Resilient Seated Butterfly Valve-Features
 

• Separate Bushings: Ensure proper alignment of the shaft through the valve body and reduce operating torque.
• Blowout-Proof Design: The stem is fully retained by pins to the valve disc, preventing blowout and ensuring secure operation.
• Leakage Prevention: The stem is sealed by two separate O-rings and an integral seal in the seat, ensuring absolutely no external leakage throughout the valve's lifespan.
• Resilient Seat Surface: The replaceable seat extends past the valve face, eliminating the need for gaskets on flanged installations and significantly reducing installation time.
• Reduced Torque: Allows for the use of smaller, more economical actuators while still meeting close-off requirements.
