DIN Cast Iron Lift Check Valve H41H-16

Technical Requirements:
  1. Design & Manufacture: EN 13789
  2. Face-to-Face: BS EN 558-1
  3. End Flanges: BS EN 1092-2:1997
  4. Inspection & Test: BS EN 12266

Description

The H41H-16 Flanged Lift Check Valve is a robust non-return valve designed to allow fluid flow in one direction while automatically preventing backflow. Utilizing a spring-guided vertical disc mechanism, it offers faster and more controlled closure than swing check valves, making it essential for protecting pumps and pipelines from water hammer in horizontal installations.
Technical Specifications:
  • Nominal Diameter (DN): DN15 – DN200
  • Nominal Pressure (PN): 1.6 MPa (PN16)
  • Test Pressure (Shell/Strength): 2.4 MPa
  • Test Pressure (Seal): 1.8 MPa
  • Applicable Medium: Water, Steam, Oil
  • Suitable Temperature: ≤ 200°C

Key Product Features:
  1. Spring-Assisted Rapid Closure: The guided vertical disc and spring mechanism ensure quick, controlled shut-off, effectively minimizing water hammer effects.
  2. Durable Hybrid Construction: Features a robust GG25 cast iron body paired with a high-strength GGG40 ductile iron bonnet for maximum structural integrity.
  3. Corrosion-Resistant Trim: Equipped with a 2Cr13 disc and 304 stainless steel seat ring to ensure long-lasting, leak-tight sealing performance.
  4. Horizontal Pipeline Optimization: Specifically designed for vertical disc movement, making it the ideal and most reliable check valve for horizontal piping systems.
  5. Rigorous Testing: Manufactured and tested to strict EN and BS standards (including 2.4 MPa shell and 1.8 MPa seal tests) for guaranteed safety and reliability.
Applications:
Ideal for Municipal Water Distribution, Steam Distribution Networks, Oil Pipelines, and General Industrial Fluid Systems. Specifically suited for horizontal pipelines where preventing reverse flow and mitigating water hammer effects are critical to system safety and longevity.
