Product Overview
The MAC 55B-14-PE-591JB and 56C-35-611JM are precision-engineered pneumatic solenoid valves manufactured by MAC Valves, a globally recognized leader in air valve technology. These direct-acting, balanced poppet solenoid valves are designed for high-cycle industrial pneumatic control, delivering fast response, consistent shifting, and long service life in demanding automation environments. The 55B series is a compact 4-way solenoid valve with a balanced poppet design, while the 56C series offers a larger flow capacity in a robust inline body configuration. Both models operate on the balanced poppet principle, ensuring reliable actuation regardless of pressure fluctuations and providing excellent repeatability for directional control of pneumatic actuators, cylinders, and air-operated process equipment.
