Colorflow Pressure Compensated Flow Controls
  Series PC (Pressure Compensated)

General Description
These valves are designed to regulate flow at a selected rate then maintain this flow constant within ±5% as inlet and outlet pressures may vary. However, changes in fluid temperature will prevent flow from holding constant.
There are 2 types of Series PC valves. Series PCM valves can be adjusted for required flows after being installed. Series PCK valves are factory-set for a specified flow and are not adjustable by the user.
