New rexroth hydraulic check valve R900483371 SL10PA1-42
These valves are used for the isolation of operating circuits which are under pressure, i.e. as a safe guard against the lowering of a load when a line break occurs or against creeping movements of hydraulically locked actuators.
The valve basically comprises of the housing (1), the poppet (2), a compression spring (3), the control spool (4) as well as an optional decompression feature as a ball poppet valve (5).
Types SV..A.. and SL..A.. (with decompression)
This valve is fitted with an additional decompression feature. When pressure is applied to port X, the control spool (4) is moved to the right. This firstly lifts the ball (5.1) and then the poppet (2) off their seats. The valve now permits flow from B to A.
Because of the decompression feature there is a dampened decompression of the pressurized fluid. Due to this possible pressure shocks are avoided.
The function of this valve corresponds to that of the type SV.
The difference is the external Y connection. Here, the annular area of the control spool (4) is separated from the port A. Pressure present in port A only acts on area A4 (9) of the control spool (4).
Type SV..PA.-4X/... (without pilot oil drain, with decompression)
Type SL..PB.-4X/... (with pilot oil drain, without decompression)
Great deal with this price !!!! You will not find a better price on these valves anywhere !!!
