Learn MoreAn unloader contains a check valve that traps pressure between the closed downstream device (shut-off gun) and the unloader, causing an internal piston to open, allowing the pump to unload at low pressure. When the shut-off gun is opened back up, the system will return to operating pressure. Regulators and unloaders each have their benefits.
