Product description

DOUBLE OFFSET HIGH PERFORMANCE BUTTERFLY VALVES

ISO 5211 Mounting Flange
Designed to close mount a gear operator or actuator for easy installation.

Recessed Packing Gland
Allows for direct mounting of actuation and minimizes space required for installation.

Stem Seals
Cup & cone (chevron) PTFE or flat graphite for positive seal.
Extended Neck Allows for 2” of pipe insulation.

Body
Robust one piece casting in WCB
Carbon steel or CF8M stainless steel.

Available in wafer & lug style.
Positive Cast Disc
Position Stop
The position stop is machined in the body and locates the disc in
the seat. (not visible)

Seat Retainer
Reliable multi-bolt retainer holds and supports the seat in bi-directional flow. Made with the same material as the body.

End Cap Seal
Made of PTFE or graphite.

Thrust Ring
Centers the disc and ensures positive shut-off. Made of 316 SS.
Bearing (lower)
Full length provides maximum stem support.
Made of 316 SS/PTFE

Disc
The disc is designed for a quick release from the seat which reduces torque and seat wear. Standard material is 316 stainless steel.

Tangential Disc Pins
Offset from the axis of the stem, which places the pins in compression rather than in shear. This gives the taper pins a
yield point greater than the stem itself.
Made of 17-4 PH material. (not visible)

Seat
An advanced free floating, pressure assisted, solid seat design provides an interference and pressure assisted seal. This creates a positive seal under both low and high pressure requirements securely positioned by a seat retainer plate. The seat does not rely on any secondary components to hold it in place. This will allow for longer service life with less maintenance.

Bearing (upper)
Full length provides maximum stem support. Made of 316 SS/PTFE

Anti-Extrusion Ring (under stem seals)
Prevents the extrusion of stem seals,
maintaining optimum seal.

Stem (blowout proof)
Manufactured as a standard of 17-4 PH stainless steel to provide
maximum strength and stability for high torque applications. Designed per API 609 standards.
