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:HH valve company in the United Kingdom, how about the valve?
Our factory boiler has this brand of valve, used for many years, has been no problem, really good.
Q:What is the KVS in the valve parameter?
KVS meaning in valve parameters:Kvs is the coefficient of flow (also called circulation capacity).Kvs refers to both ends of the valve pressure difference of 0.1MPa, water density of 1g/cm^3, when the valve fully open flow. It is an important parameter of the control valve, reflecting the capacity of the control valve.Flow coefficient is a unit of time, in the test conditions, the pipeline to maintain a constant pressure, pipe flow through the valve mass flow, or mass flow. That is, the maximum flow capacity of the valve. The greater the value of the flow system, the smaller the pressure loss when the fluid passes through the valve. The CV value of the valve shall be determined by test and calculation.
Q:How many kinds of valves are there in the water pipes?
Valve is used as cut-off media, the flow through the fully open, then the pressure medium to run minimal loss. Usually does not require frequent valve for opening and closing, and maintain the gate fully open or fully closed condition. Not suitable for use as a regulator or throttle. For high-speed flow of medium, the gate conditions can cause vibration of the gate in the partial opening, and the vibration may damage gate and valve seat sealing surface, and the throttle gate will suffer erosion media. From the structural form, the main difference is that the sealing elements form. According to the form of seals, often divided into several different types of valve, such as: wedge gate valves parallel gate valve, parallel gate valve, wedge gate valve. The most commonly used form of wedge gate valve and parallel valve
Q:What is the difference between the valve before the pump and the valve after the pump?
Pump front valve: current limit; pump rear valve: limit pressure.Pump operating procedures: the pump must be closed before and after the valve, open the pump, slowly open the pump front valve, pump pressure normal, slowly open the pump, valve until all open. If the pump is in front and rear valves are opened, the pump is very easy to burn the motor.
Q:What are the definitions of internal, external and leakage valves?
Upstairs to say there is a problem. The leakage within the valve that is the reason of erosion wear medium makes the valve is not closed tightly, even if the valve screw (stem) screwed in place, because there is still a gap between the spool and the valve body, the medium can flow past. Outside leakage generally refers to the valve and connecting flange or threaded connection between the seal and guide...
Q:How about leaking water pipe valve?
1, if it is household valveA, the valve and pipe connections at the leakage, in the connection, do not rub tape (the best counter clockwise direction, so that when the valve is connected, the more twisted the more tight) ;B, if the valve itself in the leak, there are ways, it is necessary to open the valve, in which to add sealed or O ring, but it is recommended to replace a more convenient.2, if it is industrial valvesA, industrial valves leaking, if not the valve itself in the leak, then in the valve and pipe connections to join the sealing ring,B, if the valve itself is leaking, it is best to return to the manufacturer for maintenance, if not convenient, then only the manufacturers to come here for maintenance.
Q:The valve of the solar energy was broken by me. Do you know what is called?
An elbow, an outer wire, screw down the joint of the hose, the elbow is joined together.
Q:Is the valve clockwise?
The valve that can rotate is the principle of screw and nut. We can see that the switch is also buckled, so it is counterclockwise, the net is rotated out, clockwise downward, so it is off.
Q:What does "DN15" mean? What does "PN 16" mean?
Valve nominal diameter 15mm, valve nominal pressure 1.6MPa
Q:What is the main function of the valve?
Acting on switch control, flow regulation, remote control, etc.
