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:Which brand of electric valve is good?
SIEMENS (Siemens, Germany); the main HVAC control valve; Johnson (Johnson, America); electric valve; Honeywell (Honeywell, USA); electric control valve for building; Wu mountain (YAMATAKE, Japan); valve; Bo Li Mou (Belimo, Switzerland); Danfoss (Danfoss ball valve, butterfly valve, Denmark); butterfly valve, gate valve, globe valve (aka ARCA, Germany); the control valve iResearch (ARI, Germany); the pressure relief valve, safety valve; Hank (HANK, Germany); pneumatic valve; KITZ (Japan); gate valve, globe valve, butterfly valve, ball valve, check valve; contact SIEMENS, Johnson, Honeywell, Shanwu, aka more;
Q:Is there a one-piece, two linkage valve?
Yes, three ball valves (T and L) are two. Switch more complex point of the valve is basically ball valve, such as central air-conditioning commonly used to the four - way reversing valve.
Q:What's the sewage treatment valve with?
Sewage treatment system valve requirements are not high, the use of butterfly valve is one of the most cost-effective.
Q:How to check the quality of the valve?
First of all, to check the appearance of the valve is smooth and smooth. Cast valves without sand holes and obvious flaws. Forged valves check nominal pressure or pound level.Second, check the material of the valve, that is, the material composition, this is very important, the material does not meet the standard on the device will be a big problem.Finally, check that the switch is sensitive and the signs are clear. Test pressure is the last step.Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q:How do you calculate the flow of the valve?
Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.
Q:Valve connections - two how do different connections work?
The connection of two different connection forms is achieved by a transition conversion connector
Q:What is a heavy body valve?
You should be asking what a heavy-duty valve is.This is only in the ordinary gate valve and cut-off valve on the distinction. Nowadays, ordinary gate valves and cut-off valves are divided into heavy-duty ones. Medium and light three kinds ~!
Q:What's the name of the valve?
Specific models only go to the original manufacturers to find, and want to use other valve replacement is not impossible, want to provide detailed parameters. Let's go to the valve manufacturer!

Q:What valves are needed on the construction site?
Order valve flow1, customers have special requirements for products, must provide the following instructions in the contract: a) b) the length of the structure connection form C) nominal diameter, full size, shrinkage, pipe size d) using medium and temperature and pressure range E) test, inspection standards and other requirements.2, the factory can be configured according to customer specific requirements of various driving devices.3. If the customer provides the type and model of the valve to be determined, the customer shall correctly explain the meaning and requirements of the model and sign the contract on the condition that both the supply and demand sides agree.4, futures, order customers, please call the letter in detail to tell you the required valve model, specifications, quantity and delivery time, location, factory information, billing information, delivery address. And in accordance with the total amount of 20% of the predetermined amount or full amount of money, timely import our factory account, and the rest of the payment before shipment, import, in order to arrange delivery in time.
