EVA UPVC Butterfly Valve ISO 5211 is a high-performance flow control device designed for corrosive environments and automation-ready systems. It features a wafer-style body made from Unplasticized Polyvinyl Chloride (UPVC), known for its chemical resistance and lightweight properties. The valve integrates an ISO 5211 mounting pad, allowing direct installation of electric or pneumatic actuators without additional brackets or couplings.

EVA UPVC butterfly valve compliant with ISO 5211 is a type of valve commonly used for flow control in pipelines, particularly in water and other fluid applications. The ISO 5211 standard specifies the interface for attaching actuators (like pneumatic or electric) to the valve, allowing for automated control. This means the valve can be easily fitted with an actuator from various manufacturers, offering flexibility and ease of maintenance. 

Here's a more detailed breakdown:

UPVC Material:

The valve body and components are made of unplasticized polyvinyl chloride (UPVC), a durable and corrosion-resistant material suitable for many fluid applications. 

Butterfly Valve Design:

It features a rotating disc (the "butterfly") within the valve body that controls flow by opening and closing. 

ISO 5211 Compliance:

This standard defines the dimensions and interface for attaching part-turn actuators (like those used with butterfly valves). Mounting Interface: ISO 5211 (e.g., F05, F07, F11) – standardized flange for actuator compatibility

Actuator Compatibility:

The ISO 5211 standard ensures that actuators from different manufacturers can be easily mounted to the valve, simplifying installation andmaintenance.

Applications:

UPVC butterfly valves are commonly used in water supply, irrigation, and other systems where corrosion resistance and ease of control are important.
