Frequently Asked Questions

Can I control the motion of a load with a pilot-to-open check valve?

A pilot-to-open check valve is a load holding valve, not a motion or over-running load control valve. It is not capable of dissipating energy in a controlled fashion. A pilot-to-open check valve is either open or closed; it does not modulate. If you try to use a pilot-to-open check valve to control an over-running load, a severe ratcheting movement of the actuator is likely to occur.
