The Bosch Rexroth SL6PB1-6X (R900491117) is a high-performance, hydraulically actuated industrial hydraulic valve designed for reliable blocking of oil flow at selected ports. This seat valve is pilot-operated with a spool symbol for ports A and B and can handle a maximum pressure up to the specified limit. It features an electrical connection with a connector pole and M x coding A according to EN standards. With its subplate mounting configuration, the SL6PB1-6X conforms to CETOP D and ISO connection diagrams, ensuring compatibility with standardized systems. The valve offers six ports and one switching position, while its construction includes NBR seals suitable for various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. The SL6PB1-6X valve operates by allowing flow from direction A to B without external pilot pressure when the condition pA > pB (cracking pressure of the compression spring) is met. For reverse flow, the valve closes hydraulically tight until sufficient pilot pressure at port X moves the control spool to open the seat poppet. This model provides options for different types of operation: with a large spool face connected to pA or versions with or without preopening. The preopening feature ensures secure unloading even at low pilot pressures and reduces switching shocks by dampening decompression. Without preopening, valves may experience sudden unloading which could lead to premature wear or noise. Additionally, this model can be modified from type SV to SL by exchanging plugs; one plug must always be installed. It is designed for subplate mounting with porting patterns according to ISO standards for leakage-free blocking of an actuator port. Options include various cracking pressures and corrosion-resistant designs. In summary, the Bosch Rexroth SL6PB1-6X (R900491117) offers robust performance for hydraulic applications requiring precise control over fluid flow in a durable and adaptable package.
