Product Description

Series TLEX 0.5 - 4.5 Thermostatic Expansion Valve with built-in orifice, solder connections, adjustable superheat setting and external pressure equalization.
Thermostatic expansion valve for multiple injection in plants with one or more circuits, particularly for series systems such as refrigerated cabinets, deep freeze chests, freezers, fermentation interrupters, ice and cream machines, compact systems in refrigeration and air conditioning. Imperative for multiple injection by liquid distributors or for use with plate head exchangers.
  • Warm control diaphragm provides best reliability
  • Extreme durability thanks to welded stainless steel head and stainless steel diaphragm
  • For maximum pressure PS see specification sheet
  • For maximum test pressure PF see specification sheet
  • Special versions (bypass, other refrigerants, etc.) on request
  • For capacities of orifices download attached engineering manual or check with our selection software Valve Tool
