Ball valves and actuators
Ball valves with electric actuator
This category covers ball valves fitted with an electric actuator: threaded valves in stainless steel and nickel-plated brass, 3-way ball valves with L-bore or T-bore, flanged and compact flanged ball valves, and PVC-U ball valves with solvent socket or female thread. Connections range from G 1/4 to G 4 and Rp 1/2 to Rp 2, through butt-weld ends from 13.5 to 114.3 mm, up to flanges DN 15 to DN 150 in PN 16 and PN 40. Most actuators run on 24-240 V AC/DC and come as standard version, with battery safety return or with a positioning system. The Köly PVC-U range has its own neighbouring category.
Narrow the range by function, supply voltage, thread or nominal size.

How to choose Ball valves with electric actuator
What matters when choosing: properties, comparison and typical applications.
Selection criteria
| Criterion | Options | What to check |
|---|---|---|
| Valve type | Threaded ball valve, 3-way ball valve, flanged ball valve, compact flanged ball valve, PVC-U ball valve, high-pressure ball valve | Flanged and compact flanged valves differ in face-to-face length. Check the installation dimension when replacing a valve. |
| Connection | G 1/4 to G 4, DIN/EN flange DN 15 to DN 150, solvent socket or female thread DN 15 to DN 100, Rp 1/2 to Rp 2, butt-weld ends 13.5 to 114.3 mm | For weld ends the pipe outside diameter is decisive, for flanges also the pressure rating PN 16 or PN 40. |
| Body material | Stainless steel, nickel-plated brass, PVC-U, stainless steel 1.4571, stainless steel 1.4408, galvanised steel | The body material has to suit the medium. Check chemical resistance against the data sheet. |
| Supply voltage | 24-240 V AC/DC, 12-24 V AC/DC, 85-240 V AC/DC, 24 V AC/DC | Match the voltage to the supply in the control cabinet. Actuators rated 24-240 V AC/DC accept both AC and DC. |
| Actuator version | Standard, battery safety return, positioning system 0-10 V / 4-20 mA, 140 s actuating time, 9 s actuating time | Decide whether the valve only needs to open and close, move to a defined position on power failure or hold intermediate positions. |
| Seal | EPDM, FKM | For PVC-U ball valves, choose the seal according to medium and temperature. |
| Media temperature | -20 to +100 °C, -30 to +100 °C, -20 to +120 °C, -20 to +150 °C, -20 to +160 °C | The permitted range applies per item and depends on body and seal. |
