valve. Once the Unloading Valve has sequenced and is ready to reset, the override valve must be opened and held open for approximately 5 seconds to relieve gas pressure in the bonnet. Monitor the pressure gauge until it reduces to zero. At this point the Unloading Valve is reset and the override valve should be released. FIG. 2 CAUTION:

An 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.

A trapped pressure unloader is a simple valve with a spring mechanism mounted in a Brass or stainless steel body. There is a channel within the body that gives water access to the back of a piston. When the trigger is released the pressure against the piston increases and pushes the spring open to allow the water to pass into the bypass.
