The Needle Valve  allows continuous flow from Valve inlet into the Control Chamber . When water level rises, it pushes the Float  up throttling the Float Pilot . Pressure in the control chamber accumulates, causing the Valve to throttle closed, reducing filling rate, and eventually closing drip tight. Should level fall, the float pilot releases pressure from the control chamber causing the Valve to modulate open. The needle valve controls Valve closing speed. The Cock Valve  enables manual closing.
