Bermad - Model PC-70-X-M - 3W Paddle Flow Control Pilot

This 3-way pilot provides the valve a flow control feature combined with fully open mode, as long as demand is below setting. It is a direct-acting pilot, actuated by a paddle that is positioned within the flow stream. Should demand rise above the setting, the increasing flow dynamic force moves the paddle, which thereby pushes the pilot trim against the spring force. This introduces control water flow into the control chamber, causing the main valve to throttle closed, limiting system flow to the pilot setting. When demand is below setting, the spring force pushes the pilot trim against the decreasing flow dynamic force on the paddle, which thereby moves back to a vertical position. This vents the water from the control chamber, causing the main valve to fully open, minimizing valve head loss.
