Packless Line Valves
 
Introduction
  • Heldon packless line valves (Diaphragm Valves) are used to isolate an individual line, component or part of refrigeration or air-conditioning system. They are engineered to offer both long life and precise sealing making them the ideal choice as a long term positive isolation valve.
  • Heldon packless line valves feature a forged brass body with maximised post sizes for a greater flow and lower pressure drop.
  • Three stainless steel diaphragms separate the stem from the seat ensuring the valve’s longevity and preventing leakage during the life of the valve.
  • The valve seat is made from a polyamide nylon ensuring a complete shut off with minimal pressure applied.
