Manufacturing Process
A meticulous, quality-driven approach ensures industrial valves meet international standards for performance, durability, and reliability. Here’s a detailed overview of the manufacturing stages:
Raw Meterial
High-quality materials such as Cast Iron (ASTM A126), Ductile Iron (ASTM A536), Cast Steel (ASTM A216), and Stainless Steel (ASTM A351) are selected based on the type and application.
Valve seats use premium elastomers like Nitrile, EPDM, Viton, Hypalon, Silicon, or Neoprene, ensuring tight sealing and corrosion resistance.
Casting & Forging
The valve body and components are manufactured using either casting or forging, depending on the material and design specifications.
Precision molding techniques ensure dimensional accuracy and structural integrity.
Machining & Processing:
- CNC machines and lathes are used to achieve precision in components.
- Key processes include drilling, boring, threading, and shaping of internal passages to meet international standards.
Assembly & Lining
Integral rubber or PTFE linings are molded into the body for tight sealing and bi-directional flow.
Seats, discs, shafts, and other moving parts are assembled with attention to fit and function.
Coating & Surface Treatment
Anti-corrosion coatings such as Teflon, powder coating, and nylon coating are applied.
Stainless steel or epoxy-coated options are available for enhanced durability and resistance to harsh environments.
Quality Inspection & Testing
Hydrostatic and pneumatic pressure tests (as per API 598 / BS EN 12266-1) ensure that products meet pressure and leakage standards.
Dimensional accuracy checks conform to ISO 5752, API 609, and IS 13095.
Seat tightness and vacuum sealing are tested to PN 10 / PN 16 standards.
Packing & Dispatch
Each unit undergoes a final cleaning, lubrication (if required), and protective packaging.
Proper documentation, labeling, and certification accompany the shipment for quality assurance and traceability.
