MAC VALVES solenoid valve quotation

MAC VALVES solenoid valve quotation：The MAC 200 series is a three-way lift valve with direct electromagnetic operation. This series can also be used for hazardous location applications (Class I/Div B, C and D - Class II/Div E, F and G). It also has a short stroke solenoid valve, a balance lift valve, and a reset spring for *. These features translate into high shifting force, fast response time, and long lifespan.First level distributorMAC VALVES solenoid valve 250B-111CAAA.

Working principle of three-way solenoid valve: one in, two out: (ZC2/31) When the solenoid valve coil is energized, the first channel of the outlet medium end (2) is opened and the second channel (3) is closed;

MAC VALVES solenoid valve quotation：

The frequency of malfunctions of solenoid valves in production sites is not high, and the main faults are often caused by poor quality of the control medium or control gas source of the solenoid valve. Generally, the following situations inside the solenoid valve are the reasons that hinder its normal operation and shorten its service life:

(1) Changes in the medium during use;

(2) Rust inside the takeover;

(3) The oil oxidation of the air compressor produces impurities such as carbon particles and tar, which mix into the pipeline, or there are impurities such as dust particles and dirt in the pipeline, causing blockage of the solenoid valve pilot valve pneumatic control or jamming of the valve core;

(4) The solenoid valve coil has been charged for a long time and burned out.

Therefore, regular maintenance 1-2 times a year is a reliable and long-lasting method for solenoid valves. Take advantage of equipment downtime to perform the following inspection and maintenance work on solenoid valves:

(1) The solenoid valve coil component should not be disassembled. The main inspection method for the coil is to measure the coil resistance value and establish an original ledger. Coils with significantly different coil resistance values from the same type of solenoid valve standard should be replaced to avoid misoperation;

(2) For the solenoid valves of the ash removal system and turbine oil system, due to operating environment or oil quality issues, the valve core is prone to jamming. Regular disassembly of the solenoid valve as a whole should be carried out and cleaned with solutions such as kerosene and trichloroethylene. However, attention should be paid to the possibility of rubber parts swelling, so they should be replaced.

First level distributorMAC VALVES solenoid valve 250B-111CAAAInstallation precautions:

1. During installation, attention should be paid to aligning the arrow on the valve body with the flow direction of the medium. It cannot be installed in places with direct dripping or splashing water. The solenoid valve should be installed vertically upwards;

2. The solenoid valve should ensure normal operation within a fluctuation range of 15% -10% of the rated voltage of the power supply;

3. After the installation of the solenoid valve, there should be no reverse pressure difference in the pipeline. And it needs to be powered on several times to reach the appropriate temperature before it can be officially put into use;

4. Before installing the solenoid valve, the pipeline should be cleaned. The incoming medium should be free of impurities. Install a filter in front of the valve;

5. When the solenoid valve malfunctions or is cleaned, a bypass device should be installed to ensure the continued operation of the system.
