Product Description
Product Details
1. Product Overview
This Smart HART Digital I/P Valve Positioner is a high-precision electro-pneumatic controller designed for linear and rotary pneumatic actuators, compliant with NAMUR installation standards. It supports both single-acting and double-acting actuators, widely matched with industrial control valves for oil, gas, chemical, water treatment and power plant pipelines. Adopting 4-20mA DC signal plus HART communication protocol, it realizes automatic calibration, real-time valve position feedback and partial stroke test to optimize valve control accuracy.
2. Core Advantages
- Dual Signal Compatibility
Standard 4-20mA analog control signal with HART digital communication, support remote parameter debugging, data reading and fault diagnosis without on-site disassembly.
- Wide Actuator Adaptability
NAMUR standard mounting bracket fits all linear (20-100mm stroke) and rotary pneumatic actuators, compatible with single-acting and double-acting types, strong versatility for various ball, gate, globe and butterfly valves.
- Intelligent Self-Calibration Function
One-click auto calibration automatically matches actuator stroke, eliminates manual debugging errors, greatly saves installation and maintenance time for engineers.
- Stable & Durable Structure
Aluminum alloy die-cast housing with IP66 protection grade, internal NBR/PTFE composite sealing components, anti-corrosion and anti-interference, stable operation under normal & medium temperature working conditions.
