Introduction

Heldon packed capped line valves are used to isolate an individual line, component or part of refrigeration or air-conditioning system.  They are designed to streamline flow leading to an extremely low pressure drop across the valve. The bodies design incorporates large volume areas leading on to and off the seat to enable the refrigerant velocity to reduce while making the change in direction. This design feature minimises turbulence, reduces pressure drop and makes Heldon’s packed capped line valves ideal in modern, efficient refrigeration and air-conditioning systems.

The bodies are cast or forged brass depending on the model and have a unique spindle/valve seat mechanism that is easily removed and fully serviceable. The stainless steel spindle is sealed with gland rubber and the  stem plate is made from a polyamide nylon ensuring a complete shut off with minimal pressure applied.

Suitable for all fluorinated refrigerants they are available in two designs, Straight or Right Angle, for applications that require high usage, high flow rate and to be fully serviceable. Service kits are available as a standard part for both versions.
