SwiftChange™ 2-way Diaphragm Valve

Change diaphragms fast, without removing the topworks.

The SwiftChange™ 2-way diaphragm valve offers everything you want in an aseptic diaphragm valve, with a twist—change diaphragms in under a minute. No loose parts, no complex procedures, no heavy lifting.

SwiftChange™ TWS Series

How It Works

The procedures for removing and installing diaphragms in a SwiftChange™ TWS Series valve consist of a few simple steps.
Removing the topworks is not one of them.

Removing the diaphragm

Step 1

Loosen the two perimeter seal (PS) bolts enough to allow the swivel plate to rotate.

Step 2

Rotate the swivel plate clockwise as far as it can go. 

Step 3

Use the handwheel or actuator to open the valve,

Step 4

Slide diaphragm out
through access window.

Done

Diaphragm can now be inspected and/or replaced.

Installing the diaphragm

Step 1

Slide diaphragm in
through access window, aligning key in keyway.

Step 2

Use the handwheel or actuator to close the valve..

Step 3

Rotate the swivel plate counterclockwise as far as it can go.

Step 4

Tighten down the two perimeter seal (PS) bolts.

Done

Valve is now in an operational state.

SWIFTCHANGE™ TECHNOLOGY

Brilliantly simple technology that delivers.


1 Valve's goals for its SwiftChange™ technology are to provide robust, flexible solutions that save time and money, and are easy to use. In addition, the technology should be universally adaptable to a wide range of applications across many industries. 

Below are just a few features and benefits that 1 Valve's patent-pending SwiftChange™ technology delivers.

SwiftChange 2-way diaphragm valves are available with manual handwheel or pneumatic actuators.

Frequently asked questions

SwiftChange™ Technology FAQs

Contact us

SwiftChange™ technology is simple to use, but it's unlike anything else out there. That means lots of questions.

Here are a few frequently asked questions and answers.

If you have additional questions or want more in-depth answers, click the button below to contact us.

  • Will SwiftChange™ bonnets and actuators work with existing valve bodies from other vendors?

    We’re currently testing our solution for retrofitting SwiftChange™ topworks to existing valve bodies. It requires no cutting, welding, or changes to process contact surfaces. In many cases you can use existing diaphragms with our adapter key.   

  • Is SwiftChange™ technology patented?

    Yes, 1 Valve’s SwiftChange™ technology is protected by multiple US and international patents and patents-pending. As patents issue, they will be listed on our Patents page.

  • Do I really never need to remove the topworks?

    There is no need to remove the topworks for routine maintenance, such as changing the diaphragm. The handwheel mechanism can usually go many years without any problems. However, should you ever need to service the actuator mechanism, or if you want to upgrade to an automated actuator, the actuator can be removed. 

  • How often should I change diaphragms on a SwiftChange 2-way valve?

    The frequency of diaphragm changes really depends on the process, but it is generally agreed that diaphragms should be changed at least once a year. Because it is so easy to inspect and change diaphragms on valves equipped with SwiftChange™ technology, you may determine that you can change diaphragms more or less frequently.

  • What are your additional questions?

    1. Are there autoclavable options?
    2. Are there cleanroom options with no exposed threads?
    3. Are the actuators sealed?
    4. Can you remove the diaphragm from either side?
    5. Can you orient the actuator to access the diaphragm inline with the valve flow path?
    6. Do SC actuators work with block valves?
    7. How many sc actuators can you fit on a block?
    8. Can multiple SC valves be controlled by a single SC actutor?
    9. Can the process of changing a diaphragm on a SCA equipped valve be automated?
    10. With SCT, can a skid, a suite, or even an entire facility be configured to change diaphragms simultaneously?
    11. Can a manual SCA equipped valve be converted to an automated version?
    12. How do you come up with the claim that a SCA equipped valve can pay for itself in just a few diaphragm changes?
    13. Are there loose parts to manage during a diaphragm change? Only the diaphragm.
    14. Are tools necessary to change a diaphragm. In some cases no. What tools are necessary? Depends on the series. The TWS series requires an allen wrench or screwdriver. The TWC series requires no tools.
    15. Can a SCA work with my existing diaphragms? Can I continue to use my current diaphragms?
    16. Can SCT be licensed? Is the company for sale?
