The valve relies on its own energy to maintain the outlet pressure stable at the set value, that is, the outlet pressure does not change due to changes in inlet pressure and flow rate. The inlet of the valve control system is equipped with a self-cleaning filter screen, which utilizes fluid characteristics to prevent suspended particles with high specific gravity and large diameter from entering the control system. This ensures smooth system circulation and enables the valve to operate safely and reliably. The system operates sensitively and has a long service life.<br><br><br>Main external connection dimensions<br><br><table style="WIDTH: 650px; BORDER-COLLAPSE: collapse" border="1" cellspacing="0"

http://www.91way.com/info_en/5110.html 减压阀 2026-1-21 18:53:36 YG13H减压阀主要用于蒸汽管路，适用于进口压力变化大，流量变化大的蒸汽管路。YG13H减压阀属于先导活塞式减压阀.由主阀和导阀两部分组成。主阀主要由阀座、主阀盘、活塞、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节调节弹簧压力设定出口压力、利用膜片传感出口压力变化,通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小，实现减压稳压功能。　　 <BR><BR>YG13H减压阀在普通减压阀基础上做了以下改进，加大了活塞面积，改变了节流结构，改变了密封形式，改进了导阀结构和调节弹簧形式，从而从以下几方面提高了产品的性能。&nbsp;<BR>1、提高了对出口压力变化的传感效能，提高了灵敏度，大大降低了因上游压力变化，流量变化等因素引起的压力偏差。&nbsp;<BR>2、改善了流线分布，降低了噪声。&nbsp;<BR>3、改进了密封面结构，延长了密封面寿命。

减压阀 2026-1-14 15:07:16 Yk43X先导活塞式气体减压阀主要用于气体管路，如空气、氮气、氧气、氢气、液化气、天然气等气体。 Yk43X减压阀属于先导活塞式减压阀。由主阀和导阀两部分组成。主阀主要由阀座、主阀盘、活塞、缸套、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节调节弹簧压力设定出口压力、利用膜片传感出口压力变化，通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小，实现减压稳压功能。 <BR><BR>Yk43X空气减压阀外形尺寸 ( PN6.4-16.0 )： 单位：mm

Y13H减压阀主要用于蒸汽管路，起减压稳压作用。Y13H减压阀属于先导活塞式减压阀。由主阀和导阀两部分组成。主阀主要由阀座、主阀盘、活塞、缸套、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节调节弹簧压力设定出口压力，利用膜片传感出口压力变化，通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小，实现减压稳压功能。

Yt11H加大薄膜型高灵敏度减压阀特别适用于进口压力变化大，出口流量变化大，需要出口压力较好稳定的管路。Yt11H高灵敏减压阀是参考国外同类产品研制开发的，属于直接作用式薄膜弹簧减压阀，其突出特点是大大加大了膜片工作面积，因此，和同类减压阀相比，膜片对下游压力变化的传感特别明显，下游压力的微小变化（例如0.01MPa）都将引起膜片和阀芯明显的调节动作，从而大大提高了稳压功能。<BR><BR>Yt11H高灵敏度减压阀连接尺寸：

YG43H减压阀主要用于蒸汽管路，适用于进口压力变化大，流量变化大的蒸汽管路。YG43H减压阀属于先导活塞式减压阀。由主阀和导阀两部分组成。主阀主要由阀座、主阀盘、活塞、缸套、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节调节弹簧压力设定出口压力、利用膜片传感出口压力变化，通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小，实现减压稳压功能。 　　 <BR><BR>YG43H减压阀在普通减压阀基础上做了以下改进，加大了活塞面积，改变了节流结构，改变了密封形式，改进了导阀结构和调节弹簧形式，从而从以下几方面提高了产品的性能。&nbsp;<BR>1、提高了对出口压力变化的传感效能，提高了灵敏度，大大降低了因上游压力变化，流量变化等因素引起的压力偏差。&nbsp;<BR>2、改善了流线分布，降低了噪声。&nbsp;<BR>3、改进了密封面结构，延长了密封面寿命。

Y44H减压阀属于直接作用式波纹管弹簧减压阀。主要由波纹管、调节弹簧、阀座、阀瓣等零件组成，利用波纹管传感阀门下游压力驱动阀瓣，改变和控制阀门开度实现减压稳压功能。通过调节调节螺栓设定出口压力。 Y44H直接作用式波纹管减压阀调压、稳压动作灵敏平衡，适用于气体和液体介质的管路使用。 <BR><BR>Y44H直接作用式波纹管减压阀主要技术参数和性能指标 ： <BR><BR> <TABLE
