SD11 Series Monoblock Directional Valve
MODEL：SD11 Monoblock Directional Valve
APPLICATIONS & FEATURES：
SD11 Series Monoblock Valves are simple,compact and heavy duty designed mnoblock valve from 1 to 7 sections for open and closed center hydralic systems.
Fitted with a main pressure relife valve and a load check valve.
Circuit form: Parallel oil circuit design, each circuit is independent of each other but can work simultaneously, so that multiple working mechanisms can act simultaneously or individually, improving work efficiency and flexibility.
When in the middle position, the P→T port is directly connected to reduce no-load energy consumption
Optional power beyond port(only for parallel or tandem circuit) .
Diameter 20mm-0.79 in interchangeable spools.
A wide variety of service port valve options.
Actuation is manual,pneumatic,electro-pneumatic,hadralic,elector-hydralic,with solenoid and remote with flexible cables spool control kits.
