Product Detail

The Heavy Calibre Heavy Hammer Swing Check Valve is a critical safety device engineered for large-scale municipal water, power plant circulation, and industrial pumping stations. In large-diameter pipelines, sudden pump shutdowns create massive kinetic energy and destructive water hammer surges. Equipped with a robust counterweight (heavy hammer) and lever mechanism, this valve ensures controlled, silent closure. The gravity-assisted design provides a fail-safe operation without needing external power, protecting upstream pumps and piping from catastrophic mechanical shock.

Design Description

Dual-Stage Hydraulic Slow-Closing: Can be integrated with a hydraulic damper to fast-close (approx. 80%) to stop backflow, then slow-close (final 20%) to eliminate water hammer.
Gravity-Driven Fail-Safe: The heavy hammer utilizes gravity to assist the disc in closing, operating flawlessly without external electrical or pneumatic power.
Visual Disc Position Indication: The external lever directly reflects the internal disc angle, allowing operators to verify the flow status at a single glance.
Low Pressure Drop (Full Bore): The streamlined swing disc design opens fully into the valve cavity, maximizing flow capacity and minimizing pumping energy costs.
Wear-Resistant Hard-Faced Seating: Available with stainless steel or Stellite hard-faced seats to resist high-velocity erosion in large volume pipelines.
