KSDEU1PA-HN02
Name: Switching Directional Valve (Rexroth - BOSCH). - Directional Poppet Valve Solenoid Operated. - Type KSDE. - R : Maximum Operating Pressure 250 bar. - P : P-Spool. - 2 Main Connections. - Normally Open. Description: Based on the official Bosch Rexroth technical documentation, a direct-operated solenoid poppet valve (Type KSDE) with the specifications you described is identified by the type code KSDE R 1 P B / H N0 V .
This valve has two main connections, is normally open ("P" spool), and is rated for 350 bar (the "R" pressure variant). Key technical specifications are confirmed in the table below.

Mounting Cavity R/T-13A (Sun T-13A compatible)
🔧 Understanding the Type Code
Your specifications translate into the type code KSDE R 1 P B / H N0 V, which breaks down as follows :
KSDE: Directional seat valve, direct-operated, electrically actuated .
R: Maximum operating pressure 350 bar .
1: Component size 1 .
P: Symbol P, Normally open .
B: Component series B .
H: Mounting cavity R/T-13A .
N0: Without auxiliary (manual) actuation .
V: FKM seals .
The "R" pressure rating for the KSDE series has a standard maximum flow of 20 l/min, with a flow-optimized variant (R...-17) that can reach up to 60 l/min . The normally open state ("P") means flow is blocked when the solenoid is energized .
