Ductile Iron Grooved Flow Control Valve G400X-16Q

G400X沟槽流量控制阀是一种采用高精度先导式方式控制流量的多功能阀门。流量控制阀主阀安装在配主管道路需控制流量的管路中，保持预定流量不变，将过大流量限制在一个预不定期值，将上游高压减为下游低压，即使流量控制阀主阀上游的压力发生变化，也不会影响流量控制阀主阀下游的流量。G400X沟槽流量控制阀一改常规节流阀使用孔板或纯机械地减小流域面积的原理，利用相关导阀，大限度地减少能力在节流过程中的损失。如遇紧急情况G400X沟槽流量控制阀可以完全截止流量，避免损失。控制灵免度高，安全可靠，调试简便，使用寿命长。

Working Principle

When the valve from the inlet end of the water supply, water flow through the needle valve into the main valve control room, and through the pilot valve, ball valve out of the main valve control room to the outlet, at this time the main valve is in the full open or floating state. Adjust the flow control valve on the upper part of the main valve, you can set a certain degree of opening for the main valve. Adjusting the needle valve opening and adjusting the spring pressure of the pilot valve can keep the main valve opening at the set opening, and the pilot valve is automatically adjusted when the pressure changes to keep the flow constant.

Scope of Application

Urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection and other fields.

Product Features

G400X沟槽流量控制阀由主阀、流量调节阀、针阀、导阀、球阀、微形过滤器和压力表组成水力控制接管系统。G400X沟槽流量控制阀使系统无须另设专门的消防单独供水管网，大大地节约了建设成本和用水量。阀门控制灵敏度高，安全可靠，调试简便，使用寿命长。本产品利用水力自力控制，不需要其它装置和能源，保养简便，流量控制稳定。
