Direct acting relief valve symbol

WebThis type of sequence valve is a spool-type valve with a spring force that holds the spool closed. So if the inlet pressure exceeds the setting of the spring, then the spool would shift and thus it would direct the flow to the second function. This type of sequence valves is well suited for low pressure and constant flow. WebDirect-acting valves are used to prevent over pressure, and pilot-operated valves are used to regulate pressure. If you are unsure, use a direct-acting valve. Sun's direct acting valves are very fast, dirt tolerant, stable, and robust. Sun's pilot-operated valves are moderately fast, they have a low pressure rise vs. flow curve, and they are ...
