Because of the dual-orifice design, there is a preset controlled pressure differential for the secondary steam system, while maximum pressure differential is available to discharge the condensate.
When design temperature or MDMT cannot coincide with the maximumpressure, the corresponding design pressure shall be designated together with the temperature.
当设计温度或最小设计金属温度与最大压力不符，应根据温度指定相应的设计压力。

Based on solenoid valve design theory, by estimating the maximum air pressure and spring force, a direct operated solenoid valve is designed to control the open and close of the air chamber.
