Process Flow Diagram
A Process Flow Diagram (PFD) is a diagram which shows the relationships between the main components in a system. Process Flow Diagrams are widely used by engineers in chemical and process engineering, they allows to indicate the general flow of plant process streams and equipment, helps to design the petroleum refineries, petrochemical and chemical plants, natural gas processing plants, and many other industrial facilities. ConceptDraw PRO diagramming and vector drawing software extended with powerful tools of Flowcharts Solution from the "What is a Diagram" Area of ConceptDraw Solution Park is effective for drawing: Process Flow Diagram, Flow Process Diagram, Business Process Flow Diagrams.The vector stencils library "Fluid power valves" contains 93 symbols of pre-made hydraulic and pneumatic valves, including directional control valves, flow control valves, pressure control valves, and electrohydraulic and electropneumatic valves.
"Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a "setpoint" to a "process variable" whose value is provided by sensors that monitor changes in such conditions.
The opening or closing of control valves is usually done automatically by electrical, hydraulic or pneumatic actuators. Positioners are used to control the opening or closing of the actuator based on electric, or pneumatic signals.
A control valve consists of three main parts in which each part exist in several types and designs: Valve's actuator, Valve's positioner, Valve's body.

Process Flow Chart
A Process Flow Chart is a type of flowchart which is mostly used in industrial, chemical and process engineering for illustrating high-level processes, major plant processes and not shows minor details. ConceptDraw PRO diagramming and vector drawing software extended with Flowcharts Solution from the "What is a Diagram" Area of ConceptDraw Solution Park is the best way to create Process Flow Chart and other types of flowcharts.A simple hydraulic schematic showing apparatus for testing the strength of a hydraulic hose splice.
Water enters through normally closed solenoid valve (1) and passes through intake flow meter (2) to high pressure pump (4). Intake water pressure is monitored by pressure gauge (3). The hose to be tested connects between pump (4) and normally open solenoid activated drain valve (7). To test the hose, pump drive motor (5) is turned on, the solenoid of drain valve (7) is activated, closing the valve, and the pump is run to pressurize the hose. Test pressure is monitored by gauge (6). When the test is complete or the hose fails, the solenoid of drain valve (7) is deactivated, opening valve and discharging water, depressurizing the system. All components are operated electrically by a remote control circuit so that the operator may perform the test from a protected location, monitoring it with a camera and video monitor.

"HVAC (stands for Heating, Ventilation and Air Conditioning) is a control system that applies regulation to a heating and/ or air conditioning system. Usually a sensing device is used to compare the actual state (e.g., temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g., start the blower).
More complex HVAC systems can interface to Building Automation System (BAS) to allow the building owners to have more control over the heating or cooling units. The building owner can monitor the system and respond to alarms generated by the system from local or remote locations." [HVAC control system. Wikipedia]
