Selection Guide – Is This 3 Spool Monoblock Directional Valve Right for You?

Before ordering your 3 spool monoblock directional valve OEM units, consider the following questions to ensure proper selection:

Is your system flow rate within 11 GPM?

This 3 spool monoblock directional valve is rated for 11 GPM maximum flow. If your system requires higher flow capacity, consider our P80 Series (21 GPM) or P120 Series (31 GPM) monoblock valves. For tractor installations, check the “Hydraulics – Pump Flow” specification at tractor-data.com.

Do you have an open center or closed center hydraulic system?

This valve is configured for open center hydraulic systems (pump-to-tank flow) as standard. If you have a closed center system, you’ll need to purchase a closed center adapter plug separately.

Note: This valve does not have load-sensing capabilities.

Do you have other valves downstream from this valve?

If you have other downstream valves (such as rear remote valves, backhoe valves, or 3-point hitch valves), you’ll need a Power Beyond adapter sleeve to provide pressure and flow to those valves.

Note: This applies to open center systems only. Closed center systems use a tee from the pressure line to connect additional valves.

Are you operating hydraulic cylinders or hydraulic motors?

• For hydraulic cylinders → Select A Spool (double-acting cylinders)
• For hydraulic motors → Select D Spool (motor control)

Important: D spools cannot be used for cylinder operation, and A spools cannot be used for motor operation.

System Connection Guide

Installing your 3 spool monoblock directional valve is straightforward with proper planning. This valve features the following ports:

P Port (Pressure Inlet): Connect to hydraulic pump outlet
T Port (Tank Return): Connect to reservoir/tank
A & B Ports (Work Ports): Connect to hydraulic cylinder or motor
N Port (Power Beyond): Optional port for connecting downstream valves

Typical Connection Configurations:

Standalone Operation: P port to pump, T port to tank, A/B ports to actuator
Series Configuration: Use Power Beyond sleeve; N port of first valve connects to P port of next valve
Closed Center Setup: Install closed center plug for use with closed center systems

Installation Tip: Verify all line connections and check port seals before system startup. Professional hydraulic technician installation is recommended for optimal performance.
