SB Single Block Valve

FITOK SB (single block) isolation valves offer a compact solution for isolating process lines, with a bleed port that allows residual pressure to be released safely. Available in LF2 carbon steel and 316 stainless steel, they handle temperatures from –54 °C to 649 °C, depending on the model. They can be configured with welded, RF/RJ flanged or NPT threaded connections, adapting to multiple piping layouts. All SB valves are tested according to API 598 and can be supplied with advanced options such as API 607 fire-safe, EN 12266-2 anti-static design and NACE MR0175 compliance for H₂S service. Their compact design and reliability make them a safe choice for systems where isolation with venting is essential.
