The Bosch Rexroth SV6PB1-6X (R900494086) is an advanced hydraulic isolator valve designed for subplate mounting, ensuring a leakage-free blockage of one actuator port even during extended periods of inactivity. It features a robust construction that includes a housing, seat poppet, compression spring, and control spool, with an optional preopening as a ball seat valve. This valve allows for unidirectional flow from A to B without external pilot pressure, relying on the cracking pressure of the compression spring to operate. In applications where bi-directional flow is necessary, the SV6PB1-6X can be activated by applying sufficient pilot pressure at port X. This moves the control spool and disengages the seat poppet from its seat. The design considerations of the valve ensure that it opens actively based on the pressure ratios on either side of the control spool and area ratios at the seat poppet. Bosch Rexroth offers two versions of this valve: Version A with preopening and Version B without preopening. Version A provides secure unloading even at low pilot pressures due to its twostage setup and increased control open ratio, while also dampening decompression to avoid switching shocks. Conversely, Version B may result in sudden pressure volume release which could lead to premature wear and noise. The SV6PB1-6X can be modified into type SL by exchanging plugs provided with it. It is designed for compatibility with porting patterns according to ISO standards and can handle various cracking pressures. Customers can choose between models with or without preopening based on their needs. Additionally, check valve installation sets are available separately for those who require them. This Bosch Rexroth valve is suitable for applications requiring maximum operating pressures up to bar levels and flow rates measured in liters per minute. Its versatility and optional corrosion-resistant design make it an essential component for hydraulic systems requiring precise flow control and reliable operation under challenging conditions.
