4-Way Reversing Valve performance requirements
4-Way Reversing Valve performance requirements Editing
1, commutation performance
Under the specified operating conditions, the solenoid valve can be reliably reversed after power, can be reliably reset after power failure.
2, Pressure loss
Pressure loss of solenoid directional valves by flow through the solenoid directional valve valve
The flow loss and throttling loss resulting from the port.
3, Internal leak volume
The internal leakage of the solenoid valve refers to the amount of leakage from the high-pressure cavity to the low-pressure cavity at various working positions under the specified working conditions.
4, commutation and reset time
The time required for the solenoid to be energized to the end of the spool commutation is the time required to return from the electromagnetic shutdown to the spool to the initial position.
5, commutation frequency
Maximum number of commutation times allowed within a unit time
6, Service life The solenoid valve is used to damage the main components, can not carry out normal commutation and reset action, or the use of its main performance indicators significantly deteriorated than the specified indicators experienced commutation times.http://www.shunfengvalve.com/4-way-reversing-valve-performance-requirements/4-Way Reversing Valve used in reversible refrigeration systems
