128-5015 This has to be one of the coolest and simplest stream lined inventions to come along in recent times. High water pressure spikes plague numerous boats and cause catastrophic engine damage. Until now your only option was an independent pressure relief valve that you then had to plumb to a water dump to discharge the water. Thanks to the Hardin Marine team they have taken the best high flow water valve design and integrated it into a common water dump.
These dumps feature a sleek design as well as unique wrench flats machined into the body aiding in assembly during a one person installation. Constructed from 316L stainless steel. This model provides a 1/2 NPT female thread allowing for any arrangement of possible fitting and hose connections. The unit features a stainless tulip style valve that is spring loaded. The units come preset at approximately 10psi.
- 1-7/16" Flange Diameter
- 1/4" Flange Height
- 1-1/8" Shaft Outside Diameter
- 3" Overall Length
- 1/2" NPT Internal Thread
- Pre-set at Aprox. 10lb Pressure Relief, not adjustable.
- Approx. Flow Rate (gallons per minute) 10 psi=7 GPM, 15 psi= 13 GPM, 20 psi=19 GPM
