These conditions can cause one or more of the heart valves to leak blood backward into the heart chambers or fail to open fully. This makes your heart work harder and lessens its ability to pump blood. Although valve problems can potentially be severe and life-threatening, most valve conditions are also highly treatable.
Regulating valve
Our mission is to be a relentless force for a world of longer, healthier lives. As we move into the second century of our work, we are advancing health and hope for everyone, everywhere.
Our regulating valves are used for adjusting or monitoring flow volumes and flow directions. Specially designed for use in a broad range of metering, blending, weighing and filling system applications, they are the ideal solutions for precision control of flow rate or pressure.

Many heart valve problems are first identified by the presence of a murmur, or sound that can be heard by listening to the heartbeat with a stethoscope. A murmur may sound like a “whooshing” noise as blood flows from one chamber to the next, or it may sound like an extra click when a valve allows back flow. Some murmurs are harmless. Others can indicate an underlying problem with the valve. If a murmur is detected, here are some possible causes.
