Product Description:

A, product overview

ZLF (ZL - 4 m) series for flow control valve (self balancing valve) is a kind of intuitive easy flow adjusting control device, the network application of the valve can be directly set according to the design flow, the valve can be used in water, automatic eliminate the remainder of the pipeline pressure head and flow caused by pressure fluctuation is poor, no matter what the system pressure change all the set flow rate unchanged, the valve is finished at one time, these features make the network flow control to the net work for simple flow distribution, effectively solving the hydraulic imbalance between the network.

B,Technical parameters

1, medium temperature 0-150 ℃
2, work pressure differential 20-600 kpa

C, the performance and features
1, can be set according to the requirements of design or the actual flow rate, the system can automatically eliminate the differential pressure fluctuation, the flow rate unchanged; 
2, to overcome the system cold hot uneven phenomenon, improve the quality of heating (cooling);
3, completely solve the proximal differential pressure big, distal small pressure difference;
4, reduce system circulating water, reduce the system resistance;
5, reducing design effort, do not need to complex pipe network hydraulic balance calculation;
6, decrease the difficulty of the network turn complex net work is simplified to a simple flow distribution;
7, be exempted from the flow of heat pipe heat source switch more redistribution work;
8, flow display values are based on random calibration test bench, flow (m3 / h).

Q:Add a valve on the trachea, when the valve behind the use of gas units,
It seems that this is not a valve, it should belong to the flow switch
Q:What does the whole copper valve mean?
The whole valve is made of copper material. In addition to the ceramic core.
Q:What valve does the high pressure by-pass valve DN254 * 800 belong to?
High pressure bypass valve DN254 * 800 belongs to bypass valve.Function of bypass systemThe turbine by-pass device mainly has three functions of starting and overflowing:1 in the cold, warm and hot, the bypass system can realize the optimal unit start-up and shut-down in turbine operating conditions, start and stop curve can meet the requirements, two types of automatic and manual operation, with the establishment of the boiler steam temperature and steam turbine components. To shorten the start-up time.2. when the turbine is tripped, the bypass system can operate at a high speed and reach full open position.3., when the turbine load changes, the by-pass system has the regulating function, and the safety valve action can be avoided and the operation stability of the boiler can be improved when the instantaneous change of the moving state.The function of the bypass control valve:The main function of steam turbine bypass system is high pressure steam adjusting throttling and superheated steam cooling. The bypass valve to perform these functions at the same time and in low noise, small vibration, valve resistance to achieve its goal of temperature and pressure loss under the condition of touch.
Q:Our company is doing valve exports,
If the customs clearance order is required, the boxes, invoices, and contracts will not be needed. If the customs clearance is made, which port should be provided, the value of the goods, the weight, and the HS code for those
Q:Pump, valve, these belong to the material?
Pumps, valves are electromechanical equipment, belonging to a class of hardware fittings, but not material!
Q:How to use current to control valve opening and closing?
A relay or PID controller can achieve this operation, only need to set out, the valve can use electromagnetic valve, which belongs to a rapid opening and closing valves, only need to control the electric power to the valve can automatically open or closed, but the temperature change is large, if you want to keep the temperature constant. The best selection of regulating valve, constant temperature control valve will be before or after the valve, the main electrical control knowledge, do not know what I said is clear, remember the points, thank you!
Q:Which valves are used in the power station?
Power gate valve, also known as power station valve, is mainly used in various pipelines of fire power plants, cutting off or connecting pipeline medium.Applicable medium: non corrosive media such as water and steam. Compared with other valve products, the valve is characterized by high temperature and high pressure and unique self sealing design. The higher the pressure, the more reliable the seal is. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.Compared with other valve products, the gate valve of the power station is characterized by high temperature and high pressure. If only the pressure is lower than that of the universal valve, the temperature is lower than that of the general valve. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.
Q:Valve category can fill the trunk door, branch valve Mody?
Valve category refers to the type of valve, the big species are divided into: butterfly valve, gate valve, globe valve, ball valve, check valve, control valve, trap and electric valve,
Q:What is the difference between the adjustable range of valve 50:1 and 100:1?
One is 50 times, and the other is 100 times.
Q:How to check if the gas valve is open?
The gas valve has a handle, and the handle is parallel to the pipe and is opened, and the vertical is closed. If there is no handle, there is a rectangular main handle on the valve, the principle is the same as above.
