SGV Wedge Gate Valve

SGV Wedge Gate Valve

Gate valve can only be fully open/close, and can not be used as adjusting valve.
In a wedge gate, the seats are not parallel, but taper inward from top to bottom. The discs are also tapered.The trim of wedge gate valve is wedge, which is vertical to medium flow direction. When the discs are forced into the seats, the wedging action provides the sealing force. That is effective for sealing, but one of the drawbacks of a wedge gate is the discs can get ‘stuck’ in the seat, especially if there is a great change in system temperature from when the valve is closed.
Wedge gate valve can be a unique type called inflexible disc; and can also be a flexible wedge.Gate valve under low pressure occasion, disc is forced to set to guarantee sealing; while disc is forced to contact another seat by high pressure condition. There is a slot structure inside the cavity to make sure the disc will not rotate under pressure, and also guarantee there is no friction before close position between seat and disc, thus reduces frictions on sealing face.

Wedge gate valve of Sangong has following advantages

1. Product fabrication is strictly according to API 600, full port design, on full open position, valve disc is higher that flow direction to guarantee flow smoothly, reduce pressure loss, high transmission efficiency.
2. For carbon material valve, seat is forged, high density, good sealing capacity. Sealing face use 13Cr or Stellite hard alloy material, overlay net thickness is over 2mm, valve seat is threaded or welded on the valve body, easy to maintain and dissemble.
3. Adopt rising stem, stem and disc is connected by a T shaped groove, T head and stem is forged together to guarantee enough connection strength. Flexible disc structure can avoid stuck caused by heat inflation
4. Back seal design will protect packing when valve is fully opened. Packing is flexible graphite, good sealing capacity, and also venting system is available. Packing bush and gland are ball structure, pressure process will enable the stem to automatically centralized, avoid stem stuck.
5. Bolted bonnet structure and thick hex nut fastening parts will ensure reliable function. Gasket adopt flexible graphite twist stainless steel or octagonal ring to get good sealing effect
6. Top entry nut design assures that, when the valve is open, even if demount the hand-wheel, stem and disc will not fall down. Stem is made by Aluminum bronze, and both sides set bearing, all this made the valve easy to operate.

Bellow Seal Valves:Gate,Globe Valve

A valve with a bellows to seal off the stem enclosure is an ideal choice whenever leakage to the atmosphere is intolerable due to toxicity, chemical corrosion, radioactivity, other health or ecological reasons. In addition, seal welding the body-bonnet seal makes the valve hermetically sealed. The bellows is welded to the stem and to the bottom of the bonnet.
Supplier: Sangong Valve, China
Manufacturer: Shop in Wenzhou Oubei Industrial Park

Bellow seal valve is designed with bellow welded onto the bonnet and stem, so that when the stem travels drive the below expansion or decompression. It inherently eliminate the conventional design of possible stem packing leakage. SGV bellow sealed valves can achieve truly zero leakage; ideal for stringent leakage-free application like toxic and flammable services. Bellow seal valve is an ideal choice whenever leakage to the atmosphere is intolerable due to toxicity, chemical corrosion, radioactivity, other health or ecological reasons. In addition, seal welding the body-bonnet seal makes the valve hermetically sealed. Continue reading “Bellow Seal Valves:Gate,Globe Valve”

China Valve Industry

Valve oil, shipbuilding, nuclear industry, a variety of low-temperature projects, chemical, power station, long distance pipeline, aerospace and marine oil and other economic sectors indispensable fluid control equipment.

After years of development, China’s valve business volume ranks first in the world. There are about 6,000 up-scale enterprises totally, among them, there are 900 which annual output value over 500 million.

In china current valve market, in addition to low-pressure valve have achieve a level acceptable for the international market, the high-pressure valves still need to rely on imports. Thanks to continuous good macroeconomic situation, most production and sales targets  of valve industry are maintaining rapid growth, howover industry sales and profits dropped significantly over last year due to the price war. As the world economy revovery slowly, import and export of our valve products also increased gradually. Because of the high-end technology, compared with foreign manufacturers,there are still a wide gap in the next period of time. Product technology will be a bottleneck restriction of our valve products development.

In some opinion, China’s valve industry is now capable of producing more than a dozen categories of products, such as gate valve, globe valve, check valve, ball valve, butterfly valves, safety valve, relief valve, piston valves, plug valves, knife gate valve, slurry valve,  filter, foot valve, control valves, diaphragm valves, balance valve, solenoid valves, forged steel valves, needle valves, liquid level, flow meter, breather valve,  exhaust valve, flame arrester, instrument valves, copper valve, stainless steel valves, lined rubber lined valves, Pinch Valve,  power station valve, hydraulic control valve, vacuum valve, discharge valve, pneumatic angle seat valves,the U.S. standard valve, insulation valve, discharge valve, the maximum temperature reached 570 ℃, a minimum of -196 ℃, the maximum pressure of 600MPa, the maximum diameter to 5350 mm. In addition, according to the relevant departments of Statistics, China’s valve market turnover each year up to 500 billion yuan, of which more than 100 billion market take up by the foreign valve enterprises.

At present, China’s valve industry, there are still some problems, such as valve company in China are mainly low-level, small-scale, family-owned enterprises. About products, due to duplication of investment, technology transfer is not enough, the valve leading enterprise products in China is still low quality mass products. China’s production is currently widely impressed with following shortcomes,  leakage of various valves, internal leakage, the poor  appearance, short life, the operation is not flexible and electric valve actuators and pneumatic devices are not reliable, some of the products technology is only about 80s of the last century early international level, a number of high temperature and pressure and the critical need for the valve device is still rely on imports. Besides, A big gap between china and foreign is still existed in the industrial structure of China’s valve industry, valve industry, the industrial chain, and industry degree of specialization.

The reason of poor quality valve: the rapid market expansion, the original state-owned enterprises have been close, stop, merge,  transform, although a number of township enterprises developed rapidly, due to the low starting point of township enterprises, the technical power is very weak, poorly equipped , imitation products are mostly production, especially for the low pressure valve in water industry.

But the problem does not affect the future prospects of China’s valve industry wide. This is mainly due to the support of national policies and strong market demand for valve products, especially in several centuries, “natural gas”, “West to East”, “South” and started the project requires a large number of valve products supporting. In addition, China is faced with the arrival of the industrial age, the petrochemical industry, power industry, metallurgy industry, chemical industry and urban construction will push the use of large valve products. For example, the power industry,  coal units in large and medium-sized valves required for the project started was forecast totally:  153,000 tons valve, 30,600 tons in the average annual ; valve amount of the total demand of 39.6 billion with an annual demand amounted to 792 million yuan. In addition, China is becoming the world’s largest factory, manufacture for valve products with even greater space for development.

Thus, as long as companies can seize opportunities, strengthen research and development capabilities, and continuously improving product technology and product quality,  can have a bright future in the fierce market competition.
