The new 537 manually operated globe valve (photo) uses the same valve body as the company’s 534 and 532 actuator designs. Valve bodies in nominal sizes DN 15–50 in cast-stainless-steel 1.4408 and SG iron GGG 40.3 (EN-GJS-400-18-LT) are available. The maximum operating pressure is 25 bar for DN 15–40 sizes, and 16 bar for DN 50. Standard versions can handle temperatures up to 180°C, and the PTFE gland packing is suitable for steam. — GEMÜ Gebr. Müller Apparatebau GmbH & Co. KG, Ingelfingen-Criesbach, Germany
