Rexroth LC50A05E7X/ R900938022
The Rexroth LC50A05E7X/ (R900938022) is a pilot-operated check valve, designed as a logic element in a cartridge style. This valve is engineered to provide leak-free blocking of hydraulic flow in one direction, while allowing free flow in the opposite direction. Upon application of sufficient pilot pressure at port X, the valve opens, permitting flow from port B to port A even when pressure at port A is higher than at port B (within the limits of the pilot ratio). Its cartridge design facilitates compact and straightforward installation into standardized cavities, making it suitable for various industrial hydraulic systems requiring reliable directional control and load holding.
