Designed for easy, in-line maintenance, the SF4 is a robust 3-piece bolted, forged valve and is a great choice for any on-off service application. Designed according to the ASME B16.34, it is a durable and reliable quarter-turn valve. It is available in low temperature carbon steel, dual certified A105N-LF2, offering options to suit different application requirements. The valve features bi-directional sealing with C-RPTFE soft seats and is available in both full and reduced bore configurations. It is very versatile, easy to operate, and incorporates low fugitive emission, fire safety, and antistatic design features.
