Zhejiang World Brass Co., Ltd., located in Lupu Industrial Zone, Yuhuan, Zhejiang P.R. China., it was established in July 1999. It's a liability limited company, with the capital register of RMB25,080,000 and total capital of RMB85,000,000. We are mainly in producing and trading of valves, plastic items and fittings (with the material of hardware). We own more than 800 employees at present, includes 197 intendants and technicians, meantime 100 employees are qualified collegial diploma or above. We own 10 assembling and packing lines, 15 auto die-casting machines, 110 computerized machine tools, more than 600 instrumental tools and 1 computerized spectrum analyzer which is imported from Switzerland. We produce more than 45,000,000 pieces of brass valves with different kinds each year, and our main products are ball valve, check valve, globe valve, gate valve, bibcock, sanitary ware, flange valve, balance valve, pipe joint valve and boiler valve. 70% of our products are exported and the major markets are America, France, Italy, Spain and Egypt. We gained USD15,000, 000 from export in 2004 and it will reach USD30,000,000 in 2005.

From last year on, the price of the raw material and other costs are increasing rapidly, We are impacted a lot though our major markets are Europe and America. We adopt by the following in order to face the difficulties: Firstly, to enlarge the market of European and American, upgrade our products and increase the competitive ability and take the opportunity of the cooperation with the Global 500 companies, such as ITT, Leroy Merlin and Tecofi. Secondly, to raise the product competitive ability, the home brand and the rate of the marketing by introducing more experts in this field, paying more energy on technology and improvement, together with the absorption and the improvement of the design project and the market information of the famous companies to exploit more patents ( we have enrolled 13 internal brands and 5 international ones. Until April 2005, we have got 25 patents and the other 50 ones are declaring at the same time ). Thirdly, to share the resource and the information through establishing branches and offices abroad, getting the newly information of marketing, technology and material, and strengthening the cooperation with others.

Last year, the whole county achieved USD600,000,000 with the export of Sanitary ware and faucet, it is one of the major industries of Yuhuan. With the stable basis it is in the mature stage. The products are sold all over the world, and gain well reputations. Yuhuan was named as “The Capital of Valve in China” and “The Export Base of Hardware in China” by the National Light Industrial Association in 2003. Valves and their relatives is the supporter of the county's industry. Wherever at home or abroad, valves are the necessary of both industry and daily life. With the improvement of the economic level, the living condition and the development of the industry, especially in the development of the chemical industry, oil, environmental protection, food etc.. All the fragments will enlarge the requirement of valves. On the other hand, the manufacture center is moving to China, the original bases of valves such as Italy and Taiwan are hardly to compete with Chinese for the cheaper labor here. Along with the development of the living level and the world economy, the standard of either quantity or quality will be heightened sharply, though the valve industry is a labor intensive part with lower technical requirement comparatively. All of these make us a bright future of valve production.

We are a private company which is specializing in developing and manufacturing all kinds of brass valves, fittings, sanitary wares etc. We have made a rapid development after its establishment, and we are also the member of the Yuhuan Valve Association. We took the fourth place in the valve manufacturing. We attracted the talent by own wealth, technique and the market advantages. And the native mellow bases made us developed rapidly. We take “Quality as the life, innovation as the vitality” as the concept and pursue strictly supervision and efficient management. During the recent years, we have stored a lot of technicians and experiences, we have established global marketing channels, and the outstanding achievement and the technology support are increasing day by day. With all the advantages we gain a bright future.

Valve Series >> Bronze Balancing Valve

ZW101
Bronze Balancing Valve
Nominal Pressure:4.0MPa
Suitable Medium:Water,Non-Causticity Liquid & Saturated Steam
Working Temperature:-25ºC≤ t ≤ 150ºC
Parallel Thread Conform To ISO-228-1:2000

Patent No.: 200420047368·2
200430035248·6

Introduction of balancing valve:
1. Working theory and features

1.1 Working theory: changing the clearance among cartridge, seat and flow, changing the currency resistance though valve in order to adjust the circuit.
1.2 Balancing valve belongs to adjusting valve. It's specialize valve which can adjust the pressure and show the numerical value, it is also a kind of energy saving product with accurate controlled value.
1.2.1 Balancing valve is designed as the 55o with the cannon and the liquid, this can reduce the loss of pressure.
1.2.2 The body is made of bronze which erode-resistant. The seat is made of Teflon which can endure high and low temperature. The o-ring is made of EPDM which is very durable.
1.2.3 Bearing very good circuit-adjusting function and accurate controlled value of handwheel.

2. Using occasion
2.1 The designed temperature for using this valve is between -25ºC and + 150ºC. Nominal pressure is 2Mpa. The suitable medium is water and steam.
2.2 Balancing the flow in boilers and chillers
There are always parallel connection installed several sets in one water supply system. The different resistance of the setups makes the different flux of the sets. It can make sure to obtain the enactment and ensure the safety of them if to fit balancing valves for each boilers or chillers.
2.3 Balancing the water flux of the ring pipelines
2.3.1 Can be fitted in the lateral return pipe of the first time pipeline.
2.3.2 It can make sure of the second time pipeline's flux same as the designed numerical value, and keeps each set working up to stuff. When the chiller needs to be connected with several refrigeration sets, it can be fitted in each set.
2.3.3 It can be fitted in the areal of heat supply system and be used for the flux balance keeping. It should be fitted at the entryway because of the different heat source and the different distance from the destination.

3. Installation and use
3.1 Install in water inlet pipe or return pipe
3.2 Install on straight pipe ensuring accurate measurement
3.3 If the original system is installed balancing valve, but the system need some changes or improvement, it is necessary to reset the water flow rate.
3.4 Designing ideal flow rate after the system is stable. Can not open it at will and seal it by aluminum and fixing.
3.5 This valve has two sample points located in front and back faces. It is convenient for measuring of different direction.
