ZECO Valve | W&O to Distribute LESER Safety Relief Valves

What is W&O?

W&O, a global supplier to the marine and upstream oil and gas markets for pipe, valves and fittings, valve automation, and engineered solutions, has partnered with LESER in an exclusive distribution agreement to bring its safety relief valves to the United States maritime industry. This marks W&O’s first exclusive distribution agreement with a direct original equipment manufacturer of safety relief valves in the company’s 40-year history.

“W&O is excited to announce this partnership with LESER, and to do so at one of the industry’s marquee events, the International WorkBoat Show”, said Michael Hume, president and CEO of W&O. “The LESER safety relief valves are German-engineered and manufactured, and will be an excellent addition to the tank venting solutions we currently bring to our customers. This partnership is a natural fit for W&O, as LESER is equally committed to meeting customer needs, providing the highest quality product and engineering solutions to fit specific applications.”

The W&O and LESER partnership will prove very beneficial to customers for numerous reasons, including: short delivery times due to high stock of raw material and finished goods at the Charlotte, North Carolina, LESER facility, a variety of solutions from eight product groups and 40 safety relief valve types, and customer support offered by both companies.
