Bosch Rexroth Z2SRK 10-1-10 RBLT Servo Valve

Bosch Rexroth Z2SRK 10-1-10 RBLT is a size-10 sandwich-plate, pilot-operated check valve in the Z2SRK family, designed for leak-free closure of two actuator ports in servo-hydraulic systems. It supports a maximum operating pressure of 210 bar (3100 psi) and a maximum flow of 80 L/min (21.1 GPM), making it suitable for precise backflow control within compact valve assemblies. The size-10 configuration is cataloged as RE21549 and follows standard porting patterns ISO 4401-3, NFPA T3.5.1M R1, and ANSI B93.7 D 03 to ensure compatibility with common sandwich-plate manifolds. This variant, denoted by RBLT, is commonly employed in servo-valve circuits where controlled port closure and protection of actuators are required, helping to maintain stability and responsiveness in hydraulic servo applications. The Z2SRK family is known for reliable, leak-free operation in high-precision hydraulic systems, making this valve suitable for integration into industrial automation equipment, CNC machinery, and robotics where backflow prevention and port isolation are critical.
