Bellows Valve / Bellows Seal Valve
Bellows valves or bellows seal valves are used to prevent leakage in piping systems. Bellows valves are important because they're often used in piping systems that transport potentially harmful liquids and gases. When designed and used properly, they reduce the risk of leakage and subsequent exposure chemicals and potentially harmful substances, allowing for improved safety of assemblies. Bellows valves are often used in sealing applications for aerospace, biotechnology, chemical processing, nuclear power, petroleum, pharmaceutical, and semiconductor.
MW Components manufacturers standard and custom metal bellows and metal bellows assemblies fit for a variety of applications and industries and will work with you to your designated specifications or in combination with your team to determine the right specifications for your application.

Bellows Valve Manufacturing
MW Components produces bellows valve assemblies using Hydroforming Technology. We work with a variety of materials and can produce multiple sizes, wall thicknesses, and added customizations. Below are typical ranges for our hydroformed metal bellows and assemblies.
Production Capabilities for Hydroformed Components:
- Size ranges from 1/4" I.D. to 48" I.D.
- Wall thickness ranges from 0.002" single-ply to 0.056" multi-ply
- Precision CNC machining within a few thousand of an inch
- Material options include stainless steel (300 series), Inconel®, Hastelloy®, titanium, copper, Monel™, brass, and phosphorus bronze
- DFAR-compliant materials available
For information about metal bellows outside of these ranges produced using other manufacturing processes including electrodeposited technology and edge-welded technology and to determine which may be right for your application, review this metal bellows comparison guide.
Advantages of Bellows Valves
Bellows valves have a number of advantages over other options, including:
- Precise temperature-dependent mechanical actuation without the need for programming or electricity
- Mechanically modulate heating and cooling systems
- Operate through billions of repeatable cycles without requiring recalibration
Optional Customizations for Bellows Valve
Our bellows valve assemblies are produced using precision hydroforming technology, which allows for multiple customizations. As an expert bellows manufacturer, we also offer a variety of non-standard manufacturing processes and customizations including the below.
- Multiple flange sizes in one assembly
- Customization to standard bellows valve available (holes, slots, etc.)
- Through-hole (clearance hole) and tapped-hole flange styles
- Custom end-configurations
