Cast Iron Mute Check Valve

Introduction

The Cast Iron Silent Check Valve (Model BV415) is designed to prevent backflow and minimize water hammer in piping systems. Featuring a streamlined flow-guided disc structure, this valve ensures silent and efficient operation. It is suitable for water systems in various industries, offering flexibility in disc material options including stainless steel, ductile iron, and rubber-coated types.

Working Principle

This silent check valve operates automatically. When fluid flows in the forward direction, the flow-guided disc opens to allow passage. Once the flow stops or reverses, the spring-assisted disc quickly closes to prevent backflow. The guided disc design reduces turbulence and noise, making it ideal for applications where silent performance and protection against water hammer are essential.
