The Ultimate Guide to Cast Iron Valves

Discover our extensive range of high-performance Cast Iron valves (ASTM A126 Class B) built for Water, HVAC, and Sewage applications. Engineered for PN10 and PN16 pressure ratings with ISI Marks & Water Board Approvals.

Why Choose Cast Iron Valves?

Cast Iron valves are a cornerstone of modern pipeline infrastructure. Manufactured to the precise ASTM A126 Class B standard, these valves offer unmatched rigidity, cost-efficiency, and excellent noise and vibration dampening capabilities. They are universally specified for low-to-medium pressure applications such as Municipal Water Supply, HVAC Systems, and Sewage pipelines.

Pressure Ratings: PN10 & PN16

Our Cast Iron valves are engineered to perform reliably under standard pipeline pressures. We offer products specifically tested for PN10 (10 Bar) and PN16 (16 Bar) pressure classes. This makes them ideal for safe, long-term operation in commercial buildings and civil water management systems.

Applications: Water, HVAC, and Sewage

  • Water Treatment & Distribution: Ideal for isolation and flow control in large municipal water grids.
  • HVAC Systems: Widely used in chillers, cooling towers, and boiler feed lines for reliable climate control.
  • Sewage & Wastewater: Rugged enough to handle non-corrosive slurries and treated sewage water.

ISI Marked & Water Board Approved

At Supreme Valves, trust is built on certification. Our Cast Iron valves boast the prestigious ISI mark and are officially approved by major municipal Water Boards across India. This guarantees strict compliance with dimensional, pressure, and safety standards, ensuring complete peace of mind for contractors and municipal bodies.
