Choosing the Right Fasteners

The best fasteners for valves depend on the specific requirements of each application and the base material of the valve. This includes environmental conditions such as working with chemical process equipment or valves that endure long-term operation.

Look for the type of strength required and choose the correct corrosion resistance, as fasteners receive environmental stress. A few options to consider to prevent several forms of stress corrosion cracking include:

  • Stainless steel fasteners for valves: Stainless steel fasteners are ideal for valve applications where exposure to moisture, chemicals or harsh environments is a concern. If you anticipate chloride-induced stress corrosion cracking as a potential issue, conducting a thorough analysis of the operating conditions is imperative. This is crucial in industries with exposure to chemicals and chlorides, such as coastal plants.
  • Alloy steel fasteners: There is usually a protective zinc or cadmium coat on alloy steel fasteners to reduce general corrosion, which makes them suitable for high-temperature and high-pressure environments. This fastener is ideal for marine environments.
  • Inconel® fasteners: Inconel fasteners are for valves operating in extreme temperatures such as aerospace applications, petrochemical processing plants and high-temperature steam systems.
  • Titanium fasteners: These fasteners offer exceptional strength-to-weight ratio and biocompatibility. They find applications in aerospace, marine, racing vehicles and medical industries.
  • Monel® fasteners: Monel is a nickel-copper alloy known for its resistance to corrosion by acid, alkalis and seawater. This is why they are often used in valves for marine, chemical processing and oil and gas applications.

Valve Types

Behind every smoothly operating valve lies a network of fasteners designed to withstand conditions and ensure optimal performance. There are many variations of valves, each designed to fulfill specific functions. Here are some common types:

  • Ball valves: These are characterized by a spherical closure unit, the ball, that controls flow through a port. Ball valves offer quick on-off operation and tight sealing capabilities, which are ideal for plumbing, oil and gas.
  • Gate valves: Gate valves feature a flat or wedge-shaped gate that controls flow by moving perpendicular to the flow direction. Known for their low-pressure drop and tight sealing, gate valves get used in applications requiring a straight-line flow with minimum restrictions.
  • Butterfly valves: These valves employ a disc mounted on a rotating shaft to regulate flow. Butterfly valves are popular in HVAC systems, plants that treat water and industrial processes due to their compact design and fast operation.
  • Check valves: Check valves allow fluid to flow in only one direction as this prevents backflow. They come in various designs, including swing, lift and diaphragm check valves and get used in pipelines, pumps and pneumatic systems.
  • Globe valves: Globe valves feature a movable disk or plug that controls flow by moving in and out of the valve seat. They are mostly used in flow control applications such as steam systems and process industries.
