General Description
The PDC Series 22 Combustion Valve is a cost effective, manual, wafer style butterfly valve designed for use in low pressure, low cycle ("set -and-forget") applications. It is designed for use in temperatures up to 900°F Maximum with differential pressures not to exceed 1 PSIG. The valve is designed with appropriate clearances in the disc for combustion installations. These applications are typically :"Hot" or "Cold" lines of air or combustible gases that require High-Low or Modulating flow control.
Features
- Lightweight, solid ring, wafer design for ease of installation. Four holes to insure proper alignment without transfer of pipe stresses to the valve body.
- PDC's Combination 10 Position/Infinite Throttling & Locking Lever Assembly offers both types of the most commonly requested manual actuators in one unit.
- Adjustable packing - Graphited TEFLON ® Braid for "Cold" (up to 450°F) applications - Graphited Glass Yarn Reinforced with Inconel Wire for "Hot" ( up to 900°F) applications.
- Valves can be repacked without removal from the line.
- Inboard bronze bushing on "Cold" (up to 450°F) applications and "metallized" carbon bushing on "Hot" (up to 900°F) applications are designed for long life, nonfreezing, low torque characteristics.
