Control Valve Sizing and Selection Software
A valve sizing program for control valve manufacturers, customised to your requirements.
We will brand our control valve sizing and selection software to your company, put your products into the menus, and put the technical details of your valves and actuators into the calculations. The program will then work for you to help your employees and agents rapidly produce accurate quotations with detailed specification sheets and prices, respond quickly to enquiries, and impress your customers.
Developed and refined for many years by Millstream Software our valve sizing program is designed specifically for control valve manufacturers to size and select their own range of control valves and actuators, and efficiently produce accurate quotations. We will modify the program to meet your requirements, for example by creating specification sheets in your preferred format or by adding your own trim calculations. The program is in live use at several prestigious valve manufacturing companies, and hundreds of detailed improvements have been made to the program in response to their feedback. Millstream Software will be continuing this process of incremental improvements to maximise your employee efficiency and to support your new business and engineering requirements.

Valve Sizing and Selection
Dec 05 2011 03:20 PM | Chris Haslego in Fluid Flow Sizing flow valves is a science with many rules of thumb that few people agree on. In this article I'll try to define a more standard procedure for sizing a valve as well as helping to select the appropriate type of valve. **Please note that the correlation within this article are for turbulent flow.![Emerson regulator toolkit Emerson regulator toolkit](http://www.downloadcollection.com/graphics/largeimages/psv_2_phase-344300.jpeg)
Step #1: Define the System
The system is pumping water from one tank to another through a piping system with a total pressure drop of 150 psi. The fluid is water at 70 テつーF. Design (maximum) flowrate of 150 gpm, operating flowrate of 110 gpm, and a minimum flowrate of 25 gpm. The pipe diameter is 3 inches. At 70 テつーF, water has a specific gravity of 1.0.
Key Variables: Total pressure drop, design flow, operating flow, minimum flow, pipe diameter, specific gravity
Step #2: Define a maximum allowable pressure drop for the valve
When defining the allowable pressure drop across the valve, you should first investigate the pump. What is its maximum available head? Remember that the system pressure drop is limited by the pump. Essentially the Net Positive Suction Head Available (NPSHA) minus the Net Positive Suction Head Required (NPSHR) is the maximum available pressure drop for the valve to use and this must not be exceeded or another pump will be needed. It's important to remember the trade off, larger pressure drops increase the pumping cost (operating) and smaller pressure drops increase the valve cost because a larger valve is required (capital cost). The usual rule of thumb is that a valve should be designed to use 10-15% of the total pressure drop or 10 psi, whichever is greater. For our system, 10% of the total pressure drop is 15 psi which is what we'll use as our allowable pressure drop when the valve is wide open (the pump is our system is easily capable of the additional pressure drop).
Step #3: Calculate the valve characteristic
For our system:
At this point, some people would be tempted to go to the valve charts or characteristic curves and select a valve. Don't make this mistake, instead, proceed to Step #4!
