PVC Series Brand-independent proportional valve checkers

One family of portable test kits for proportional valves of every brand. Pick the model that matches your valve: Non-OBE for valves without on-board electronics, OBE for valves with them.

One kit family, every valve brand

Most valve testers only work with one manufacturer’s valves. The PVC series is brand-independent: it drives the valve’s solenoids directly, so the same kit checks proportional valves from any maker — as long as the valve is within the kit’s voltage and current limits.

Any brand One kit for the mixed fleet of valves in a real plant.
No hydraulic pressure Test the valve on its own — no power unit, no running machine.
Bench or field Portable, in a rugged carry case.

Explore the series and pick your model

The right PVC depends on what is built into your valve. Answer the questions and we’ll highlight your model.

1. Does the valve have electronics mounted on it?

Look for an electronics housing fixed to the valve body. That is OBE — On-Board Electronics.

Not sure? Send us the valve’s make and model number and we’ll tell you which PVC fits.

Valve, card, or PLC?

A machine is drifting, jerking, or not holding position. Three parts could be to blame, and without a way to drive the valve on its own, teams swap parts on guesswork or send the valve out for testing.

A PVC drives the valve directly. If the spool responds smoothly, the valve is fine and the fault is upstream. If it doesn’t, you’ve found it.

PLC signal Is the controller sending the right command?
Amplifier card Is the card turning that command into coil current?
Proportional valve The PVC tests this one on its own — no PLC, no card, no pressure.

How it works

Connect

Plug the valve into the kit with the connectors supplied for your model.

Select the input command

Set the same type of input command the valve gets on the machine — voltage or current.

Command and watch

Turn the knob and read the command and solenoid current on the touch screen while the spool moves.

Where teams use it

  • Troubleshooting Isolate a faulty valve on the machine.
  • Bench testing Check valves returned from service or repair.
  • Field checks Carry it to site — no power unit needed.
  • Commissioning Confirm each valve before first start-up.
  • Preventive maintenance Catch a sticking spool before it stops production.
  • Training Show trainees how proportional valves respond.

Common questions

Is PVC one product or several?

PVC is a series of kits. Non-OBE models are for valves without on-board electronics (with or without position feedback); OBE models are for valves with on-board electronics, in Version A (without PLC) and Version B (with PLC). More models are in development.

Which valve brands does it work with?

Any brand. The PVC drives the valve directly, so it doesn’t depend on the manufacturer — only on the valve being within the kit’s voltage and current limits.

Do I need hydraulic pressure to test a valve?

No. The PVC drives the valve electrically, so you can check it on a bench without a power unit.

How do I know which model I need?

Use the two questions above, or send us the valve’s make and model number and we’ll tell you.

Can I see it working on my own valves?

Yes. Book a demo and an HVK engineer will bring a PVC to your plant.
