Product Description

The PARKER 443779W (7321BAN00) solenoid valve is a 2/2-way normally closed pilot operated brass solenoid valve designed for reliable control of air, water, neutral gases, hydraulic fluids, petroleum products, and other compatible industrial media. When supplied with the PARKER 495905C2 (HZ96C2) explosion-proof coil, the valve becomes suitable for hazardous area applications requiring ATEX-certified electrical protection.

The valve features a forged brass body, stainless steel internal components, and an NBR diaphragm, providing excellent durability and long service life in demanding industrial environments. The pilot-operated design enables efficient operation with low power consumption while maintaining reliable flow control.

The supplied 495905C2 ATEX coil operates on 24VDC, 8W and is certified II 2G EEx dm IIC T4, making it suitable for installation in potentially explosive gas environments. The coil is encapsulated in synthetic material with IP67 protection, ensuring reliable performance under harsh industrial conditions.

This assembly is commonly used in oil & gas, petrochemical plants, chemical processing facilities, palm oil mills, fuel handling systems, and industrial process automation where explosion-proof solenoid valve operation is required.
