Product Overview
The Rexroth M-3SMM6C33/420 (Material Number R900054483) is a direct-operated manual directional seat valve engineered for precise control of hydraulic fluid flow direction in industrial systems. Part of the Rexroth M-3SMM series, this valve utilizes a seated poppet design that ensures zero-leakage sealing in the closed position, making it ideal for applications requiring positive shut-off and reliable load holding. The valve is actuated via a manual lever, providing tactile operator control without the need for electrical or pilot signal interfaces. With a nominal size of NG6 (CETOP 3 / ISO 4401-03), it is designed for compact manifold mounting and delivers dependable performance in demanding hydraulic circuits.
