SS1-CVG200-0100 Standard Combination of Gland Packing for Control Valves 1 Overview Gland packing for control valves is required seal performance to prevent the leakage from valve stem part and function to minimize frictional resistance during operation It is necessary to pay full attention to selection of gland packing because frictional resistance during operation affects dynamic behavior of control valve Gland packing selection table Packing No. Material Application fluid Packing basic specification Grease Presence of asbestos Structure diagram Fluid temperature range Maximum working pressure (MPa) *1 For high temperature (no less than 500‹C) P6610CH+M8590 Expanded graphite packing + Carbon fiber reinforced expanded graphite packing High temperature and high pressure (Strong acid, strong alkali and toxic gas are inapplicable) 500‹C to 566‹C 43 Yes No ‡@ T2200+P6710CH (TYPE2) Expanded graphite packing + Steel wire reinforced expanded graphite yarn packing High temperature and high pressure (Strong acid, strong alkali and toxic gas are inapplicable) 500‹C to 566‹C 43 Yes No ‡A For high temperature (less than 500‹C) P6610CH+P6528 Expanded graphite packing + Expanded graphite yarn packing High temperature and high pressure (Strong acid, strong alkali and toxic gas are inapplicable) 230‹C to 500‹C 43 Yes No ‡B Type AGVB/AGVM only Graphite yarn (P6610CL+P6722) Expanded graphite packing + Aramid fiber reinforced expanded graphite yarn packing High temperature and high pressure (Strong acid, strong alkali and toxic gas are inapplicable) 230‹C to 400‹C 43 Yes No ‡C For standard or Low temperature PTFE Pure PTFE packing General use or oil free (Various chemical, acid and alkali) -196‹C to 230‹C 10 No No ‡D PTFE yarn (P4519) PTFE fiber yarn packing with carbon fiber core General use (Various chemical, acid and alkali) -17‹C to 230‹C 10 No/Yes No ‡E PTFE+V7233 Pure PTFE packing+ PTFE fiber yarn packing General use or oil free (Various chemical, acid and alkali) -196‹C to 230‹C 10 No No ‡F PTFE+TK2006 Pure PTFE packing+ PTFE braided packing General use (Various chemical, acid, alkali and LNG) -196‹C to 230‹C 10 No No ‡G For vacuum PTFE(Dir.+Rev.)

The maximum operating pressure is performance peculiar to gland packing. When gland packings are attached to valve, please use within range of valve's pressure and rating temperature. *2. Gland packings not listed on the selection table may be used depending on process conditions. Consult us about specifications of gland packings not listed in the table. As a rule, be sure to use under listed operating conditions (fluid, temperature and pressure). Never use gland packings except listed operating conditions, or failure, problems and other accidents could occur. We shall bear no responsibility for any damages resulting from improper use by customer. 1st edition 8 2 Specifications are subject to change without notice. gThis product is designed for general industrial use.h
