Product Overview
The HYDAC SAF20M12N210A-S13 (Part No. 2120046) is a precision-engineered accumulator safety block designed to provide safe, reliable isolation and pressure protection for hydraulic bladder, diaphragm, and piston accumulators. As a dedicated pressure control valve assembly, it combines manual shut-off, pressure relief, and unloading functions within a single compact manifold body. The SAF series safety block is a critical safety component in industrial hydraulic systems, ensuring that accumulators can be safely depressurized for maintenance while protecting the circuit against inadmissible pressure spikes. Manufactured by HYDAC, a global leader in fluid power technology, this block is rated for a nominal pressure of 210 bar and features a 12 mm nominal bore size, making it suitable for a wide range of medium-to-high pressure industrial applications.
