SELF CLOSING LPG VALVES: LPG Cylinder Valves are 25.6 mm dia Self Closing Type with Vertical outlet and incorporating vertical spring actuated spindle. Valves inlet and oulet confirming to Kosan Teknova Drawing. Valve oulet is fitted with “Joint Packing” Valves confirm to Bureau of Indian Standards Specifications IS:8737 :1995 and are duly inspected and certified/marked by BIS. THe material of the valve housing (valve body) comply with the physical and chemical properties of Brass as per IS:8737-1995 (latest)SPECIFICATION FOR SAFETY CAP: Safety Caps are of “DUPONENT DERLIN 500/900/1700P OR, CELCON M-90 / M-140 OR TENAC-5010 (all virgin materials)” approved by Oil Industry Technical Committee (OITC) suitable for fixing at the oulet of Self Closing Compact Valve (25.6mm dia outlet) Material for Safety Caps is of Virgin Material. Safety Cap for Self Closing Compact Valve for LPG Cylinder is complete with spring and soft twin nylon chords with knot fused to ensure that it does not get opened under any circumstances. Cap Spring is tempered in such a way that it should facilitate easy fitment/removal and it should not become loose after at least 1000 operations of opening and closing. Nylon Cord : Twin Cord of diameter 2.50 mm (combined) & 150(+/-5)mm long. Spring: Stainless Steel. Safety Caps are moulded using Automatic Injection moulding machines only and not by semi-automatic/hand moulding machines.Quality and Assurance: Raw material for Valves is tested minimum once in a quarter through an independent NABL accredited labratory for conformity of chemical composition of raw material to IS 8737:1995. A copy of test certificate from independent testing labratory is sent along with each consignment of the valves. Calibration of all testing/measuring equipment is done as per BIS scheme of testing and Inspection. Rubber Components are regularly tested for meeting specifications as per Kosan Technova Technology document Punching on the Valve Hexagonal faces is clear and strictly in line with the drawing requirements.
