No. SS2-8-0 Top-Guided Single Seated Control Valves (Rating : ANSI 0 or Less) OVERVIEW Model VST control valves are suitable for use in fluid with slurry because of its one side guiding construction. Guide portion is solid and has sufficient sliding area against abrasion. The body construction allows simpler disassembly, faster checking of trim, and easier parts replacement. Also, valve plug and seat ring can be fitted without mounting the bonnet.
