\nApplication:\u200c Designed primarily for use as tank source valves and pipeline valves for LPG (Liquefied Petroleum Gas) systems.<\/p>\n

2. Key Specifications\u200c<\/strong><\/p>\n

Fluid:\u200c LPG (liquid and gas)
\nDesign Pressure:\u200c 2.4 MPa
\nDesign Temperature:\u200c -5\u00b0C to +70\u00b0C
\nConnection:\u200c JIS20K RF
\nBody Material:\u200c SCPH2
\nNote:\u200c This is the standard specification. Confirm actual specifications from your order documents.<\/p>\n

3. Important Handling & Installation Notes\u200c<\/strong><\/p>\n

Do not\u200c lift the valve by its handwheel or subject it to impacts.
\nRemove the flange guard\u200c attached to the flange face \u200cbefore connecting\u200c the valve to the piping.
\nClean pipe\/flange surfaces thoroughly and use a sealant-coated gasket suitable for LPG.
\nTighten flange bolts diagonally and evenly.<\/p>\n

4. Operation & Maintenance\u200c<\/strong><\/p>\n

Operation:\u200c Turn the handwheel \u200cclockwise to close\u200c, \u200ccounter-clockwise to open\u200c. Avoid using wrenches or excessive torque.
\nMaintenance:\u200c Regularly check for leaks.
\nGland Leak \u2192 Replace V-shaped packing.
\nBonnet Joint Leak \u2192 Replace gasket.
\nStiff\/Squeaky Operation \u2192 Clean, lubricate spindle; if persists, replace V-shaped packing.<\/p>\n

5. Disassembly & Reassembly (Summary)\u200c<\/strong><\/p>\n

Important:\u200c Ensure valve is depressurized before starting.
\nKey Steps:\u200c Follow diagrams. Typically involves removing handwheel, gland nut, internal packing parts (spring, gasket, V-shaped packing, O-ring), bonnet, and seat packing.
\nKey Reassembly Rules:\u200c
\nClean all parts.
\nReplace all seals (gaskets, V-shaped packing, O-rings) with genuine parts.\u200c Lightly apply LPG-compatible grease to V-shaped packing and specified gaskets\/O-rings.
\nDo not apply sealant\u200c to the main bonnet gasket (“24” for 15A-50A, “27” for 65A\/80A, “14” for 100A\/150A).
\nFor sizes 65A-150A, apply LPG-compatible (high-load) grease to bonnet\/spindle threads.
\nAssemble with the valve disc in the \u200cfully open position\u200c.
\nUnion Nut Torque (15A-50A):\u200c See values in table (e.g., 15A: 140-180 N\u00b7m).<\/p>\n
