TISSIN TS600L Pneumatic Valve Positioner 4-20mA IP66 Oil Gas Chemical Power Water Industrial Actuator
Product Overview
The TISSIN TS600L is a linear electro-pneumatic valve positioner developed by TISSIN, a professional Korean manufacturer of valve control accessories. It converts standard 4-20mA DC control signals from DCS or control panels into proportional pneumatic pressure to precisely regulate linear valve stroke within 10-150mm.
Featuring modular die-cast aluminum housing with IP66 protection, it supports single and double-acting pneumatic actuators, with multiple explosion-proof certifications for hazardous industrial sites. This positioner delivers ultra-high positioning accuracy, low air consumption, and easy on-site calibration, making it a stable core component for industrial fluid control systems.
Core Features
- High precision control: Linearity ±1.0% F.S., repeatability ±0.5% F.S., minimal hysteresis for steady valve regulation
- Multiple temperature options: Standard (-20 to 70°C), low-temp (-40 to 70°C), high-temp (-20 to 120°C) models available
- Complete explosion-proof certificates: Non-explosion, Ex dmb IIB/IIC T5/T6, Ex ia IIC T5/T6 for dangerous areas
- IP66 heavy-duty housing: Die-cast aluminum shell resists dust, water jet, and industrial vibration
- Built-in A/M bypass switch: Convenient auto/manual mode switching for maintenance without system shutdown
- Detachable air port module: Supports quick conversion between PT and NPT threads on site
- Low energy loss: Air consumption less than 2.5LPM under 0.14MPa supply pressure
- Simple zero and span adjustment, compatible with split-range control schemes
- Optional accessories: Position feedback transmitter, mechanical/proximity limit switches
- Anti-resonance design: No vibration resonance within 5-200Hz working frequency range
