To grind the valves and head we need some grinding paste. The paste is simple enough – powdered carborundum suspended in a grease base. Buy a small tub and it'll last you a lifetime. The …

System Operation. The PLC activates the pump, generating system pressure and flow. It needs to ensure the main valve is open to prevent the pump from deadheading against the valve. The SCADA system will check the valve position and open it prior to starting the pump. The flow meters transmit the flow rate to the PLC.

Productivity and accuracy are the goals to strive towards when performing valve grinding operations. Here are some "Pro Tips" to help you get the most from your engine valve …

Globe valves are also capable of precise throttling. This makes them ideal for control applications as they are also well suited to steam application due to the "up-and-over" design which can handle high-pressure drops. Ball-segment valves are ideal for very precise control applications as they give linear control characteristics with high ...

Repelletizing will eliminate this problem; the regrind is melt-filtered to remove non-plastic contamination. Unfortunately, this adds $0.12 to $0.20 per pound. For process stability, perform regular grinder maintenance: sharpen the blades, clean the machine, and make sure the screen is working properly.

There is no cookie-cutter approach to selecting from the many different types of available process valves. Facility owners and their process engineering partners should carefully consider the cleanability, compatibility and maintenance of individual valves within their overall system in order to select the best one for the job. 1. Cleanability

Control valves are power-operated devices used to automatically modify fluid flow or rate pressure in a process system. The terms 'control valve' and 'throttling valve' are often used interchangeably but there is a distinction between the two. A throttling valve is a valve whose closure element has the ability to start and stop flow as well as ...

Main Criteria for Selecting an Industrial Valve. You can choose the right type of valve for the application by using the media type, the materials of construction, the valve characteristics, the pressure/temperature of the media, and the pressure class of the piping system. Keep these criteria in mind when specifying any industrial valve:
