Neles NE700 NP700 Valve Positioner Electropneumatic Pneumatic Control

The Neles NE700 (electropneumatic) and NP700 (pneumatic) valve positioners are precision instruments designed for control valve automation in harsh industrial environments. Engineered for reliability, these positioners deliver accurate performance across rotary or linear valves, with rugged construction ensuring resistance to vibration and extreme temperatures. Paired with China's leading pneumatic diaphragm control valve supply, they offer seamless integration for throttling applications in oil & gas, chemical processing, and power generation.

• Smart Control - 4-20mA input signal with HART compatibility (optional). Low air consumption via pulse-width modulation (PWM).
• Durability - IP54-rated aluminum enclosure with stainless steel internals. Operates in -25°C to 120°C environments.
• Ease of Use - Quick calibration with zero/span adjustments. Direct/reverse action toggle via feedback cam.

• Precision Regulation - 0.2-1 bar input pressure for proportional pneumatic output. Force-balanced diaphragm piston for stable operation.
• Adaptability - Compatible with diaphragm or cylinder actuators. Multiple pilot valve sizes for optimized response time.
• Vibration Resistance - Compact design with rigid mounting to withstand harsh conditions.

• Industries - Oil & gas, petrochemicals, power plants, pharmaceuticals.
• Processes - Flow/pressure control, throttling, and isolation in critical systems.
• Environments - Hazardous areas (ATEX/CE certified), extreme temperatures, high-vibration settings.
