Product Description
AD-SL231D Series Double Solenoid Valves for Pneumatic Punch Safety
Product Overview: The AD-SL231D Series is a high-safety double solenoid valve specifically engineered for controlling clutches and brakes on pneumatic punch presses. Acting as the heart of the press safety system, this series utilizes a redundant dual-structure. This ensures that in the event of a single solenoid failure or spool sticking, the system immediately cuts off the air supply and exhausts pressure, preventing accidental continuous stroking. These valves are fully compliant with press safety standards and are vital for operator protection.
This category highlights essential high-performance configurations: the standard AD-SL231D-304D and 406D, alongside the advanced DD2 monitor-equipped versions. Powered by 24V DC, these valves are the premier choice for precision punching machines, metal forging equipment, and pneumatic safety control circuits.
Key Technical Advantages:
Dual Redundant Safety Architecture: Features two independent pilot control units that monitor each other, eliminating the risk of unintended operation due to a single-point failure.
Ultra-Fast Exhaust Performance: Optimized exhaust flow paths designed for emergency braking, ensuring clutch pressure is released within milliseconds for instantaneous stopping.
Integrated Monitor (DD2 Option): Available with a checking monitor to detect synchronization between the two valves in real-time. If desynchronization occurs, the system locks to prevent accidents.
Durability & Shock Resistance: Specifically reinforced for the high-vibration environment of punch presses, with wet-pin solenoid coils offering an exceptionally long service life.
