WebIf you are using a ‘standard integral’ orifice plate with an upstream inlet side beta of .4, straight run requirements can range up to 20 straight pipe diameters and 10 straight pipe diameters downstream. However, if you are using a conditioning orifice plate with a .4 beta, straight run requirements range from 2-6 straight pipe diameters. WebThe fail-safe mode of a pneumatic/spring valve is a function of both the actuator’s action and the valve body’s action. For sliding-stem valves, a direct-acting actuator pushes down on the stem with increasing pressure while a reverse-acting actuator pulls up on the stem with increasing pressure. Sliding-stem valve bodies are classified as ...
WebOne common misconception about pressure regulators is that they only control pressure immediately upstream or downstream of the valve. However, most pilot-operated regulators and some self-operated regulators operate using an external control or sensing line.This line can be used to control pressure at a remote location in the process pipeline, and … Web• Reliefs valves require a buildup over set pressure to fully open the valve. This build up should be considered when determining the correct relief valve for the application. Speed of Response • Speed of response, in order: • Direct-operated (a.k.a. self-operated) • Two-path pilot-operated • Unloading pilot-operated • Control valve
WebFurthermore, the total unrecovered head loss rarely exceeds 10% of measured d/p (Figure 1). The initial cost of venturi tubes is high, so they are primarily used on larger flows or on more difficult or demanding flow applications. Venturis are insensitive to velocity profile effects and therefore require less straight pipe run than an orifice.

If the PID output changes 5%, the process should respond in a similar fashion regardless of where the output is. (In other words 15% to 20% or 85% to 90% should ideally generate the same process response.)
