过滤活塞式安全泄压/持压阀
Filter piston safety relief/holding valve
本阀是利用管路中的水压自动操作主阀瓣的上下移动，控制阀门的开度，调节下游压力使其维持在导阔弹簧设定值上,当下游压力超过设定值时，减压阀将自动关闭，进口压力怎样波动都可输出稳定压力。下游流量怎样变换都能维持稳定的设定值。同时通过导阀调节的出口压力调节范围大，可达到阀前压力10-80%。一般用于生活给水、消防及工业给水
系统。
压力等级：PN10(调节范围01-08MPa)
PN16(调节范围02-14MPa)
PN25(调节范围03-20MPa)
规 格：DN40~DN200
The valve uses the water pressure in the pipeline to automatically operate the up and down movement of the main valve disc, control the opening of the valve, adjust the downstream pressure to maintain it at the set value of the width guide spring, when the downstream pressure exceeds the set value, the pressure reducing valve will automatically close, and how the inlet pressure fluctuates can output stable pressure. How to change the downstream flow can maintain a stable set value. At the same time, the outlet pressure adjusted by the pilot valve has a large adjustment range, which can reach 10-80% of the pressure before the valve. Generally used for domestic water supply, fire protection and industrial water supply
