Product Description:

1.Technical Date:

Size: DN20-DN800

Nominal Pressure: PN10/PN16/PN25

Operation Temperature: ≤80°C

Suitable Medium: Water


400 x flow control valve consists of the main valve, flow regulating valve, needle valve, pilot valve, ball valve, micro shape filter and pressure gauge of hydraulic control of system. Use of hydraulic automatic operation, control and adjust the opening of the main valve, made by the main valve flow rate remains constant.

400 x flow control valve with hydraulic control on our own efforts, do not need other devices and energy, easy maintenance, stable flow control. 400 x flow control valve is widely used in water supply network system of high-rise buildings, residential and urban water supply engineering.

When the valve from the inlet water supply, water flows through a needle valve in the main valve control room, and after a pilot valve, ball valve, from the main valve control room to export, the main valve in the fully open or floating state. Setting the upper master valve flow control valve, can be set in a main valve opening. Adjust the opening of needle valve and regulating valve spring pressure, can keep the main valve opening in setting the opening, and pilot valve to automatically adjust when pressure changes, the flow rate unchanged.

Q:What are the ten major brands of China's valves?
In the fluid piping system, the valve is the control element, its main function is to isolate the equipment and the piping system, regulates the flow, prevents the backflow, the adjustment and the excretion pressure. As the piping system selects the most suitable valve, it is important to understand the characteristics of the valve and the steps and the basis for selecting the valve. If you want to buy, you can choose the following aspects: 1. Select the valve according to the adjustment of medium parameters: two. According to prevent media backflow, choose the valve: three. According to the nature of the media, choose the valve. As for the brand if you can refer to the ten brands to buy China ten brands online, for example, Langao valve, a valve on the river, Amico, SF, card, open the valve on the market these are famous brands, you can refer to.
