CVT Technical Support - Selecting The Right Valve

Apr 05, 2012

One of the key elements in selecting the right check or relief valve is Flow Capacity. This essential element is often not given enough consideration, especially when a replacement valve is being specified. Because of this, a common problem that arises is the valve will be over-sized for the application. When the flow is insufficient to keep the valve open, it will "chatter" and may result in...
