Collection: Unloaders
Two prevalent types include the trapped pressure unloader valve and the flow-actuated unloader valve. In the trapped pressure unloader valve, water is provided access to the back of the pistons. Releasing the trigger leads to an increase in pressure, causing the spring to open.
