code | Model | DN | Valve opening angle flow cv value | |
| 90° | 70° | |||
| 18223 | DFR-01-50 | 50 | 135 | 90 |
| 18224 | DFR-01-65 | 65 | 220 | 144 |
| 18225 | DFR-01-80 | 80 | 302 | 183 |
| 18226 | DFR-01-100 | 100 | 600 | 364 |
| Note: When the valve uses switch control, Cv is selected when it opens at 90°; when the valve uses analog control, Cv is selected when it opens at 70°. The recommended control angle is 25°~70°, and the optimal control angle is 60°~65°. | ||||
