Packing Nut On Valve

The locking nut on valve is a key fastening and sealing adjustment component used in valve stuffing boxes, suitable for medium and high pressure, frequent opening and closing conditions.

Stable Sealing: Utilizing high-strength metal materials and a precision thread structure, it can uniformly apply axial preload, ensuring stable pressure distribution on the packing.

High Thread Precision: The threads are precision-machined and tolerance-controlled, ensuring tight meshing and uniform stress distribution.

Pressure and Corrosion Resistance: Available in carbon steel, stainless steel, or alloy steel, offering pressure and corrosion resistance.

Industrial Valve Systems: Achieve stem sealing by compressing packing under medium to high pressure conditions.

Oil & Gas and Petrochemical Pipelines: Prevent media leakage under pressure fluctuations and frequent opening and closing conditions.

Chemical Plant Valves: Maintain stable packing seals in corrosive media environments.

Power and Steam Systems: Maintain long-term valve sealing performance under high temperature and high pressure conditions.

Raw Material Selection and Cutting: Carbon steel, stainless steel, or alloy steel are selected to ensure pressure resistance and corrosion resistance.

CNC Turning and Thread Machining: Precise control of thread angles and tolerances improves meshing accuracy and stress stability.

Heat Treatment: Improves material strength and fatigue resistance, preventing thread deformation or failure.

Surface Treatment: Performs rust-proofing or corrosion-proofing treatment to extend service life.
