ZGQ - Parsing W electromagnetic valve: ZGQ - W solenoid valve used in zero pressure and pressure pipe for a energy-saving solenoid valve, according to different divided into usability zero pressure start and bring pressure start, after double coil control. A coil control start, B coil control closed, when A coil electricity pole move up into the card slot by the steel ball to pin it to death. When energized coil steel ball around B activities, rod moves down, the deputy valve closed, so that the main valve on the inferior vena difference of pressure makes the valve closed, so as to achieve the effect of energy saving ZGQ - W solenoid valve at the same time can also be equipped with signal feedback device according to the requirement, also can be equipped with explosion-proof device. This product can be divided into single zero pressure since the type and function can be used for compressed air, steam, water, oil, etc. ZGQ - W electromagnetic valve internal structure, internal structure by looping, piston and rod strength activity. By the loop is divided into upper and lower cavity by extension rod is divided into two parts inside and outside. 1. Internal use a metal seal can be used in high temperature and high pressure rod can is made of four fluorine soft seal, rubber can be used for natural gas, coal gas, compressed air. Due to adopt double deck structure, the distance between coil and the heat source also far different from and ZCG solenoid Industrial Valves tube radiator, greatly reduced the heat damage to the coil to reduce the risk of the coil burned. ZGQ - W monomer type applies only to zero pressure pipeline, choose according to actual demand the product, can be used to design a single zero pressure system, the price is relatively cheap. About ZGQ - Troubleshooting W electromagnetic valve: valve cannot open: possible coil burned ( Caused by long-term electricity work) To see if there are any more damage to the pipe valve ring whether medium containing solid particles check B coil structure is normal work steel ball if there is activity to check whether there is deformation of the valve stem not closed: check whether live A coil power check piston rod seal is damaged or activities for wear check B steel ball is working correctly, if not add lubricating oil or returned to the factory maintenance
