Sporlan FBS1-4C Expansion Valve W/ .5" X 3" Bulb 1/4" IN X3/8" OUT

The Sporlan FBS1-4C Expansion Valve with 0.5" x 3" bulb and 1/4" in x 3/8" out is a thermostatic expansion valve used in commercial appliance systems. It controls the appliance flow to the evaporator by sensing temperature at the evaporator outlet with its remote bulb to ensure correct superheat and consistent cooling operation. The valve is commonly used in appliance cabinets, prep tables, and walk-in cooler systems where the refrigerant is to be controlled accurately to operate efficiently. It is a component of the appliance circuit between the liquid line and evaporator, and it maintains the proper pressure and temperature balance within the system in continuous cooling cycles in foodservice and industrial refrigeration equipment.
