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 ...
What is Pilot Valve? Working Principle & Types (Complete Guide)
WebA Pressure Reducing Valve can be defined as a self-acting automatic control valve for reducing a higher unregulated inlet pressure to a constant, reduced outlet pressure regardless of the fluctuations in the upstream water pressure. In this article, we will learn about the functions, types, applications, and advantages of pressure-reducing valves. WebDirect acting pressure reducing valves, presented in the Metkoff Ltd. catalog, are capable of delivering flow rates up to 120 liters per minute and withstanding a maximum pressure of 250 Bar. This’s a safe certified equipment, the quality of which meets international standards. Its use will ensure long-term and stable functioning of hydraulic ... le ballon webshop
