    Pressure Rated: PN16/PN25 or Class 150/300.
    Blow-Down Valve Option: Purge accumulated debris without stopping flow.
  • Ductile Iron Control Valve (Globe Type) | Pressure Reducing & Flow Regulating
    Pilot-Operated Design: Precise control of pressure, flow, or level.
    Globe Pattern Body: Excellent throttling characteristics.
    Available Functions: Pressure Reducing (PRV), Sustaining (PSV), Flow Control (FCV), Altitude (ALV).
    Hydraulic or Electric Pilot: No external power needed for hydraulic pilots.
    Diaphragm Actuated: Smooth, stable regulation.
    Bolt-on Seat: Easy maintenance.
  • Ductile Iron Threaded Water Meter | Compact for Residential & Small Commercial
    Threaded Connection: BSP or NPT threads for easy installation on small pipes (DN15-DN50).
    Multi-Jet or Volumetric Type: Reliable accuracy at low flow rates.
    Dry Dial Register: Magnetic drive prevents water from fogging the display.
    Compact & Lightweight: Easy to install in meter boxes or tight spaces.
    Horizontal or Vertical Installation: Available with universal body.
    NSF / WRAS Certified Options: For drinking water applications.

    Double Orifice Design: Large orifice (for pipeline filling) + small orifice (for pressurized release).
    Automatic Operation: Float-controlled mechanism — no manual intervention needed.
    Prevents Pipeline Collapse: Releases accumulated air pockets that cause bursts or flow reduction.
    Vacuum Breaking: Admits air when pipeline drains to prevent negative pressure collapse.
    Ductile Iron Body: Corrosion resistant with epoxy coating.
    Flanged or Threaded Connection: Available in both styles.
  • Ductile Iron Basket Strainer (Tee Strainer) | High Debris Capacity for Pump Suction
    Basket / Tee Type: Larger debris holding capacity than Y-strainers.
    Easy Cleaning: Removable basket lifts out from top cover.
    Low Pressure Drop: Large open area of basket reduces flow resistance.
    Perforated or Mesh Basket: Options for coarse or fine straining.
    Blow-Down Port Option: Drain debris without disassembly.
    Ideal for Pump Suction: Protects pumps from large debris (rags, sticks, stones).
