The Bosch Rexroth SV6PB1-6X/V (R900593008) is an advanced isolator valve designed for subplate mounting, providing a reliable solution for the leakage-free blocking of one actuator port, even during extended periods of inactivity. This valve is characterized by its robust construction which includes a housing, seat poppet, compression spring, and control spool. An optional preopening feature as a ball seat valve is also available. The SV6PB1-6X/V valve operates by allowing flow from direction A to B without external pilot pressure when the pressure at port A exceeds that at port B. For reverse flow, the valve closes hydraulically tight until pilot pressure at port X displaces the control spool and lifts the seat poppet from its seat to enable free flow in both directions. The active opening of this valve depends on pressure ratios and area ratios between the control spool and seat poppet. Bosch Rexroth provides two versions of this isolator valve: Version A with preopening allows for secure unloading even at low pilot pressures and mitigates switching shocks with a dampened decompression feature. Conversely, Version B without preopening may result in sudden unloading of pressure volume, potentially causing premature wear and noise. This versatile valve can be converted from type SV to type SL by exchanging plugs provided in its design. It adheres to ISO standards for porting patterns and offers various cracking pressures based on user requirements. Additionally, it comes with an option for internal pilot oil return and can be ordered with or without preopening based on application needs. Check valve installation sets are available individually, and there is an optional corrosion-resistant design for more demanding environments. The Bosch Rexroth SV6PB1-6X/V isolator valve is suitable for applications requiring maximum operating pressures up to bar levels and can handle maximum flow rates measured in liters per minute (l/min), making it a versatile component in hydraulic systems requiring precise control over fluid direction and flow.
