Carbon Steel Flanged 300LB Triple Offset Butterfly Valve for Gas
Carbon Steel Flanged 300LB Triple Offset Butterfly Valve for Gas
Product Features
Both the valve body and disc are made entirely of WCB carbon steel, meeting the structural requirements for steam, thermal oil, and petroleum products at a more economical cost. With a 300-lb pressure rating, it performs flawlessly in ”pressure-critical" applications such as boiler outlet and cracking gas shut-off points. The drive end features manual operation, allowing for forced opening and closing by manual labor during power outages or emergency power shutdowns, without increasing costs.
Product Advantages
● Compared to metal-seated ball valves of the same nominal diameter, the torque required for a triple-offset butterfly valve is less than one-third.
● The bolt assembly forms a closed load-bearing ring at the flange interface, dispersing and absorbing pipeline thrust, bending moments, and thermal expansion forces. This prevents the gasket from being subjected to off-axis tension, ensuring the sealing ring remains flat and free from warping over the long term.
● The all-metal sealing pair withstands fire exposure and meets API 607 fire-resistance requirements. In the event of a fire, it does not melt or rupture, providing the final line of defense to protect the pipeline.
