154 HIGH PURITY SERIES ※ PP and PVDF ball valves of the Socket End type and PVDF ball valves of the Spigot End type are welded valves. Notes : There is a dead space in a ball valve. Volatile liquids, such as a hydrogen peroxide(H2O2)and Sodium hypochlorite (NaClO) may vaporize in the dead space, thus causing an abnormal pressure increase in the valve. (Important: Gas is compressible. Thus if pressure rises abnormally, the valve can burst ejecting dangerous fragments.) �L※ See drawings on page 16 (only for flanged end type) FEATURES BALL VALVE TYPE 21・21α 15mm - 100mm(1/2inch - 4inch) MATERIAL AND WORKING TEMPERATURE Body material Working Temperature ℃（°F） Max.Working Pressure(at R.T.)

The BALL VALVE TYPE 21 can easily be converted from the manual to automatic without replacing the body. ■ Simple Installation on Panel Piping New bottom stand with an insert hole allows the valve to be secured on bench or panel only by inserting a metallic insert. ■ Double-O-ring The stem uses a double-O-ring, sealing arrangement improving durability sealing performance. The upper O-ring groove is deeper than the lower O-ring groove. Because of this design, the stem would break first at the upper O-ring groove, acting as a back up seal. ■ Multi Functional Handle Removing the handle and placing the raised lugs into the carrier allow for easy disassembly of the valve. *The handle has other colors. (blue, white, yellow)(Option) ■ Locking Device (Option) The handle lock can be done by full-open (close) PARTS & MATERIALS TRUE UNION DIAPHRAGM LAB COCK PANEL MOUNTING BALL VALVE TYPE21 VALVE TYPE14 HP-PVC PIPES AV GASKET MULTI-JOINT AV FLANGE AV PREFAB JOINT HP-PVC FITTINGS & FITTINGS
