Description      Diverter valves are processing valves designed to direct flow from an inlet to one of two or more outlets.  They can also be used for flow control and to converge two lines into one. Diverter valves are primarily used to handle powders, dry solids and slurries, although some types are available that can handle liquid service. They are ideal for applications where the conveying or pumping of materials to multiple vessels or silos is needed.

It is my opinion that the market is oriented in 2 different ways. There is one approach that mainly looks just the cost and another one that believes in innovation. For this last is very important the use of specific materials to designed critical internal valves components to achieve long life of operation and increase by the way valve's performance. According to this: - Research in R&D to use new and specific materials - Research in R&D for new design of internal components to reduce the force or torque (linear or ball valve) normally required to actuate the valve. This results in a compact and efficient design of the valve actuators.

Applications and UseTop

Q:
What are some of the applications you have used diverter valves for?
18 answers
Answers:
As selector valve for fresh or recycled water on recycling systems for cleaning operations. On pump inlets, I used an electric diverter valve to suck water from two wash pits. The valve Actuator was controlled by electronic pit sensors to control the liquid level in the wash pits.
~Bill E, General Management, Brisbane, CA
Mixing of glycol and cooling water for blending; feeding different paint colors to a nozzle for coating; eliminating use of 2 valves and actuators to one unit; elimination of or minimizing deadlegs in piping systems.
~Bill R, Marketing/Sales, East Amherst, NY
Our plant cooling system uses a thermostat controlled diverter valve to maintain a minimum cooling water temperature of 70 degrees during the colder months. This prevents our equipment from condensating.
~Ted P, Senior Maintenance Tech, Troy, MI
There are applications for diverter valves in LC/MS/MS work. Valves are useful for switching between different mobile phases and diverting flow to instrument or waste after separation on HLPC columns.

Q:
Please share with us any “non-standard” applications that a diverter valve has been used for.
3 answers
Answers:
I am currently working on setting up a diverter valve to switch between mobile phases. Mobile phase pumps are typically designed to switch between two mobile phases, but it would be beneficial to expand the mobile phase selections for running multiple assays on one instrument.
~Research & Development, Flagstaff, AZ

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of a diverter valve?
5 answers
Answers:
Ordered a valve that required multiple adapters for the line, then found that the switch was made of a polymer that weakened in the presence of the solvents I wanted to divert.
~Research & Development, Flagstaff, AZ
Customers using a 1/4 turn set-up will have exposure from both ports as it cycles through, where sometimes it is undesirable to have both fluids exposed at the same time.
~Bill R, Marketing/Sales, East Amherst, NY
I had the wrong size and could not get the proper cooling or heating performance as required.
~Craig L., Technical Support, Carson City, NV
The most common error is the mistake in installation about correct valve port connection.

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of a diverter valve?
6 answers
Answers:
Make sure actuation can fit into your piping layout, and not interfere with other equipment. Make sure your feed pressure is higher than the pressure in the port that the flow is directed to.
~Bill R, Marketing/Sales, East Amherst, NY
Make sure of the the thread sizes, check and make sure that the fittings are male or female, read manufacturer's instructions.
~John W, Heating engineer plumber, Cramlington, United Kingdom
Check the specs so the valve is compatible with the pressures and fluids you're working with.
~Research & Development, Flagstaff, AZ
Too big or small will not give you the correct flow, or velocity.
~Craig L., Technical Support, Carson City, NV
Best practices available in literature and in many technical brochures provided by valves manufacturers and HVAC equipment manufacturers are enough. The rest is experience. Useful also in my opinion to share information within the specific blog.
~Massimo Marchese, Technical Support, Fontaneto d'Agogna, Italy
Are you expecting 100 percent diverting? or is 90% enough?
~R B, General Management, Berkeley, Alameda

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using diverter valves?
9 answers
Answers:
Keep in mind your flow rates through the porting areas are significantly reduced, especially with the more ports you have. Electric actuation is much easier to use on valves requiring 180 degree rotation.
~Bill R, Marketing/Sales, East Amherst, NY
Understand the process application the valve will be used in, will the valve ever be used for isolating, or is a constant flow path always required.
~Mike B, Engineer, Boston, MA
Buy well established brand from well established distributor, so that the replacement parts for future service will be readily available.
~R B, General Management, Berkeley, Alameda
Check the specs so the valve is compatible with the pressures and fluids you're working with.
~Research & Development, Flagstaff, AZ
Cheap diverter valve may have small passages, buy full flow valves if possible.
~Bill E, General Management, Brisbane, CA
Select the shut of class depending on the application. Select right material.
~SHARAD S, Marketing/Sales, Vadodara, Gujarat, India
Ask as many questions as you can. All questions are important.
~Ted P, Senior Maintenance Tech, Troy, MI
Shop around, easy to fit and maintain, price,
~John W, Heating engineer plumber, Cramlington, United Kingdom
Get the right size, and the correct actuator.
