A new range of lift check valves from this company uses a clamp-in-place seat design that allows easy inline maintenance and helps avoid plant downtime. New valve models are constructed using cast iron, carbon steel, stainless steel and SG iron, and are suitable for a wide range of applications. The valves prevent reverse flow in pipelines carrying most types of liquid, as well as steam and gases. The valves protect equipment from pressure surges associated with hydraulic forces, such as water hammer. The product line is fabricated for horizontal pipeline installations for arduous applications, and provides higher flowrates than comparable disc check valves, says the company. — Spirax Sarco Inc., Blythewood, S.C.
