OCV Founded – Innovating Fueling Systems

Over 70 years ago, Tex Radford founded OCV Control Valves in Tulsa, Oklahoma, expanding his machine shop to build valves for the fueling industry. The first OCV valve, designed for aviation fueling stations, set the standard for quality and reliability.

DOROT Valve Factory Founded

In 1941, the founders of Kibbutz Dorot identified a need for irrigation valves to support agriculture but lacked funds to buy them. They sold a truck to finance the purchase of essential equipment that allowed them to produce their own 2-inch valves in a small shed. By 1946, they had built the first DOROT factory building.

Range of Y Pattern (Oblique) Valves Developed

One of DOROT’s first significant developments was the patented Y Pattern (Oblique) Valve, which was widely adopted by leading companies in the  industry. This valve became the foundation for hydraulic control valves, serving as a model for other manufacturers as well.

Setting the Standard: Meeting Every Challenge Since Day One

DOROT’s first valves were made for use on the kibbutz, but soon a team member took them to the city, selling from a heavy backpack. There, he encountered diverse irrigation needs, sparking the company’s a commitment to innovation and a tradition of adapting its products to meet every demand – a legacy that defines us to this day.

A.R.I Optimal Flow Solutions Factory Founded

A.R.I.’s journey began with a group of visionary young pioneers on a kibbutz, who established a small business to support their community’s economy. What started as a modest venture has evolved into a global leader in air and water management solutions, bridging the gap between suppliers and customers, and setting a new standard for reliability and innovation in liquid transmission system protection.

The World’s First Direct Diaphragm Sealing Valves Introduced

Operated by pipeline pressure and designed for a range of control applications, the DOROT S100 series was a groundbreaking valve that revolutionized the market and continues to shape control valve technology today.

The World’s First Composite Material Air Valve Launched

The A.R.I. D-040 Barak sparked a revolution in the industry. This groundbreaking valve, with its unique rolling seal patent to prevent water hammer, set a new global standard for air valves and marked a significant advancement in valve technology.

A.R.I. - Pioneers of the Air Management Revolution

A.R.I. has been instrumental in revolutionizing air management by bridging the knowledge gap in hydraulic transmission systems. Through collaborations with top universities and researchers, A.R.I. has conducted groundbreaking studies that redefined air’s role in hydraulic systems. These influential studies have laid the foundation for the field, inspiring innovative products, optimizing hydraulic systems, and driving a global transformation in air management.

Revolutionizing Wastewater Management: The Launch of the A.R.I. D-020 Combination Air Valve

The introduction of the A.R.I. D-020 Combination Air Valve transformed the wastewater industry by enabling, for the first time, the use of air valves in sewerage systems. Designed specifically for systems with liquids carrying solid particles, the A.R.I. D-020 combines an air & vacuum orifice with an air release orifice in a single body.

World's First Unique PVC Valve with Direct Pipeline Bonding

DOROT 56, a hydraulic control valve made of plastic, is one of the first in the world with diameters ranging from 3 to 6 inches. It could be directly bonded to pipelines, eliminating the need for adapters. Revolutionizing pressure control in open-pit mines and leaching operations, it offered a more accurate, reliable, and cost-effective solution compared to previously available options.

World’s First Plastic Sewerage Air Valve: The Lightweight, Maintenance-friendly A.R.I. D-025

The A.R.I. D-025 made history as the world’s first plastic air valve for sewerage systems, combining the proven performance of the A.R.I. D-020 with additional groundbreaking advantages. Its lightweight design and innovative quick-release clamp allow for easy, on-the-spot maintenance without removing the valve from the pipeline.

A Breakthrough in Filtration: The World’s First Double-chamber Back-flushing Valve

Designed to support various filtration systems—from screen and disc filters to media and sand separators—the innovative DOROT model 52 valve, enables efficient cleaning by allowing quick transitions between operational modes. This valve sets a new standard for reliability and efficiency in filtration maintenance across residential, irrigation, and industrial systems.

DOROT S300: A New Benchmark in Control Valves

The DOROT S300 is a pioneering hydraulic control valve, engineered to exceed the toughest water system requirements. With its unique ability to regulate near-zero flow across all sizes—without extra components—and minimal head loss when fully open, the S300 redefined industry standards for efficiency and reliability.

Launching the University: Empowering Industry Professionals

Through a strong sense of responsibility for the preservation of resources and the wider world of water, we began to share our professional knowledge about water management, acquired over decades, with colleagues in the industry. This, combined with our customer-driven approach, has led us to establish what is now known as Aquestia University, hosting webinars, training and large seminars in various related fields.

The Birth of Aquestia: Three Industry Leaders, United

In 2020, A.R.I. Optimal Flow Solutions merged with the previously-merged OCV Control Valves and Dorot Control Valves, forming a new company: Aquestia. Combining these three successful brands into one entity provides a vast array of product solutions under one roof, ensures a high level of global customer service, and offers unparalleled expertise and innovative technologies.
