The Wandfluh SDSPM22-BA is a high-performance, direct-operated proportional spool valve designed as a slip-in cartridge with an M22x1.5 thread. This 2-way valve precisely controls the volume flow in hydraulic systems, adjusting it in proportion to the electrical input signal. Its robust construction with hardened and ground valve components ensures minimal wear and a long operational life, making it ideal for demanding industrial applications requiring accurate flow regulation. The valve’s cartridge design allows for compact and easy integration into manifold blocks.
