Flow Control Division

Flowserve is a leading global supplier of flow control products for process systems, including automatic control valves, quarter-turn valves, nuclear gate and check valves, intelligence systems for valves, actuators and valve automation systems, and related components.

Founded in 1959, Flowserve's Worcester Control products are recognised today as one of the world's leading brands.

Worcester can claim what is arguably the most comprehensive product range of any ball valve manufacturer in its field. From standard flanged ball valves to both ANSI and DIN specifications in reduced and full bore, to three piece valves for cryogenic, high pressure, steam, diverter or sampling duty, or high integrity valves, multi-way designs, modulating controls or customised solutions to specific user problems, we supply valves throughout the world for virtually any application.

Recently, Worcester became the first UK ball valve manufacturer to gain PED approval.

Flowserve's line of Automax valve automation systems includes a broad range of rack & pinion, scotch-yoke and electric actuators for mounting on quarter-turn ball, plug and butterfly valves. In addition to a wide variety of actuator styles, the Automax product line offers a complete valve automation package with a comprehensive range of positioners, solenoid valves, NAMUR accessories, limit switches, and engineered solutions to the user's mounting hardware needs. With technology moving toward fieldbus communication, Flowserve offers Automax smart switch products for use with digital communications.

The Duriron Corporation was founded in 1912 by Pierce D. Schenk and two associates, William F. Hall and Richmond Pitman to supply corrosion-resistant castings for the chemical industry. The company name derives from its patented alloy Duriron, which rapidly became an industry standard. During the 1920s and 1930s Duriron became a nationally-established producer of pumps and valves. The company also began a move toward off-the-shelf sales of its pumps and valves during this time. This policy would begin to reap great returns in the 1940s as Duriron's products became more widely accepted in the chemical industry. The name Durco was given to the pump and valve products to emphasize the superior materials that they were made of. Today, Flowserve Durco valves are among the finest produced for the process industry.
