The Bosch Rexroth SV6PA2-6X (R901407741) is a sophisticated isolator valve designed for subplate mounting and tailored to facilitate the leakage-free blocking of one actuator port, even during extended periods of inactivity. This check valve is engineered with a robust housing, a seat poppet, compression spring, and control spool, with the option of including a preopening as a ball seat valve. It allows for unidirectional flow from A to B without external pilot pressure when pA exceeds pB above the cracking pressure of the compression spring. The SV6PA2-6X operates by utilizing pilot pressure at port X to shift the control spool towards the seat valve, lifting the seat poppet and enabling bidirectional flow while actively keeping the valve open. The pressure ratios on both sides of the control spool and area ratios at the seat poppet are critical for ensuring that the valve opens actively. There are two versions available: Version A with preopening and Version B without preopening. Version A offers a two-stage setup with an increased control open ratio that allows secure unloading even under low pilot pressures while minimizing switching shocks through dampened decompression. Conversely, Version B may cause sudden unloading of included pressure volumes, potentially leading to premature wear on components due to switching shocks. Furthermore, it's possible to convert type SV into type SL by exchanging plugs; one plug must always be installed for proper function. The SV6PA2-6X adheres to ISO standards for porting patterns and is capable of handling maximum operating pressures up to bar and maximum flow rates up to l/min. Options include various cracking pressures and corrosion-resistant designs. Additionally, individual installation sets for check valves are available separately. This versatile component ensures reliable operation in systems requiring precise hydraulic control and isolation capabilities.
