A throttling valve is not a control valve in the sense that it does not control downstream pressure. For most blowdown and many other applications, throttling valves are a smart option to consider.

In three-port valves, or shuttle valves, internal ridges guide the ball between ports. Restrictive flow regulators work like an automatic variable orifice to control flow by throttling or restricting.

Whether it’s a control valve or an on/off valve, make sure the process is addressed [by the valve in] the way it's intended in the design.” The Fisher V250 control valve is a heavy-duty, flangeless ...

Typically, the throttling is performed with a ball valve (although the British prefer a globe valve) and the measuring is accomplished with either a venturi or an orifice plate. The two components are ...
