LN81 Bellows Valve & ND9000 Positioner: Efficient Fluid Control Solution
Product Introduction
The SUPCON Fluid LN81 series bellows single - seat control valve features a single - seat non - pressure - balanced structure with dual sealing of pressure - resistant stainless - steel bellows and packing, preventing leakage of toxic, flammable media. Its top - guided valve core enables precise flow regulation, ideal for high - leakage - control scenarios.
The Neles ND9000 valve positioner, equipped with a 32 - bit microprocessor and powered by a 4 - 20mA loop, uses non - contact sensors for accurate valve stem positioning. It supports multiple communication protocols like HART and Profibus - PA, and offers powerful self - diagnosis and online monitoring.
Together, the ND9000 overcomes valve stem friction and medium unbalance, driving the LN81 valve for high - precision, rapid - response fluid control.
Features
- LN81 Series Valve: Dual - seal leakage prevention; multiple flow characteristics with up to 100:1 adjustable ratio; DN15 - DN300 diameter and various pressure ratings for diverse applications.
- ND9000 Positioner: Intelligent diagnosis for early fault warning; multi - protocol compatibility; cover - free operation for easy commissioning; IP66 protection and explosion - proof certification for harsh environments.
- Combination Advantages: ±0.1% control accuracy; fast response; stable performance in high - temperature, high - pressure conditions.
Applications
Widely used in chemical, oil & gas, power, water supply, and sewage treatment industries to precisely regulate various fluids, ensuring safe and efficient production.
