2.Feature

This valve is a valve with special functions, has good flow characteristic, reasonable distribution of flow, implementation flow quantitatively, effectively solve the heating (air conditioning) room temperature is uneven and problems that exist in the system.

As set in the valve opening degree of instructions, opening the lock and a small valve used for flow measurement of pressure, so as long as in the selection and the user entry fitted with appropriate specifications of the balance valve, special and intelligent instrument for the disposable lock after debugging, the system of the total water flow control in a reasonable scope, thus overcome the "big flow rate, small temperature difference" unreasonable phenomenon. This product is the ideal product in the heating system, high medium temperature is 200 ℃.

Q: What is the normal temperature on the valve?: At normal temperatures are below 120 degrees. A lot of valve sealing surface can only reach 120 degrees

Q: the use of natural connections, is strictly prohibited counterparts. What do you mean by "strong opposition"?: From the literal explanation, the strong counterpart connection is different from the normal connection. Valves are naturally connected to pipes or equipment, including threaded connections, flanged connections, clamp connections, welding, butterfly valves, clamp connections, etc..Strong mouth connection, similar to the butterfly valve on the clip connection, just outside of clamping method used in other valves (not seen on the clip connection with other valves), so this will depend on external interface of the valve (wafer type butterfly valve, said strong counterparts except).

Q: Chinese valve and a valve which is better?: Look what valve you use, ah, these two can be ah!

Q: What is the difference between the valve before the pump and the valve after the pump?: Pump in front of the gate valve + one-way valve, after the pump connected valve, so that in the regulation can be clearly aware of the actual pump lift is large, without the impact of system pressure.Valve is the general name of pumps and valves.A valve that is not used in a pump or with a pump.Pump and valve are often associated with the use of the occasion. In other words, where there is a pump, there is usually a valve, where a valve is often required. They are all used for liquid delivery.

Q: What's the difference between valves and valves without valves?: The advantage of carrying valves and venting valves is that they control the amount of exhaust and prevent other fluids from flowing out.

Q: What are the advantages and disadvantages of this method? Are there any other ways to adjust the flow rate?: Adjust the speed of the water pump to adjust the flow of the most appropriate, such as liquid or variable frequency control, with the switch pump outlet door to adjust the flow rate is the most uneconomical.

Q: How do you understand the valve Z41X-16?: This is a standard set, the landlord himself to check the JB/T308 standard, Baidu library, some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionZ = gate valve4 = connection: flange1 = structural form: open rod single gateX = sealing surface material: Rubber16 = nominal pressure: 1.6MPa16 there is no letter behind it indicates that the body is made of cast iron

Q: What do you mean by the 16 bit coding of the valve type?: Valve model is by the type of valve, valve drive, valve connection, valve structure, sealing material, valve body material code to indicate.1. Valve types are Z- gate valve, P- drain valve, Q- ball valve, D- butterfly valve, J- stop valve, etc.;2, the valve drive mode code by letters said, common 2- electric hydraulic, 9- electric, 6- pneumatic, 5- bevel gear drive, 3- turbo worm; manual do not need to write out3, the valve connection form code with letters to indicate, 1- internal thread, 2- external thread, 4- flange type, 6- welding, 7- pairs clamp type, 9- clamp, 0- card sleeve;4, valve structure code, for example: 0- 1- flexible gate valve, open bar wedge type single gate, 2- rising stem wedge gate, 3- parallel single gate, 4- double disk parallel, 5- dark pole single wedge gate, 6- dark bar wedge gate, dark 7- parallel single gate, 9- dark pole parallel gate;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber lining, Monel M-;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.

Q: What are the key valve enterprises in China? Mainly in those areas?: Chinese valve is mainly produced in Zhejiang, where Wenzhou, Shanghai there are a lot of Zhejiang valve in Wenzhou, but also Shanghai valve production, many are also Zhejiang boss, the key depends on whether you need what valve valve, the valve may be located in different regions is not the same

Q: Yongde jiekelong valves and valves of the good faith: Interior decoration is the most cost-effective brand, switches, sockets, Zhejiang, Yongkang, France and Germany electrical appliances. Plumbing valve, Zhejiang, Yongde, Yongkang letter. Bathroom accessories Fujian Nanan Jomoo bathroom.
