Selection of the right valve in industrial applications where corrosive environments are a concern is crucial to ensuring operational efficiency and safety. One of the top choices in these scenarios is the rubberlined butterfly valves, specifically the Rubberlined EVFS series from Wouter Witzel. 

The rubber-lined valve type has a thick polymer lining on both the disc and the body. The lining has outstanding anti-corrosive properties and isolates the body from the medium completely.

Designed with robust features and advanced specifications, these valves offer unparalleled performance in handling corrosive fluids. Let's dive into the key benefits and specifications that make these valves a preferred choice for industries dealing with harsh environments.

 

Why Choose Rubberlined Butterfly Valves?

 

Rubberlined butterfly valves are engineered to provide optimal performance in corrosive and abrasive conditions. Their unique design and material construction prevent damage and extend the life of the valve. Hence, making them a reliable and cost-effective option for industries such as chemical processing, wastewater treatment, and mining.

 

Key Benefits of Rubberlined Butterfly Valves

 

Corrosion Resistance: The rubber lining, bonded through vulcanization, acts as a protective layer against corrosive substances. It ensures the valve’s longevity even in the harshest environments.

Enhanced Durability: The concentric design with a bonded rubber lining provides a robust sealing mechanism that reduces wear and tear. As a result, it minimises maintenance and replacement costs.

Cost-Efficiency: Compared to other butterfly valve types, rubberlined butterfly valves offer an economical solution. Especially, for applications requiring frequent handling of aggressive media.

Versatile Application: These valves are suitable for a wide range of applications due to their adaptability to different types of corrosive fluids.

 

Understanding the Rubberlined EVFS Series

 

The Rubberlined EVFS series butterfly valves from Wouter Witzel are specifically designed for high performance in challenging environments. Their technical specifications and construction features make them ideal for demanding applications.

  1. Construction

The EVFS valves are concentric butterfly valves with a bonded vulcanised rubber lining. This construction ensures a tight seal and effective corrosion resistance, critical for maintaining the integrity of the valve over time.

  1. Short Pattern Double Flange Design

The short pattern double flange face-to-face configuration makes installation easier. While the double flanged body type enhances stability and reliability, especially in high-pressure applications.

  1. Disc Edge Protection

The unique design reduces disc-to-pipe protrusion, providing edge protection to the disc. This feature not only enhances the durability of the disc but also ensures smooth operation without interference with the pipe walls.

  1. End-of-Line Duty

The valves are capable of handling end-of-line duty by through bolting to pipe flanges. This is beneficial for operations where a secure shut-off is required without additional support downstream.

  1. Design Pressure and Sealing

With a design pressure of 16 bar (232 psi) and a reliable rubber seat sealing, the EVFS valves can handle high-pressure applications effectively. Hence, preventing leaks and ensuring safety.
