Description
Pneumatic Triple Offset Butterfly Valves
Introducing the Triple Offset Pneumatic Butterfly Valve, the perfect solution for reliable and efficient flow control in various industrial applications. This high-performance valve is designed with a triple offset disc that ensures bubble-tight shut-off and eliminates any rubbing between the disc and seal, minimizing wear and tear and extending the valve’s lifespan. Additionally, the pneumatic actuator provides precise and responsive control, allowing for fast and accurate adjustments in high-pressure and high-temperature systems. The valve body is constructed with robust materials, providing excellent durability and corrosion resistance even in harsh environments. With its low-maintenance design and easy installation, the Offset Pneumatic Butterfly Valve is an ideal choice for oil and gas, chemical processing, power generation, and other demanding industries where reliability and efficiency are paramount.
GENERAL INFORMATION
Flanged triple offset butterfly valves provides zero leakage through no-rubbing 90-degree rotation across a wide range of pressure and temperature conditions.
Widely used in many industries such as Oil & Gas, Chemical & coal, petrochemical, desalination plants, waterworks, fossils, district heating, nuclear, Iron & Steel, Mining, automotive, shipyards, aerospace.
FEATURES Triple Offset Butterfly Valves
- ISO 5211 bracket for easy mounting of actuators
- Triple offset and ellipsoidal sealing geometry
- Bubble tight shut-off
- Inherently firesafe by design
- A metal seal ring in Duplex and a highly wear-resistant Stellite grade 21 seat ensure prolonged superior tightness
- Single piece cast body with face to face dimensions to ISO5752, ASME B16.10 and API 609 double flanged short pattern, guarantees interchangeability with other valve types
- Extensively hardened bearings, incorporating a standard reinforce, braided, flexible graphite bearing protector, ensure increased reliability
- Blowout proof devices on shaft keep sure safety of shaft operating
- Pin-less shaft to disc connection makes the valve convenient for parts replacement and reliable even under corrosion
