Discover the National Standard Swing Check Valve (H44H model), an essential cornerstone in the world of industrial piping systems. Meticulously engineered, this valve is the guardian against backflow, ensuring seamless and uninterrupted performance across a myriad of applications.
Comprehensive Product Overview and Detailed Technical Specifications
The H44H Swing Check Valve is masterfully crafted to accommodate a wide range of nominal pressures, from PN1.6MPa to 42.0MPa and Class150 to 2500LB. It covers nominal diameters from DN15 to 500mm and PNS1/2 to 20". Designed for resilience, it operates in temperatures from -196ºC to 540ºC, using robust materials like carbon steel and stainless steel. This valve excels in managing mediums such as water, steam, gas, oil, and acidic substances.
Innovative Working Principle and Distinct Structural Features
The H44H Swing Check Valve boasts an advanced internal rocker arm swing structure, where all components are securely enclosed within the valve body, ensuring no external penetration. The strategic use of sealing gaskets and rings at the middle flange eliminates any external leakage, significantly reducing valve leakage risks. The valve disc elegantly pivots around its axis, opening under fluid pressure. When higher pressure is detected on the outlet side than the inlet, the disc automatically seals shut, driven by pressure differentials and gravity, effectively preventing backflow.
Diverse Applications and Unique Advantages
The H44H Swing Check Valve is a versatile solution, extensively employed in water supply, drainage, fire safety, HVAC, and other industrial systems. Its standout features include:
Ideal for a Wide Range of Environments: Perfectly engineered for the petroleum and chemical sectors, as well as thermal power plants, and beyond.
Reduce Water Hammer Pressure: Engineered with a hydraulic-compliant design and a streamlined internal guide body, it ensures minimal pressure loss.
Outstanding Sealing Performance: The sealing surfaces of the valve disc and seat are made from iron-based alloy or Stellite cobalt-based hard alloy, providing excellent resistance to wear, temperature, and corrosion for prolonged durability.
Seamless Installation: Compatible with various piping flange standards and sealing types, designed to fulfill diverse engineering specifications and customer needs.
