Design Features

  • Inboard bushings of graphited bronze for long life, non-freezing, low torque characteristics on both shaft ends.
  • Close tolerance machining for minimal leakage and dependable flow characteristics.
  • Adjustable packing-Graphited TEFLON ® Braid. Valves can be repacked without removal from line on both shaft ends.
  • Rugged mounting pads drilled and tapped for ease of installing actuating equipment and accessories.
  • Flatted, keywayed or hexed ends on shafts are available to facilitate factory or field mounting of all types of actuating equipment. (Flatted shaft shown).
  • Lightweight, solid ring, wafer design for ease of installation. Four holes to insure proper alignment without transfer of pipe stresses to the valve body.

* “G” Length and configuration of the shaft end will vary to accommodate specific actuators. Refer to the accessory section for typical flatted, keywayed, and hexed end configurations available.

MAX. ∆P is based on 0° disc position, using standard materials of construction at a maximum temperature of 450° Fahrenheit.

Consult factory for MAX. ∆P for elevated temperatures.

Cv Values for PDC Swing Thru Butterfly Valves

By definition, Cv is the flow coefficient of a control device or flow restriction. Cv is defined as the number of US gallons of 60°F water per minute which will flow through the given restriction with a one pound per square inch pressure drop.

Cv Values

(Flow in GPM of 60°F water at 1 psi pressure drop, specific gravity=1)
