Ductile Iron Flow Control Valve 400X-16Q

400X flow control valve is a multifunctional valve which adopts high-precision pilot type way to control flow. Flow control valve main valve is installed in the pipeline of the distribution main road need to control the flow, keep the predetermined flow unchanged, limit the excessive flow to a pre indefinite value, reduce the upstream high pressure to the downstream low pressure, even if the pressure upstream of the main valve of the flow control valve changes, but also will not affect the flow downstream of the flow control valve. 400X Flow Control Valve changed from the conventional throttling valves to use the orifice plate or purely mechanically reduce the area of the watershed The principle of the use of conventional throttle valves using orifice plates or purely mechanical reduction of the basin area, the use of the relevant pilot valve, to minimize the loss of capacity in the throttling process. In case of emergency 400X flow control valve can completely cut off the flow to avoid loss. High control flexibility, safety and reliability, easy commissioning, long service life.

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

400X flow control valve by the main valve, flow control valves, needle valves, pilot valves, ball valves, microfilters and pressure gauges composed of hydraulic control receiver system. 400X flow control valve so that the system does not have to set up a separate water supply network for fire fighting, greatly saving the construction costs and water consumption. Valve control sensitivity is high, safe and reliable, easy commissioning, long service life. This product utilizes hydraulic self-control, does not require other devices and energy, easy maintenance, stable flow control.
