Product Overview

The Axial Non-Slam Check Valve is an advanced flow control device engineered for efficient and reliable operation in a wide range of industrial applications. Designed to prevent reverse flow while minimizing pressure surges, this valve ensures smooth and uninterrupted pipeline operation.

Product Features

  • Non-Slam Operation: The axial design eliminates water hammer and reduces pressure surges by allowing a controlled closure of the valve. This ensures pipeline integrity and minimizes equipment wear and tear.
  • Axial Flow Design: The streamlined flow path reduces turbulence and pressure drops, making it ideal for high-efficiency systems and extending the lifespan of the valve and associated equipment.
  • Compact and Robust Construction: The valve’s compact body design and high-quality materials provide durability, even in harsh environments such as high-pressure or high-temperature systems.
  • Low Maintenance: With fewer moving parts, the valve requires minimal maintenance, reducing downtime and operating costs over its lifecycle.
  • Versatile End Connections: Available in standard RF (Raised Face) and optional RTJ (Ring Type Joint) end connections to suit a variety of industrial pipeline configurations.
  • Material Options: Manufactured with a range of materials, including Buna, EPDM, Viton, TFE, and Zelon for seals and gaskets, ensuring compatibility with various media and operating conditions.
