FEATURES

Shaft and Flange Seals

• Field replaceable, phenolic bonded cartridge seat provides no movement of the elastomer which is a common failure point of many resilient flexible seat designs.
• Torque fluctuation is eliminated by our phenolic bonded elastomer seats.
• Our dual purpose primary flange seal is widened offering additional compression of the elastomer against various flanges resulting in a positive seal.
• This resulting primary flange seal provides a smooth flow conduit for media and prevents build up in crevices created by traditional seat designs.
• Molded secondary flange seals assure no leakage when used with weld neck, slip on and threaded flanges and eliminates the need for gaskets or O-rings.

Shaft Sealing Method

• Disc shaft holes surrounded by a 360° machined radius are in constant contact with the flatted area of the seat.
• This design is far superior to resilient flexible seat designs that depend on the “squeeze” effect of the disc and seat interference which allows leakage behind the seat and up the shaft.
• The Flow Line shaft seal is achieved through a continuous pressure exerted from the flatted area of the seat to the machined radius of the disc.
• This sealing mechanism is further enhanced by forces exerted on the seat and shaft providing a secondary seal resulting in media free disc, shaft and seat connection.
