What Aqua Environment does
Aqua Environment Co., Inc. is a privately held, founder-led manufacturer of high-pressure valves, regulators, and flow control components for gas and liquid service. The company designs and manufactures products rated for 6000-7000 psi service in 1/4" or 1/2" pipe configurations, with select models such as the 1607 relief valve rated to 7500 psi. Operations are consolidated at a single manufacturing facility in San Rafael, California (3100 Kerner Blvd, Ste N), north of San Francisco, where products are designed, machined, assembled, tested, and shipped directly to customers.
The product portfolio spans reducing regulators (415 and 873 series), metal-to-metal seat back pressure regulators, relief valves, sequence valves for cascade filling, dome-loaded and amplifying/pilot-operated regulators, temperature-compensated pressure switches, check valves, flow fuses, bleed valves, inline filters, SCBA adapters, and visual indicators. Technical differentiators include proprietary metal-to-metal seat technology that resists regulator freeze-up during high-pressure gas expansion, optional heating manifolds for extreme conditions, and standard/high-flow component variants supporting systems from small-scale (15 SCFM and below) up to large-capacity industrial installations. All products are proof tested to four times or greater rated working pressure and are designed to ASME Vessel Code Section 8, with an in-house audited quality program modeled after ISO9001 and pre-shipment flow and leakage verification with certificates of conformance available on request.
The commercial model is a B2B direct-sales operation targeting industrial, commercial, military, firefighting, and diving customers across six identified vertical use cases: fire fighting, scuba diving, natural gas (CNG delivery), fill stations (cascade banks), commercial/industrial (pump seals, cryogenic control, injection molding), and military. Pricing is quote-based and not publicly disclosed, with revenue derived from one-time hardware sales, OEM repair kits and replacement parts, and ancillary services such as pressure-set certificates. Customers engage via phone (415-453-8157), email ([email protected]), and a website product catalog; broader discovery is supported by a ThomasNet industrial marketplace listing. The company was established in 1967, pivoted to high-pressure valve manufacturing in 1976, and was incorporated in California in 1981 under founder Don Slack, who continues to serve as President.
