Check valve selection guide

Valve Selection Guide. An applications guide for selecting valves. With so many types and options available, choosing the right control valve can seem daunting. Selection can be simplified by considering the process fluid, the service requirements, and how the various valves function. Check Valve. Service. Valve Encyclopedia. Selection Guide. For valves containing solid particulate media, it is required that the flow passage component have to be made of wear-resistant material, and if necessary, the shaft seal should be flushed with a cleaning liquid. Valve Selection Guide - Valves isolate (shut-off), switch, and control the flow of fluids in a piping system. These valves can be operated manually with levers, wrenches, and gear operators or remotely with electric, pneumatic, electro-pneumatic, and electro-hydraulic powered actuators What is a check valve? Check valves are generally installed in pipelines to prevent backflow. In order to be able to choose the right check valve for your application there are a number of selection criteria you should consider. First of all, there is not one type of check valve being the best choice for Valve selection can be quite tricky, but it must not be. Following a simple check-list ensuring that during the selection process all the important key-points are considered is a good step in the right direction. If you are missing some knowledge somewhere, let's say "material resistance" speak to your Valve Selection Guide. ?The above information is for reference only.

Valve type selection should take account of : 1. Required function. 2. Service conditions. This design can cope well with dirty service given appropriate material selection and versions suitable for high General Check valves permit flow in one direction and prevent flow in the reverse direction.

Neither Emerson, Emerson Automation Solutions, nor any of their affiliated entities assumes responsibility for the selection, use or maintenance of any product. It's because check valves are only as good as their application. Oftentimes the problems with a check valve are not related to the valve itself, but Reverse flow is another common check valve problem and can be extremely costly, especially when it occurs at the discharge of a pump, causing the pump No single check valve is all serving. For example, the Lift Check Poppet (Center Guided) would be excellent for clean fluid, but a poor selection for waste water because of the obstructive flow passages. Consider all aspects of your pumping application and refer to the comparison feature chart page 12 Red Valve Company, Inc.l-color, eight-page Check Valve Selection Guide highlights the complete product line of inline check valves and features the Series 39 Inline Slurry Check Valve. The guide has product descriptions, features and benefits, full color product photos Check valves are designed to pass flow in one direction with minimum resistance and to prevent reverse or back flow with minimal leakage. Table 1 summarizes preliminary application guidelines for selection of a suitable type of check valve. The user must evaluate specific application features to Check valves are designed to pass flow in one direction with minimum resistance and to prevent reverse or back flow with minimal leakage. Table 1 summarizes preliminary application guidelines for selection of a suitable type of check valve. The user must evaluate specific application features to Center-guided check valves. Straightening vanes. reduce turbulence in incoming ow, minimizing vibrations that could result in premature Head loss can be an important factor in check valve selection because energy loss in a pipeline can increase expenses signicantly over time in for selecting manual valves, check valves, pressure relief valves, and rupture discs. Valves are the components in a fluid flow or pressure system that regulate either the flow or the pressure Valve Selection Handbook, Fifth Edition: Engineering Fundamentals for Selecting the Right Valve Design
