Stainless steel ball valves with actuator pneumatic actuators
Pneumatic actuator
Alphair
The springs of the single-acting actuators ensure a safety drive position should the control air suddenly fail.
| Functional principle | opening | closing |
|---|---|---|
| single-action | air | spring |
| double-action | air | air |
The pressure cartridges with springs that are made of high-quality spring steel ensure a high degree of corrosion protection and a long durability.
An control air pressure of 6 bar is required so that the ball valve and the springs can be moved in this case.
- Adjustment screws for adjusting the swivel angles
- Air interface conform with VDI / VDE 3845 (Namur)
- valve interface acc. ISO 5211 / DIN 3337
- Multifunctional interface for an optical position indicator, a limit switch box, or a positioning device
ATEX
EX-protected range acc. ATEX-94/3-CE
II 2GD c Tmax = 95° C
SIL3 - Security level 3.
Air supply
Dry or lubricated and filtered compressed air
Activating pressure
min. 6 bar control air / max. 8 bar continuous pressure
Temperature range
NBR o rings ensure a faultless function at standard temperatures.
| Standard | Low-Temp. | High-Temp. |
|---|---|---|
| -20 to 80° C | -40 to 80° C | -20 to 150° C |
O rings made of viton are recommended for high temperatures and silicone for low temperatures.
Switching frequency / Durability
The actuator is lubricated in the works.
The works guarantee 1,000,000 switching cycles for the standard models.
Max. 100,000 switching cycles are guarantee for the springs ex works.
