According to reports, the Volvo Trucks Division plans to introduce a 13-liter LNG engine to the North American market in 2014. At the same time, it will also launch a new form of natural gas fuel - dimethyl ether (DME) as a further alternative energy sources.
As the cost of fuel increases, the company plans to continue working to improve efficiency. Volvo is also carefully considering whether to choose LNG to match compressed natural gas products. They claim that the new engine can increase efficiency and reduce CO2 emissions. In addition, Volvo also stated that the new engine can improve energy efficiency without sacrificing any torque or power. Currently, manufacturers have conducted road tests on this dimethyl ether-powered car. Volvo also expects that this fuel may become an option for large quantities of natural gas in North America.
Ron Huibers, president of sales and marketing at Volvo North America, showed that by using seven different types of fuel to drive cars in 2007, they have proven their strength. He further pointed out that they will continue to improve their work on the premise of using alternative fuels and power systems. In addition, he also mentioned their "comprehensive strategy, including natural gas, liquefied natural gas, and dimethyl ether with great potential, which means that with the improvement of infrastructure, we will have a complete natural gas solution."
Summary:
The valve has compacted structure, small flow-resistance with the flow pattern tend to be straight so that no sundries is kept inside. What`s more, it is light and convenient to install. The valve can be applied to cut off or regulate the flow of media. The valve can be actuated by operating lever, handle wheel, electric actuator or pneumatic actuator.
Unique Design:
The disc and the stem are connected without the structure of pin bolts, which guarantees no inner leakage.
Sealed surface of the disc is spherically shaped, which promotes the sealing capacity and increases the durability, which is to say even if opened and closed with pressure more than 50000 times, it remains no leakage.
Upon requests, the disc can be coated with Nylon or F46, Excellent anti-corrosion.
The valve body is coated with epoxy resin without any exposure of iron.
Reliable Sanitation:
The epoxy resin and rubber used comply with sanitary standard DVGW
Appling Area:
The valve can be used in water supply and drainage, disposing of polluted water, heat supply, gas, ship industry, metallurgical industry, energy system and textile and so on, especially applicable to those occasions that bi-directional sealing and valve body are easily eroded.
