The 599 Series Two-way Ball Valves are coupled with OpenAir™ actuators to provide
equal percentage flow control. The ball valves are 1/4-turn rotary control valves and are
available in 1/2-inch to 2-inch line sizes.

Features
Application
• 200 psi close-off with ANSI Class IV leakage for all line sizes and actuators.
• Available with chrome-plated brass ball and brass stem or
stainless steel ball and stem.
• Blow-out proof stem withstands high pressure.
• Universal mounting plate.
• Actuator and plate can be rotated (90 degree increments).
• Standoffs provide a thermal barrier between the actuator and the mounting plate.
• Operating handle for manual operation.
Ball valves can control hot or chilled water and up to 50% water-glycol solution in
convectors, fan coil units, unit conditioners, radiators, and reheat coils.
WARNING:
CAUTION:
Personal injury/loss of life may occur if you do not perform a
procedure as specified.
Equipment damage may occur if you do not perform a
