Install this #10 MB plug to

run open center. Valve will

allow all oil to pass through

it, then divert necessary oil

to the hydraulic motor.

Install this cavity plug to run

closed center. Valve will allow

all oil motor needs to pass

through.

Tractor Hydraulic Requirements

The hydraulic drive motors require a maximum of 7 gallon per minute of hydraulic oil at a maximum

pressure of 1500 psi. Average oil requirement is usually less then 5 gallon per minute.

With minor modification the drive PWM valve will function with a tractor equipped with a closed or open

center hydraulic system. Contact your tractor dealer to determine which hydraulic system your tractor

may have. Most recently manufactured tractors are equipped with a closed center hydraulic system.

The PWM valve is shipped with the closed center cavity plug installed.

Tractors with open center system:

1. When running in series with another

hydraulic motor, such as a planter fan motor.

The SureFire valve must allow all oil going

through the fan to pass through it. The

SureFire valve will be ‘open center’ and

divert the necessary oil to the SureFire

hydraulic motor.

2. When running in series with two SureFire

valve/motor combinations. This might

happen in the case of two seed drives or two

pumps. Each valve needs to let excess oil

pass through so the second valve has plenty

of oil to accomplish its necessary task.

Tractors with closed center system:

1. When running this valve by itself from a

tractor hydraulic remote. By running closed

center, the SureFire valve will use the

minimum amount of oil and cause the least

oil circulation and heating. This leaves the

most oil for other hydraulic functions.

2. When running off power beyond hydraulic

ports, the valve must be closed.
