Brodie control valves use combinations of pilots and solenoids for multiple applications ranging from back pressure control to differential control.
Brooks back pressure control valve.
1 3 principle of.
Figure 4 in this application the model 750 pressure reducing valve lowers main pipeline pressure to a level that is within the acceptable rating of the metering equipment.
The valves operate on a balanced piston principle spring biased to a closed position.
This adaptable efficient valve utilizes a single body design that can be equipped with a variety of external pilots allowing one valve to serve.
Simpler back pressure control valve an equilibar electronic pressure regulator can directly command the pilot of the equilibar back pressure valve with no pid tuning or sluggish performance.
Piston control valves offering accurate flow control of liquid petroleum products the brodie piston operated control valve ensures a positive seal linear movement and uniform speed of response.
Pressure vacuum products.
Brooks instrument offers control valves and valve replacements for gas and liquid flow applications.
In applications for metering systems or pipelines the bv60 is used to hold a minimum back pressure on the outlet of a meter for more consistent operating conditions.
The heart of the system is a solid state pressure transducer which produces an electrical output proportional to pressure.
In the first post we discussed several gas flow control applications where this is a concern in the second post i described a flow effect called choked flow which occurs when gas flow through an orifice reaches the speed of sound we already know that when gas is flowing through an.
Back pressure control valve acting as a relief valve protects the system if excessive pressure or surge occurs.
Control valves valve replacements.
With a wide range of options and features available the sla5800 series pressure controllers enable you to automate your pressure control and take advantage of the process consistency benefits from using a single platform when combined with our industry leading sla5800 series mass flow controllers and meters.
Accessories software cables filters valves secondary electronics.
The brooks model 5866 pressure controller accurately measures and controls upstream or downstream pressures.
In this series we ve been discussing a gas flow control challenge that users face when backpressure changes.
The electronics use this signal to operate the control valve and to provide an output signal.
