5 PSI Hastelloy Springs Reliever with Viton Gasket

The ChemPlas DASH-1 “RELIEVER” will at once sense a tank pressure buildup or internal vacuum and “relieve” it. In a catastrophic fall or tip over, the DASH-1 “RELIEVER” is completely fail safe. The unit has an indefinite working life and will be replaced if found defective within two (2) years.
Injection molded from virgin ultra-violet stabilized Polypropylene, the “RELIEVER” has superior chemical resistant properties.
The Pressure/Vacuum “RELIEVER” is available in two (2) versions. Model #-050 is set to operate at pressures between 3.5 and 5.5 PSIG. Model #-100 is set to operate between 10 and 12.5 PSIG. Vacuum releases at .5 PSI on both models (for gravity flow only). Both models thread into 2” Straight NPT. Lock nuts are available upon request.

We offer a variety of O’rings and springs to suit each individual application. Our standard O’ring is Viton (brown) for maximum chemical resistance. EPDM, BUNA and EPDM/FDA food grade are available upon request. Our standard spring is wound from 316 Stainless Steel. We also offer Teflon coated 316 Stainless as well as Hastelloy C which is one of the most universally corrosion-resistant alloy available.
