The EPH TA230 is a 230V 4-wire thermal actuator designed for precise valve control in heating and HVAC installations. Engineered for normally closed (NC) operation, this unit requires electrical power to open, providing a fail-safe mechanism for automated climate control systems. It is constructed to function effectively in ambient temperatures ranging from 0-50°C and features a robust spring pressure of 125N to ensure consistent valve performance over extended periods. The inclusion of an integrated auxiliary connection offers increased flexibility for complex system configurations and integration with existing building management setups.
