Automatic flow control valve design.

0 33 gpm 8 00 gpm. Nexus manufactures hydronic flow control valves automatic flow control valves manual balancing valves coil piping package and heat pump hose kits. Automatic control valves include pressure reducing valves flow control valves back pressure sustaining valves altitude valves and relief valves. Automatic control valves are used in commercial and industrial applications to control water flow or pressure.

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. 8908 governors row dallas texas 75247 usa. An altitude valve controls the level of a tank. 8908 governors row dallas texas 75247 usa.

The altitude valve will remain open while the tank is not full and will close when the tanks reaches its maximum level. Imi hydronic engineering inc. 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. An automatic flow control valve afcv.

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. For a demonstration of the flow control valve in action click here. 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. 1 0 50 gpm 15 00 gpm.

A combination automatic flow control valve afcv ball valve and union end. 0 50 gpm 15 00 gpm. Thru 1 fnpt automatic flow control. The uma comes standard with two pressure and temperature test plugs and a universal actuator mounting bracket.

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 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.
