Top-Guided Single Seated Control Valves (Rating : ANSI 600 or Less)

Transcription

1 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. Model VST SPECIFICATIONS Body Type Straight-through, cast globe valve Nominal size 1½, 2, 2½, 3, 4, 5, 6, 8, 10, 12 inches Pressure rating JIS 10K, 16K, K, 30K, K ANSI Class 150,, 0 JPI Class 150,, 0 End connection Flanged end Connection type Pressure rating Applicable standard JIS10K JIS B FF ANSI Class 125 ANSI B JPI Class 125 JPI-7S JIS10K JIS B JIS16K JIS B JISK JIS B RF JIS30K JIS B JISK JIS B ANSI Class 150,, 0 ANSI B JPI Class 150,, 0 JPI-7S RJ ANSI Class 150,, 0 ANSI B JPI Class 150,, 0 JPI-7S Material Carbon steel (SCPH2), Low alloy steel (SCPH21, 32, 61), Stainless steel (SCS13, 14) and Other alloy steel Gland type Bolted gland Bonnet Plain bonnet (0 to 0 C) Radiation finned bonnet (over 0 C) Extended bonnet (0 C or less) Bellows seal bonnet (-30 to + C, {10 kgf/ cm 2 } max.)
