SMC Type Valve Positioner

IP8000/8100 Electro Pneumatic Valve Positioner

IP8000 / IP8100 pair — lever and rotary in one specification

Buyers who standardise on the SMC pattern usually order both members of the family: IP8000 lever type for linear valves and IP8100 rotary type for quarter-turn valves, sharing one spare-parts list, one air-port thread choice and one data sheet.

One specification covering lever (IP8000) and rotary (IP8100) builds
Input 4–20 mA DC, input resistance 235±15 Ω
Supply air 0.14–0.7 MPa on the electro-pneumatic builds
Air ports Rc 1/4, NPT 1/4 or G 1/4; electrical G 1/2, M20×1.5 or NPT 1/2
Aluminium diecast body with denatured epoxy baking finish

Typical duty: Plants and OEMs keeping one positioner family across both linear and quarter-turn valves.

Technical background

The IP8000 E/P positioner is more compact than the IP6000 with improved visibility of the pressure indicator. Other features include an improved enclosure protection IP65, interchangeable mounting, excellent shock and vibration performance, and a 1/2 split range available by simple span adjustment.

Output current (4-20mADC) realizes remote position detecting (rotary type) Vibration resistance: No resonances 5 to 200Hz Dust resistance: Conforms to JIS F8007 IP65 Pressure gauge O.D. 43 Accessories include: Output restriction w/pilot valve, fork lever joint, compensation spring, w/external scale plate IP8100 , Electro-Pneumatic Positioner, Rotary type. Output current (4-20mADC) realizes remote position detection.

External scale plate is installed for easy reading of valve position. The pressure gauge diameter is increased to large size for easy reading. Interchangeable with IP6#00 series .

Questions buyers ask

Can I mix threads across an order?

Yes — air and electrical connection threads are model-selection options, so a single order can carry more than one thread type.

What is the weight difference?

2.4 kg without terminal box, 2.6 kg with it, for the electro-pneumatic builds.
