The Structural Concepts 20-13510 Thermostatic Expansion Valve regulate refrigerant flow to maintain consistent cooling in compatible SBZ refrigeration systems. It works by controlling the amount of refrigerant entering the evaporator in response to temperature and pressure conditions, supporting proper refrigerant distribution and heat absorption. This regulation helps maintain stable... https://partsfe.ca/structural-concepts-20-13510-thermostatic-expansion-valve-sbz/2-20-13510.html
