Operation method of valve element of Italian Atos DHA-0631/M24DC solenoid valve
a. In the switching process, the special valve cores to reduce the liquid impact: derivative valve cores 1/1, 4/8 and 15/1. Their special structure can reduce liquid impact during switching. When the maximum flow is greater than 80% of the rated value, it is not recommended to use this type of valve element, because a large pressure drop will be generated in the valve at this time.
b. Response time and control switching time: direct acting solenoid valve. The response time of the solenoid valve can be controlled by a specific device (option L): cooperating with I1 or * I8 type valve element, the corresponding actuator can smoothly speed up/down. The L * device can effectively control the switching time of the solenoid valve, and can slow down the speed of the valve element without weakening the electromagnetic force.
C. It has many different functions. Under normal application conditions, it is recommended to have a small back pressure (2bar) on the "T" port of the solenoid valve. Service conditions (viscosity and temperature of oil), elastic modulus of hydraulic system and electrical plug used all affect the response time.
d. Response time and control switching time: pilot operated solenoid valve. The corresponding time of the pilot operated solenoid valve can be adjusted through options/H (outlet throttling) and/H9 (inlet throttling) The pressure reducing valve is superposed on the pilot valve to adjust the pilot pressure, which can meet the switching needs of long response time. The option is actually to install a superimposed throttle valve between the main valve and the pilot valve, and the model is HQ - */U
