The Bosch Rexroth SL6PA3-6X (R901387396) is a high-quality isolator valve designed for subplate mounting, offering reliable performance for systems requiring leakage-free blocking of one actuator port, even during extended periods of inactivity. This valve is engineered to allow fluid flow from direction A to B without external pilot pressure, operating under the condition that the pressure at port A exceeds that at port B, which compresses a spring to crack open the valve. In the reverse direction, it ensures a hydraulically tight seal. The SL6PA3-6X features a robust construction comprising a housing, seat poppet, compression spring, and an optional preopening as a ball seat valve. Its control spool is activated by pilot pressure at port X, moving the spool and lifting the seat poppet to enable free flow in both directions when actively kept open. Bosch Rexroth provides two versions of this valve type: Version A with preopening and Version B without preopening. Version A benefits from a two-stage setup with increased control open ratio allowing for secure unloading even at low pilot pressures and dampened decompression to avoid switching shocks. On the other hand, Version B may experience sudden unloading of pressure volume leading to potential switching shocks which could cause wear on components and noise. This versatile SV type can be modified into an SL type by exchanging specific plugs; one plug must always be installed ensuring proper function. The valve adheres to ISO standards for subplate mounting and offers optional features such as various cracking pressures and corrosion-resistant designs. Individual check valve installation sets are available for customization according to system requirements.
