The FD16PA2X/B03V12 check valve belongs to the FD Check Valves series produced by Bosch Rexroth and is used to control directional flow in hydraulic automation. It is built to a nominal size of 16 and mounts on sub-plates that follow porting pattern ISO 5781-06-07-0-00. Port a and port b each have a 16 mm passage, allowing a maximum flow of 200 l/min, while forward flow begins once the inlet reaches a cracking pressure of 2 bar. Pilot stabilization is handled by a 0.3 mm orifice, and remote actuation is available through a control port threaded G1/4.
The unit endures operating pressures up to 350 bar at ports a and x and up to 420 bar at port b, with the same 350 bar limit applying to the control pressure at port x. FKM sealing resists common hydraulic fluids and heat, and no secondary pressure relief valve is included. Installation requires four M10 × 100 screws to DIN 912-10.9 tightened to 75 Nm, and the assembly weighs 9 kg, factors that must be considered when selecting manifold thickness and handling equipment.
