Key Specifications / Features

This concentric butterfly valve combines a ductile iron GGG40 body with a full PTFE lining to deliver chemical resistance at a lower cost than solid alloy construction. Manufactured to API 609 standards, the 3-inch (DN80 / 80 mm) valve is rated for Class 150 LB and features a resilient seated design for bubble-tight shutoff across a wide range of corrosive and abrasive fluids. The wafer or lug configuration allows for easy installation.

Concentric Lining butterfly valve adopts lining on all the parts that contact with medium inside of body, the stainless steel which is resistance of corrosion is used as stem and disc to ensure the corrosion resistance of different strong corrosive medium. The valve body and disc materials can be made of cast iron, carbon steel or stainless steel to ensure the bearing strength. Many kinds of soft sealing material such as NBR, EPDM or PTFE etc can be used as lining material to adapt to different corrosive medium or working temperature.

Structural Features

» The indicator plate has multiple opening angles ranging to 90 degrees, which is convenient to locate the gate.

» Top flange as per ISO 5211 to allow for the easy installation of gear box and actuators.

» O-rings provide positive stem sealing performance.

» Note: Alternative packing solutions available.

» Dual stem design reduces valve operating torque.

» Upper and lower bearings minimize operating torque.

» The semi-circular butterfly plate design reduces operating torque and promotes extended service life. The seal ring is supported to achieve disassembly and prevent leakage of the seal ring.

» The seal ring extends to the end of the body and is installed without additional gaskets.
