Which Hydraulic Valves are your products compatible with?

If there is a valve on the market, chances are P-Q Controls is able to control it. The following is a list of the more common valve manufacturer's that we have configured our controls for;

Do I need a PQ Valve Drive Board as well?

If your valve does not have integrated electronics (i.e., on-board valve driver), then a PQ Valve Drive Board is likely required. For more information on our line of drivers, please click here.



What are the benefits/disadvantages of a valve with integrated electronics?

The benefit of valves with on-board electronics is that the drivers are already integrated with the valve, which eliminates the need to externally mount the driver. The disadvantage is that the electronic driver is specific to that valve, and cannot be used to drive other valves.
A P-Q Valve Drive Board, however, can be adjusted (in-field) to drive virtually any valve on the market. Thus, a customer can easily swap to a different valve (or replace a defective one) without having to buy new electronics to drive the new valve. It is also worth noting that on-board electronics limits the customer in his options for a command source (since not all joystick companies produce joysticks that meet the input requirements of certain on-board drivers). Using a P-Q Valve Drive Board guarantees a compatible marriage to our controls.



I'm new to electro-hydraulics. What else do I need to know to set up a system?

As a general rule, each proportional valve is a single axis of control (e.g., Forward/Reverse is one axis, Left/Right is one axis, and Boom Up/Down is one axis), which in turn requires its own driver and single axis joystick/control. A multi axis joystick may be used to control multiple valves with one hand.



The following is an illustration of what a typical setup would look like; (1) P-Q Valve Drive Board, (1) Single-Axis Joystick, and (1) Valve.

PWM A/B - Pulse Width Modulation signal output for the A-direction and B-direction (normally the A-direction is positive/forward, and the B-direction is negative/reverse)
AUX A/B - Auxiliary output for the A-direction and B-direction (these are digital on/off switches used to control miscellaneous functions)
COM - Common Auxiliary Output (equivalent to jumpering Aux A&B)
PT+,PT-,SIG - These connect to your command source, which in this case is a standard M115 Hall Effect Joystick. PT+ powers the joystick, which in turn sends a variable signal back to the board.
