Our history is testament to our commitment to the natural gas industry. The Model 1 was just the beginning. In 1985, we introduced electrofusion technology to the natural gas market. In 1987, Kerotest was the first approved polyethylene valve supplier to British Gas (now National Grid). A year later, we offered the all-welded steel ball valve line – the ANSI Class 150 Weldball.
Then in 1989, primarily to increase our commitment to this market, we opened our second manufacturing facility in Mansura, Louisiana where we would invest almost $5 million in new technology. And in 1991, to ensure a consistently high level of product and service in our plants, engineering departments and administration, we adopted the Total Quality Management philosophy. Two years later in 1993 we celebrated 30 years of continuous service for the Model-1. Then in 1994, we introduced the ANSI Class 300 Weldball, an expansion of the popular all-welded steel ball valve design. Another first was introduced in 1994 with the Charlotte Universal Electrofusion Control Box.
Today, we sell valves to literally every gas company in the U.S. Natural gas is part of our history and will be a big part of our future.
KEROTEST VALVES are among the best you can buy anywhere in the world. As an Employee Stock Ownership Plan (ESOP) company, we don’t just talk about quality, we produce it, because everyone here is empowered to give you the best product, the best value and the best service.
