6-Spool Hydraulic Valve Guide: 11 GPM, 3600 PSI & BSPP Explained
A hydraulic control valve is only compatible when its flow, pressure rating, port standard, spool count and cylinder type all match the system. This VEVOR valve is a 6-spool directional control valve rated for up to 11 GPM and 3600 PSI, with 1/2-inch BSPP ports, spring-return spools and double-acting cylinder applications.
What do 6 spool, 11 GPM, 3600 PSI and BSPP mean?
6 spool means the valve bank has six manually controlled spool sections. 11 GPM is the listed maximum flow rating, while 3600 PSI is the listed maximum pressure rating—not a target pressure setting. 1/2-inch BSPP identifies the port thread standard. The product is listed for double-acting cylinders, with spring-return spools that return toward neutral when the control is released.

What Does “6 Spool” Mean?
A spool is one control section inside the valve bank. A 6-spool valve therefore provides six separate manual control sections. In a compatible hydraulic system, each spool can be assigned to a function such as extending or retracting a double-acting cylinder.
More spools do not automatically mean more hydraulic power. Spool count tells you how many functions can be controlled from the valve bank; pump flow, system pressure and actuator size determine the hydraulic performance available to those functions.
What Does the 11 GPM Flow Rating Mean?
The product lists a maximum flow of 11 gallons per minute. Flow rating is a compatibility limit for the valve; it is not a promise that every hydraulic system will operate at exactly 11 GPM. The actual system flow comes from the pump and operating conditions.
What Does 3600 PSI Mean?
The listed 3600 PSI figure is the valve’s maximum pressure rating. It should be treated as an upper component rating, not as a recommended pressure setting.
A hydraulic system must stay within the lowest applicable rating among the pump, hoses, fittings, valve, cylinders and other components. The correct operating and relief settings depend on the machine design and should follow the equipment manufacturer’s specifications.
Why the 1/2-Inch BSPP Port Standard Matters
BSPP identifies a British Standard Pipe Parallel thread form. A 1/2-inch BSPP port is not interchangeable with every 1/2-inch hydraulic fitting that may look similar. Thread standard, sealing method and fitting geometry must match the port specification.
Before purchase, confirm that the hoses or adapters in the hydraulic system are compatible with 1/2-inch BSPP ports rather than NPT, BSPT or another standard.
Compatibility Checklist Before Choosing This Valve
01 · Confirm flow
The system’s maximum expected flow should stay within the valve’s listed 11 GPM rating.
02 · Confirm pressure
System pressure must remain within all component ratings. Do not treat 3600 PSI as a universal operating target.
03 · Confirm port standard
Verify 1/2-inch BSPP compatibility for the required inlet, outlet and work-port connections.
04 · Confirm actuator type
This product is listed for controlling double-acting cylinders.
05 · Confirm six functions are appropriate
Choose a six-spool bank only when the machine actually needs that number of independently controlled hydraulic functions.
Hydraulic Safety Notes
- Hydraulic fluid under pressure can cause severe injection injuries. Never check for leaks with bare hands.
- Depressurize and isolate the system before inspection, service or component replacement.
- Do not exceed the pressure, flow, temperature or fitting ratings of any connected component.
- Do not adjust relief pressure without the machine manufacturer’s specifications and appropriate hydraulic test equipment.
- Use qualified hydraulic service personnel when the system design or compatibility is uncertain.
Quick Buying Checklist
- I need six independently controlled hydraulic functions.
- My expected flow is compatible with the 11 GPM valve rating.
- My system pressure stays within the complete system’s component ratings.
- My fittings or adapters match 1/2-inch BSPP ports.
- I am controlling compatible double-acting cylinders.
- I have verified the machine’s hydraulic circuit requirements before ordering.
