The National Standard Swing Check Valve (H44H model) stands as a pivotal component in the realm of industrial piping systems. This valve is expertly designed to avert the backflow of medium, ensuring smooth, uninterrupted operation across diverse applications.
Comprehensive Product Summary and Technical Specifications
The H44H Swing Check Valve is engineered for a vast array of nominal pressures, ranging from PN1.6MPa to 42.0MPa and Class150 to 2500LB. Its nominal diameter spans DN15 to 500mm, and PNS1/2 to 20". Designed to operate within a temperature range of -196ºC to 540ºC, this valve can be crafted from materials such as carbon steel and stainless steel. It is adept at handling mediums including water, steam, gas, oil, and acidic substances.
Innovative Working Principle and Unique Structural Attributes
The H44H Swing Check Valve is characterized by its internal rocker arm swing structure. Ingeniously, all operational components are housed within the valve body, eliminating external penetration. The deployment of sealing gaskets and rings in the middle flange ensures no external leakage, thus curtailing valve leakage risks. The valve disc pivots around its axis, opening under fluid pressure. Upon detecting a higher pressure on the outlet side than the inlet, the disc auto-closes, courtesy of pressure differentials and gravitational forces, preventing unwanted backflow.
Diverse Application Fields and Distinct Advantages
The H44H Swing Check Valve is a versatile solution, finding extensive applications in water supply, drainage, fire safety, HVAC, and industrial systems. Its distinctive features include:
Optimal for a Broad Spectrum of Environments: Perfectly suited for the petroleum and chemical industries, as well as thermal power plants, among other settings.
Mitigate Water Hammer Pressure: Designed with a hydraulic-compliant contour and a streamlined internal guide body, ensuring minimal pressure loss.
Exceptional Sealing Performance: The sealing surfaces of the valve disc and seat are crafted from iron-based alloy or Stellite cobalt-based hard alloy, offering superior wear, temperature, and corrosion resistance for an extended lifespan.
Effortless Installation: Compatible with a variety of piping flange standards and sealing types, tailored to meet diverse engineering specifications and customer demands.
