Product Description

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.​
