SMC Corporation VG342-5DZ-04A Solenoid Valves

SMC VG342-5DZ-04A is a compact, three-port, pilot-operated poppet solenoid valve designed for precise on/off control of compressed air in tight spaces. The unit uses a 24 V DC internal pilot coil and 1/2 in Rc port threads, with the body constructed from aluminum alloy and NBR seals, and it weighs about 1 kg. It supports an operating pressure range from 0.2 to 0.9 MPa and can function in vacuum or under low-pressure conditions, making it versatile for automation layouts that require reliable response in demanding environments. Power consumption is low: 4.8 W in the standard version or 2 W in the energy-saving variant, helping reduce heat in continuous-duty applications. The valve is normally closed (N.C.) in its de-energized state and offers DIN-terminal electrical connections, aligning with common industrial control panels. The VG342 family is designed for easy integration into compact manifolds and supports conversion considerations within the series for internal vs external pilot configurations, though VG342-5DZ-04A is specified as an internal-pilot valve. No lubrication is required for operation, contributing to simple maintenance in automation systems. With its rugged aluminum/NBR construction and low power draw, this model suits sequencing, selector, or divider roles in pneumatic circuits where space is at a premium and reliability is critical.
