U Style flanged butterfly valve

Description

The flange butterfly valve serves as a versatile and reliable cost-effective solution for various industrial applications through its superior flow regulation and throttling capabilities.

Main Features

ISO 5211 Top Flange: The product enables direct mounting of actuators which creates a secure tight connection for efficient valve operation.
Stem Anti-Blowout Design: The safety feature stops the stem from exiting the valve during operation thus protecting workplace safety and equipment integrity.
Two-piece Construction: The design simplification and improved sealing capabilities of this valve minimize leakage and maintenance needs.
Rotatable Disc: The device delivers precise flow control which allows users to adjust flow rates with ease.
Full-Ported Design: The system operates with continuous fluid flow at low pressure drop which enhances the overall system efficiency.
