Frequently Asked Questions
Double-acting or single-acting actuator?
A double-acting actuator uses air to open and air to close, and stays where it is if the air fails. A single-acting (spring-return) actuator uses air in one direction and a spring in the other, so the valve moves to a set position, usually closed, when the air fails.
What sizes do the tri-clamp ends fit?
Sizes are given as tube outside diameter. The clamp ferrule diameter for each size is in the dimension table.
How do I install an actuated ball valve?
Before installation, run a seat leak test and a few open/close cycles without load: the valve must move smoothly with no sticking. Clean the bore, sealing faces and pipe flanges, and tighten the connection bolts evenly. The valve can be installed in any position; leave room for maintenance and manual operation.
What maintenance does the valve need?
Check the seals regularly and replace them when worn. Clean dirt and deposits from the valve without scratching the ball. Lubricate moving parts, and add a little lubricating oil inside the pneumatic cylinder about every 18 months. Always cut off the air and power supply before working on the valve.
What documents ship with the valve?
A product test report with the heat number of the body casting, materials and the pressure test results. We welcome third-party inspection (e.g. SGS or BV), arranged and paid for by the buyer.
What is the lead time?
Standard sizes ship in 15–20 days. Special actuators, voltages or accessories may take longer; we confirm the date with your quote.
Can I get a different body material?
Yes. CF8 and CF8M are our standard; the body material can be changed to suit your media. Tell us the media and temperature and we confirm the material with your quote.
