Sealing Performance Testing: Evaluates the valve's ability to prevent media leakage when closed.
Flow Characteristic Curve Testing: Determines the functional relationship between flow rate and valve stroke (opening degree) at different opening degrees.
Operating Pressure Difference Range Testing: Determines the pressure difference range between the inlet and outlet for which the valve can normally and stably regulate flow.
Actuator Performance Testing: For electric or temperature-controlled actuators, tests parameters such as output torque, stroke time, positioning accuracy, and repeatability error.
Pressure Resistance Testing: Verifies the structural integrity of the valve body and internal pressure-bearing components under short-term overpressure, ensuring no permanent deformation or rupture and guaranteeing system operational safety.
Service Life (Durability) Testing: Simulates actual operating conditions by subjecting the valve to repeated open-close cycles or regulation cycles, typically under specified pressure differences and temperatures.
Temperature-Pressure Cycle Testing: Places the valve in an alternating temperature and pressure environment, simulating system start-up and shutdown or changes in operating conditions, to verify the thermal fatigue performance and long-term stability of various valve components.
