Constructional Features

 

Body

Available in Wafer, Flanged, Mechanical Joint and Flange x Mechanical Joint End Connections in AWWA Classes 150B and 250LB.

 

Body Seat

360° uninterrupted body seat with no shaft penetration insures leak free performance. Type 304 Stainless Steel provides long life and corrosion free mating surface for resilient seat.

 

Ductile Iron Disc

Ductile Iron provides strength and rigidity to withstand dynamic forces from flow and pressure transients. The added strength allows the disc design to have a smaller cross section providing improved head loss characteristics.

 

Rubber Seat

Special formulated elastomers for chemical resistance and long cycle life. The 360° resilient seat is uninterrupted for positive seating.

 

Shaft

Stainless Steel shafts meet AWWA C504 diameter requirements. Through-shafts provided standard on sizes 3”- 24” and available on 30” and larger when specified.

 

Tangential Taper Pins

Stainless Steel Taper Pins with lock nut and o-ring seal utilize tangential forces of the taper pin and lock nut to provide the most secure method available of locking the disc to the shaft.

 

Traveling Nut Actuator

The traveling nut design provides characterized closure during the last half of travel. Exclusive externally adjustable stops are rated to 450 ftlbs of input torque. Standard FA10 motor mounting flange provides ease of automation.

 

Shaft Seal

Shaft seal is a self-adjusting/wear compensating V-Type packing. Packing is easily replaced without removal of the valve from the line.

 

Sleeve Bearings

Low friction bearings are self-lubricating and non-corrosive, for a long, trouble-free life.
