Directional Spool Valve Z4WH16X163-5X - Bosch Rexroth R901221055

A shut-off function can be housed in the stack without an extra valve on the manifold. The directional spool valve Z4WH16X163-5X is built as a sandwich plate and goes between subplate and main valve. It is hydraulically actuated, carries up to 300 l/min and holds 315 bar operating pressure.

Benefits

• Sandwich plate design, so no additional space on the manifold is needed.
• Flow up to 300 l/min in size 16.
• Operating pressure to 315 bar, NBR seals, HL hydraulic fluid.
• Hydraulic actuation with two switching positions, without manual override.
• Spool symbol X163, connection diagram ISO 4401-07-07-0-05, four ports.

Applications

Sandwich plates of this kind sit under directional valves in machine tools and presses when a cylinder has to be held against its load. Because the element lies inside the stack, piping and manifold footprint stay unchanged. Actuation comes from pilot pressure rather than from a solenoid.
