Rack and Pinion
HP Series – Pneumatic Actuators
Specification
The V-Flow HP series of rack and pinion pneumatic actuators are specifically designed to provide a wide range of torque outputs to suit quarter turn ball, butterfly, plug valves and dampers for a complete valve automated solution.
Manufactured to high standards using extruded aluminium bodies with a hard anodised coating, the HP series provide a reliable service at competitive prices.
The HP series of Pneumatic Actuators are available in Double Acting (e.g. HP50) and Spring Return (e.g. HP50S) configurations.
| Operating Pressure | 2.5 to 8 Bar |
| Operating Temperature | -20°C to +80°C -35°C to +80°C or -20°C to +150°C on request |
| Certification | SIL2, ATEX, PED, CE, RINA (Marine) |
HP series Actuators feature a VDI-VDE 3845 interface enabling the use of a Namur Solenoid Valve.
For potentially explosive environments, an ATEX explosion proof or intrinsically safe Solenoid Valve can be provided.
Standard Specification:
| Inlet Port | 1/4″ BSP |
| Exhaust Ports | 1/8″ BSP |
| Certification | IP65, SIL4 |
For open and closed position feedback, a switch box can be fitted to the VDI/VDE 3845 interface on top of the unit.
A range of switch boxes can be provided from options with 2x SPDT Switches or Wire Proximity Sensors to IP68 and ATEX explosion proof switch boxes.
Specification
| Enclosure | IP67 Polyester Powder Coated Die Cast Aluminium (IP68 option available) |
| Cable Entries | 2 x M20 (other options available for other switch boxes) |
| Switch Options | 2 x SPDT, 2×2 or 2×3 wire proximity sensors |
Accurate valve position using the HP series Pneumatic Actuators can be achieved using Pneumatic or Electro-Pneumatic positioners which can be fitted to the VDI/VDE 3845 NAMUR interface on the top of the unit.
The positioning system features an IP66 Die Cast Aluminium Alloy enclosure with a corrosion resistant coating and options for ATEX Eexd or Eexia housings.
There are options for a low-profile visual indicator or a dome beacon indicator.
The positioners have a standard ambient temperature of -20°C to +70°C with option of up to +120°C.
Electro-Pneumatic positioners have options for 2x SPDT limit switches and 4-20mA Position Transmitter (output signal).
