Hydraulic control valves start and stop fluid flow into hydraulic cylinders or hydraulic motors. They operate either manually or electronically (solenoid-operated). The number of cylinders or motors that a control valve can operate depends on the number of spools. The flow rates represent the maximum allowed GPM (Gallons Per Minute) that a valve can handle. A common example of a hydraulic control valve is the loader valve on a tractor.

Hydraulic control valves start and stop fluid flow into hydraulic cylinders or hydraulic motors.
These Hydraulic Control Valves operate any hydraulic cylinders (&#;A&#; Spool) or hydraulic motors (&#;D&#; spool) using electronic switch boxes. These valves have Max. allowed flows of either 15 GPM or 25 GPM. In addition, they have (1) inlet port and (1) high-pressure tank port.
These Hydraulic Control Valves operate any hydraulic cylinders (&#;A&#; Spool) or hydraulic motors (&#;D&#; spool) using electronic switch boxes. These valves have Max. allowed flows of either 13 GPM, 21 GPM or 27 GPM. In addition, they have (1) inlet port and (1) low-pressure tank port, (1) optional power-beyond port. These valves convert for use on closed-center hydraulic systems (adapter required).
These Hydraulic Control Valves operate any hydraulic cylinders (&#;A&#; Spool) or hydraulic motors (&#;D&#; spool) using levers or cables. These valves have Max. allowed flows of either 11 GPM, 21 GPM or 31 GPM. In addition, they have (1) inlet port and (1) low-pressure tank port, (1) optional power-beyond port. These valves convert for use on closed-center hydraulic systems (adapter required).
Typically, there are seven hoses or steel tubes connected to the loader valve. If only six hoses or tubes, there is no Power Beyond Port on your loader valve. The 1st four connect to your loader for the up, down, dump, and curl functions. The fifth line comes from your pump to feed your loader valve. The sixth line goes directly to your reservoir. When the pressure relief valve opens, fluid dumps directly to the reservoir. The seventh line connects to the &#;Power Beyond Port&#; on your loader valve to power valves beyond the loader valve.
On some loader valves, a &#;PB&#; stamped marking exists next to the power beyond port. Some loaders indicate their power beyond port with green tape or a green mark on the hose or valve. Some loader valves have a power beyond sleeve inserted in the power beyond port. This sleeve looks like a nut; however, it is 3 to 4 times longer than a normal sized nut. On some loader valves there are no clues to help determine which connection is the power beyond port. Your owner&#;s manual may not even indicate the location.
The power beyond conversion plug installs into the N port of ONLY MONOBLOCKS (NOT ON OUR D03 STYLE VALVES) to add another valve downstream. For example, if you were to attach two Monoblock valves in-line together, you would need the power beyond conversion plug. If you are connecting this valve to your power beyond on your loader valve, you DO NOT need the power beyond conversion plug.
The control valve comes with a G thread (British Pipe Thread Parallel) style to fit the N port of the Monoblock valve. Please refer to the product listing to ensure you are purchasing the correct power beyond adapter, as we also carry the adapter in SAE thread. We carry the P40G-PB, P80G-PB, and P120-PB adapter plugs.

The power beyond conversion plug installs into the N port of Monoblocks to add another valve downstream.
The closed center conversion plug installs into the N port of ONLY MONOBLOCKS (NOT ON OUR D03 STYLE VALVES) to convert the open-center valve into a closed-center one. If your system is a closed center system, you need this plug. If you are unsure if your tractor is open-center or closed-center, please refer to your owner&#;s manual or Google machine specs.
The control valve comes with a G thread (British Pipe Thread Parallel) style to fit the N port of the Monoblock valve. Please refer to the product listing to ensure you are purchasing the correct power beyond adapter, as we also carry the adapter with SAE thread. We carry the P40G-CC, P80G-CC, P120-CC adapter plugs.

Each port features a lettered marking to indicate what it is.
Detents install into a valve. They allow you to either lock a handle into a &#;work&#; position (allowing fluid to flow to a work port hands free), or cause a handle to spring back into the neutral position when released.
We offer P40 valve detents that lock in all positions, lock in rear position, lock in forward position and a float detent. The float detent must be purchased with a float spool.
We also offer P80 valve detents that lock in all positions, lock in rear position, and lock in forward position.
Spools are cylindrical components machined to slide in a close-fitting bore of a directional control valve. We carry 3 different types that operate very differently:
A Spool (Controls Double Acting Cylinders).
D Spool (Controls Hydraulic Motors)
K Spools (Float Spool)
Spools are cylindrical components machined to slide in a close-fitting bore of a directional control valve.
