Reliable, precision machined and low torque design in general requiring no maintenance through out service life.
-
Designed to meet IS 3224:2002 and EN ISO 10297:2006.
-
Design provides O-ring backed by high durometer elastomer back up ring for external tightness. Thrust washer between the top spindle collar and gland nut further protects the O-ring at high pressure. Combination of simultaneous metallic and non metallic sealing designed to resist acetylene flashback.
-
Gland nut abutts at the inner end with the valve body ensuring metal to metal seal eliminating need to retighten the gland nut.
-
Spindles machined from naval brass for toughness and wear resistance except top spindle for key operated valves which is machined from SS-304 rods and designed to fail safely, below square at a closing/opening torque between 65-70 Nm. This ensures that in case excessive torque is applied on the operating mechanism; the spindle shears before damaging the bottom spindle and the valve body.
-
Bottom spindle threads, thrust washer, 'O' ring and back up ring are lubricated to eliminate seizing and galling.
-
Valve body withstands impact strength of 400 J making it suitable for cylinder package mass of 111 kgs, if used without valve guard.
-
Valves provided with Stainless steel filter at inlet.
