  • Unobstructed flow path
  • Single moving part
  • High flow capacity
• Fully Supported & Balanced Diaphragm
  • Requires low opening and actuation pressure
  • Excellent low flow regulation performance
  • Progressively restrains valve closing
  • Prevents diaphragm distortion
• External Installation
  • Easy access to valve and float
  • Less wear and tear
  • Simple in-line inspection and service

TECHNICAL DATA

OPERATION

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.
