Actuator-Ready 3-Piece Stainless Steel Threaded Ball Valves
An actuator-ready 3-piece stainless ball valve combines a bolted three-piece body with an ISO 5211 mounting pad, suiting both automation and in-line service. Even with the actuator fitted, the centre body can be removed to replace the seats.
According to the manufacturer datasheet it is made for 40 bar maximum pressure in AISI 304 and AISI 316; ball seats are 15 % glass-filled PTFE, O-rings Viton and the spring nut AISI 301. Every valve is factory tested with 10 bar air in open and closed positions.
Main Applications
- Automated process lines needing frequent service
- Automation in food and pharmaceutical plants
- Chemical transfer lines
- Water treatment and filter automation
- Steam and high-temperature water control

Material Options
| Part | AISI 304 | AISI 316 |
|---|---|---|
| Body and cap | AISI 304 | AISI 316 |
| Ball and stem | AISI 304 | AISI 316 |
| Ball seat | R-PTFE (15 %) | R-PTFE (15 %) |
| Packing and body seal | PTFE | PTFE |
| O-ring | Viton | Viton |
| Spring nut | AISI 301 | AISI 301 |
Which material? The spring nut keeps the packing permanently tight, preventing stem leakage on lines where the actuator cycles often. The material table is from the manufacturer parts list; with AISI 316 the wetted parts are 316.
