LN8

系列顶导向单座控制阀

产品概述

LN8 series top-guided single-seat control valve is a top-guided, plunger type single-seat control valve。Obtained TUV ISO15848 certification in 2019。It has the characteristics of high control precision, good sealing performance, simple structure and strong versatility。适宜于要求控制精度较高的工况流体控制。可采用波纹管密封型。It has been applied thousands of times in fine chemical, petrochemical, pharmaceutical and other industries。

产品型号

LN81系列单座调节阀

LN81 series is one of the two base products of LN8 series pressure imbalance single-seat structure, top guide plunger spool, floating compression sleeve, self-centering seat structure, modular design。Large flow capacity, high adjustment accuracy, wide adjustable range, can achieve minimal flow control, simple and reliable structure, good sealing performance, easy to maintain on site。It is suitable for occasions where the pressure difference is not large, the leakage of the valve seat and the control accuracy are required。

LN81W系列波纹管调节阀

LN81W/82 series bellows single-seat control valve, based on the LN81/82 series control valve single-seat non-pressure balance structure based on the increase of bellows seal structure, pressure resistant elastic stainless steel bellows placed in the support parts and connected with the valve stem, with the filler to form a double seal, eliminate the medium leakage hazards。

LN82系列单座调节阀

LN82 series is one of the two base products of LN8 series pressure imbalance structure。Bushing and seat double guide, large flow capacity, excellent dynamic stability。The design of porous cylinder spool realizes the reasonable separation of throttling and sealing surface. The sealing surface is not directly eroded by high-speed fluid, and the sealing performance is good and reliable。使其能达到防闪蒸、抗空化、降噪音的目的。It is suitable for the control of clean media with fast flow rate, especially the gas with high pressure difference。
