  • TypeDrain Components
  • 4-way/3-position design enables versatile pneumatic circuit control
  • 24 V DC solenoid actuation provides reliable electrical operation
  • 30–145 psi pressure range suits a wide variety of compressed-air systems
  • NEMA 4 rating protects against water and dust ingress
  • 4 cfm flow capacity delivers sufficient air volume for typical applications

Industrial pneumatic control

The Parker B561BB549C is a 4-way 3-position solenoid air control valve designed for automated pneumatic systems. It operates on 24V DC supply and features a centre-open configuration that exhausts both output ports when de-energised. The body-ported inline design suits direct mounting in compressed-air circuits.

Upgrade from manual or 3-way valves

This valve replaces hand-operated levers or simpler 3-way valves when bidirectional actuator control with a neutral position is required. The jump is justified when a machine cycle needs hold or float states between extend and retract strokes. It delivers 1.4 cfm flow at a 1.1 Cv coefficient across 30 to 145 psi operating pressure.

Integration requirements

The valve accepts 1/4 inch NPT ports for supply, exhaust and pilot connections. A 15 mm 3-pin male DIN connector provides the electrical interface. NEMA 4 rating protects the solenoid against splashing water and dust. Pilot pressure of 30 psi minimum must be available for reliable shifting. Vacuum service up to 28 in Hg is supported.

Questions about this item

What thread size do I need for the 1/4 in ports on this B561BB549C valve?

The valve uses 1/4 in NPT threads on both the main and pilot ports, so matching NPT fittings are required.

How do I wire the 24V DC solenoid on this 561 series valve?

Connect the 24V DC supply to the 3-pin male DIN connector; the valve draws power through this plug and requires 30 psi pilot pressure to shift.

When should I plan to replace the internal seals on this Parker solenoid valve?

Inspect seals if leakage appears or flow drops below the rated 1.4 cfm; operating within 30–145 psi and 0–28 in Hg vacuum range maximises seal life.
