Automatic Flow Control Valve Design

Control valve sizing procedures are based on accepted mathematical methods such as those detailed in isa 75 01 01 2007 flow equations for sizing control valves. We offer automatic control valves that are used to ensure uninterrupted water service during emergencies maintain a constant liquid level in tanks automatically reduce a higher upstream water pressure to a constant downstream pressure and for other purposes.

Automatic flow control valve design.

Automatic flow limiting valves do not require any additional balancing as do. These fluctuations in pressure within a given pressure differential control range do not change the flow through the valve therefore the flow is controlled to within 5 of the designed flow. Automatic control valves are used in commercial and industrial applications to control water flow or pressure. Thru 1 a combination hot water automatic balancing valve ball valve check valve and double.

A combination automatic flow control valve afcv ball valve and union end. An actuator will stroke the valve depending on its input and set up allowing the valve to be positioned accurately and allowing control over a variety of requirements.

Our space saving automatic balancing valves for instance are easy and quick to install and can help reduce pump energy consumption by as much as 10 they also help minimise maintenance costs by reducing the time it takes to achieve optimal system balancing as well as ensuring they benefit from tamper proof features that help to optimise flow control for the life of the installation. An altitude valve controls the level of a tank.

These methods can be used to develop accurate valve sizes however during the course of plant design control valves are often sized based on a future maximum design process load. An automatic flow control valve afcv. 1 0 50 gpm 15 00 gpm. 0 33 gpm 8 00 gpm.

The altitude valve will remain open while the tank is not full and will close when the tanks reaches its maximum level. Automatic control valves include pressure reducing valves flow control valves back pressure sustaining valves altitude valves and relief valves. More complex control systems using valves requiring automatic control based on an external input i e regulating flow through a pipe to a changing set point require an actuator. The uma comes standard with two pressure and temperature test plugs and a universal actuator mounting bracket.
