Description

The KS 10K Cast Iron Lift Check Valve is a reliable, automatic valve designed to prevent backflow in vertical piping systems. Unlike swing check valves, the lift check valve requires vertical installation and uses a guided disc that lifts off the seat to allow flow. Constructed from durable GC200 cast iron with a specialized brass seat ring, it meets rigorous standards for safety and performance, making it essential for protecting downstream equipment in vertical lines.
Technical Specifications:
  • Pressure Class: 10K (Approx. 10 kgf/cm² / PN10)
  • Size Range: DN15 – DN100 (Standard Range for Lift Check Valves)
  • Applicable Medium: Water, Steam, Oil (Non-corrosive fluids)
  • Operating Temperature: -10°C to 220°C (Cast Iron Range)

Key Product Features:
  1. Vertical Flow Design: Specifically engineered for vertical pipelines where the flow direction is upward, ensuring the disc lifts correctly against gravity.
  2. Durable Body: Constructed from GC200 grey cast iron, providing high strength and resistance to deformation.
  3. Premium Seat Ring: Equipped with a ZHMn58-2-2 (Manganese Brass) seat ring to ensure a tight, leak-proof seal and long service life.
  4. Guided Disc Mechanism: The disc is precisely guided to prevent tilting and ensure consistent sealing performance.
  5. KS Compliance: Manufactured and tested in strict accordance with KS standards for 10K pressure ratings.
Applications:
Ideal for Vertical Water Supply Lines, Boiler Feed Systems, HVAC Networks, and General Industrial Piping. Specifically suited for installations where space constraints require a compact vertical valve design to prevent reverse flow.
