Technical Specifications

1. Voltage Options: The DMK – Z – 50 offers a variety of voltage options to suit different power supply requirements. It can be configured to operate on 24 VDC, 110V AC, 120V AC, 220V AC, or 230V AC (50/60 Hz). This flexibility makes it compatible with a wide range of industrial electrical systems. For example, in a factory with a predominantly 220V AC power supply, the valve can be easily integrated without the need for complex voltage conversion systems.
2. Connection Size: With a DN50 (G2”) inlet and outlet threaded port size, the valve is designed to handle a significant volume of compressed air. This size is suitable for applications where a relatively large – scale air flow is required, such as in large – capacity dust collectors or high – volume pneumatic conveying systems.
3. Working Pressure Range: It has a working pressure range of 0.1 to 0.8 MPa. This wide pressure range allows the valve to be used in diverse industrial scenarios. In low – pressure applications like some food and beverage production lines where gentle air pulses are needed, the valve can operate effectively at the lower end of the pressure range. On the other hand, in more demanding applications such as heavy – duty mining dust collection, it can handle the higher pressures without performance degradation.
4. Diaphragm Material: The diaphragm of the DMK – Z – 50 is typically made of NBR (Nitrile Butadiene Rubber). NBR is known for its excellent resistance to oil, fuel, and abrasion, which are common factors in industrial environments. This material choice ensures that the diaphragm can withstand the harsh conditions of continuous operation, resulting in a long – lasting and reliable valve.

Installation Guide

1. Pre – installation Checks: Before installing the DMK – Z – 50, it is essential to check the valve for any visible damage that may have occurred during transportation. Inspect the body, diaphragm, and electromagnetic coil for any signs of cracks, dents, or loose parts. Also, ensure that all the necessary installation accessories, such as gaskets and mounting brackets, are present.
2. Cleaning the Pipeline: The air supply pipeline should be thoroughly cleaned before installing the valve. Any debris, dirt, or moisture in the pipeline can cause damage to the valve’s internal components or affect its performance. Use compressed air or appropriate cleaning agents to remove any contaminants.
3. Mounting the Valve: The valve should be mounted in a location that allows for easy access for maintenance and inspection. Ensure that the valve is installed in the correct orientation, with the inlet and outlet ports properly aligned with the pipeline. Use the provided mounting brackets and fasteners to securely attach the valve to the support structure.
4. Electrical Connection: When connecting the electrical wires to the electromagnetic coil, follow the wiring diagram provided with the valve. Make sure that the electrical connections are secure and properly insulated. If the voltage is above 36V, it is recommended to ground the valve to ensure electrical safety.

Maintenance Tips

1. Regular Inspection: Periodically inspect the valve for any signs of wear or damage. Check the diaphragm for cracks, tears, or signs of excessive wear. Inspect the electromagnetic coil for any overheating or electrical issues. Look for any air leaks around the valve body or connections.
2. Cleaning: Clean the valve regularly to remove any accumulated dust, dirt, or debris. Use a soft brush or compressed air to clean the internal and external parts of the valve. This helps to maintain the valve’s performance and prevent clogging of the air passages.
3. Diaphragm Replacement: If the diaphragm shows signs of significant wear or damage, it should be replaced promptly. The replacement process is relatively straightforward, but it is important to use a genuine replacement diaphragm to ensure proper fit and performance.
4. Testing: Periodically test the valve’s operation to ensure that it is functioning correctly. Use a pulse control instrument to send electrical signals to the valve and check that it opens and closes properly. Monitor the air flow and pressure to ensure that they are within the specified range.

Comparison with Similar Products

1. Response Time: Compared to some other electromagnetic pulse valves in the market, the DMK – Z – 50 offers a faster response time. This means that it can open and close more quickly in response to an electrical signal, which is crucial for applications that require precise timing of air pulses. For example, in a high – speed dust collection system where rapid cleaning of filter bags is essential, the fast response time of the DMK – Z – 50 can result in more efficient dust removal.
2. Durability: Thanks to its high – quality materials and robust construction, the DMK – Z – 50 has a longer service life compared to some similar products. The use of NBR diaphragms and aluminum alloy bodies contributes to its durability, making it suitable for use in harsh industrial environments where other valves may fail prematurely.
3. Energy Efficiency: The DMK – Z – 50 is designed to be energy – efficient, consuming less power during operation. This is an advantage over some older – style or less – efficient pulse valves, as it helps to reduce the overall energy consumption of the system and lower operating costs.
