Gresswell

Gresswell Valves was founded in Birmingham in the 1930's by the Hayes family and built a reputation for a wide range of quality valves and related products.

Gresswell Valves have been providing an essential supply of pressure safety/relief valves to industry for almost 80 years. Manufactured in bronze and stainless steel with a wide range of pressure settings (0.3 - 21 bar) Gresswell Valves can be supplied to various specifications to provide safety from potentially lethal over pressure, e.g. boiler systems, pumps, shipping, oil and gas industries and enclosed pressurised systems.
