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.
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.
The altitude valve will remain open while the tank is not full and will close when the tanks reaches its maximum level.

Thru 1 fnpt automatic flow control.
The uma comes standard with two pressure and temperature test plugs and a universal actuator mounting bracket.
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 limiting valves do not require any additional balancing as do.
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.

A combination automatic flow control valve afcv ball valve and union end.
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.
Thru 1 a combination hot water automatic balancing valve ball valve check valve and double.
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.

Automatic control valves include pressure reducing valves flow control valves back pressure sustaining valves altitude valves and relief valves.
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.
