Eccentric Butterfly Valve (Model: BV132)
Introduction
The Eccentric Butterfly Valve, model BV132, is engineered for efficient fluid control with lower operating torque. Its soft seat design and precision machined disc ensure reliable, low-leakage operation in water systems.
Working Principle
An eccentric butterfly valve differs from a concentric type by offsetting the stem from the disc centerline. This offset design reduces friction during operation and enhances sealing performance, especially under high-flow conditions.
