Description
This double-acting pneumatic actuator is ATEX certified. It is suitable for SIL 2 applications or SIL 3 applications in redundant configuration, making it an ideal choice for safety-critical and hazardous area installations. It is ideal for quarter-turn valves like ball or butterfly valves. The rack-and-pinion mechanism delivers a constant torque of 485.1 Nm at 6 bar (357.81 lb-ft @ 87 psi) with an input pressure range of 3 - 8 bar (43-116 psi). It fits ISO 5211 F10/F12 valves with a 27 mm star connection. The NBR seal allows continuous operation from 0 to 60 °C (32 to 140 °F) and temporary exposure from -20 to 80 °C (-4 to 176 °F). The 35-micron hard anodized aluminum body and polyester coated end covers ensure durability. Features include: mounting holes for Namur Size 1 solenoid valves, a 80 x 30 mm interface for VDI/VDE 3845 limit switch boxes, NPT air ports, stopper bolts to adjust end positions (-10° to +5°), and a clear position indicator. Rated for 500,000+ cycles. Comes with square adapters, bolts, and washers.
Pros:
- ATEX certified for hazardous area and safety-critical use
- Suitable for SIL 2 applications or SIL 3 applications in redundant configuration
- Constant torque of 485.1 Nm at 6 bar over the full 90° stroke
- Direct mounting of Size 1 Namur solenoid valve possible
- Rated for 500,000+ cycles
Cons:
- Uses more air than single-acting actuators
- Requires compressed air and a solenoid valve to control
PR series
The JP Fluid Control PR series consists of rack and pinion pneumatic actuators for quarter-turn valves such as ball and butterfly valves. They are available as double-acting and spring return (fail-safe closing or opening) versions with ISO 5211 valve mounting, NAMUR (VDI/VDE 3845) air supply and top-side interfaces, and BSP G or NPT air ports. The hard anodized aluminum housing and constant torque characteristic make them suitable for a wide range of industrial applications. All actuators are ATEX certified, suitable for SIL 2/SIL 3 applications.
