The much-anticipated Christmas is coming! This year, in order to let our business partners receive gifts before Christmas, DERVOS started prepping a month in advance! First, the selection of gifts. Actually, our sales often pay attention to the preferences and needs of their respective customers during the daily communication, so they can also choose gifts that meet customers' wishes as well as are full of traditional Chinese characteristics. Second, the packaging of gifts. In order to let you receive the most exquisite gifts, keep the joy of opening presents, each gift is beautifully packaged. In addition, there are handwritten greeting cards for each sale. Finally, the delivery of gifts. In order to prevent Christmas gifts from being impacted during transportation, DERVOS wrapped several layers of shockproof pearl cotton and buffer film on the outermost layer of Christmas gifts, so that our partners can receive a perfect box of gifts. DERVOS looks forward to seeing your smiling faces when you receive the gift. As of today, DERVOS has received many thanks and praise from friends! And we hope that DERVOS's gifts can accompany you through a wonderful Christmas. DERVOS wishes you and your loved ones on the occasion of Merry Christmas and a prosperous New Year in advance!

Bellow seals globe valve is a valve used to control the flow rate. Bellow seals globe valve adopts a bellow structure inside, and the lower end of the stainless steel bellow is welded on the valve stem to prevent the process fluid from corroding the valve stem. It eliminates the disadvantages of fast aging and easy leakage of ordinary valve stem packing seals, not only improves the energy efficiency, increases the safety of production equipment, reduces maintenance costs and frequent maintenance, but also provides a clean and safe working environment. It is suitable for pipelines of steam, flammable, explosive, heat transfer oil, high-purity, toxic and other media. Advantages: 1. Double sealing design (bellow + packing), if the bellow fails, the stem packing will also avoid leakage; 2. It is not easy to leak and meets international sealing standards; 3. There is no fluid loss, reducing energy loss and improving the safety of factory equipment; 4. Good anti-friction performance, long service life, reduced maintenance times, and reduced operating costs; 5. Strong and durable bellow seals design ensures zero leakage of the valve stem and provides maintenance-free conditions; 6. Intuitive indication of valve stem lifting position.

OSEA (Offshore Southeast Asia) is one of the largest Oil and Gas Events in Asia. OSEA returns in 2022 as an in-person event at the forefront of offshore oil, gas and emerging zero carbon energy sources. OSEA returned from 15 -17 November 2022 to pioneer a global shift in the energy industry. Our agent in Singapore participated in OSEA, and brought our VALVES to meet you! Our products in this exhibition include Bellow Seals Globe Valve, Cryogenic Sleeve Type Plug Valve and etc. Although only some of our products are displayed on the booth, audiences can learn about our rich product categories and factory through videos. Apart from the products exhibited, our products also cover Ball Valve, Gate Valve, Butterfly Valve, Check Valve, etc. We still maintain the heart of providing you with quality services and excellent products.

The flat gate valve is a sliding valve whose closing part is a parallel wedge. The closing part can be a single gate or a double gate with a spreading mechanism in between. Flat gate valves can be divided into flat gate valves with diversion holes and flat gate valves without diversion holes according to the gate structure. Balanced plate valves with diversion holes are used for pipelines transporting oil and natural gas. For pipelines that do not require sweepers, flat gate valves without diversion holes can be used. Features of Flat Gate Valve 1. Small flow resistance. Since the wedge slides on the two valve seat surfaces, the flat gate valve is also suitable for fluids with suspended particles. 2. It has a double block and bleed function. 3. Fireproof design. When the O-ring and PTFE are burned, under the action of fluid pressure, the wedge and the retainer, the retainer and the valve body form a metal seal, thereby isolating the fluid. In addition, the middle flange gasket and packing are made of graphite and metal materials to prevent external leakage. 4. Self-releasing function: When the pressure in the middle cavity is high, the fixer will be pressed back under the action of the fluid in the middle cavity, so as to avoid accidents caused by excessive pressure in the middle cavity.

The pipe plug valve is a shut-off valve used for long-distance natural gas pipeline and station control system, which is a special valve to meet the special requirements of natural gas pipeline. The valve is required to have special technical performance such as adaptability to harsh environment, service life of more than 30 years, two-way zero leakage, fire resistance and anti-static, acid medium corrosion resistance, and labor saving operation. The pipeline plug valve has the following characteristics compared with the traditional bushing plug valve: ① It has reliable sealing, long service life and is sealed by the cone surface. The sealing contact surface is large, and the oil film plays the role of lubrication and sealing. ② The valve torque is small and the operation is labor-saving. The plug cone is installed upside down. ③ The valve cover at the bottom of the valve body is equipped with an adjusting support, which can adjust the position of the valve core. Under high temperature working conditions, the thermal expansion of the plug can avoid the sealing pair from being wedged by its lifting. ④ The design of valve stem anti fly out, O-ring and graphite packing, and triple valve stem seal filled with sealing grease meet the leakage requirements. It can work reliably for a long time without fastening and maintenance, and has fire protection function.

The plug valve is a quick opening and closing straight through valve. Because the movement between sealing surfaces has a wiping effect, the sealing surface can completely prevent contact with the flowing medium when it is fully opened, so it can usually be used for media with suspended particles. Plug valves are also widely used in industry. Performance Characteristics of Plug Valve: 1. Excellent high and low temperature performance, good pressure resistance. 2. Excellent sealing performance. 3. The material has strong adaptability and wide temperature range. The applicable temperature range of the material is - 40~+200 ℃. Application of Plug Valve: 1. Plug valves are widely used in oilfield exploitation, transportation and refining equipment, petrochemical industry, gas, natural gas, liquefied petroleum gas, HVAC industry and general industry. 2. The plug valve is also suitable for conveying liquids containing suspended solids and particles. The straight through plug valve can transport materials containing crystals with thermal insulation measures. The application scope of the plug valve is becoming wider and wider, and the oil seal plug valve with forced lubrication has also appeared, which has better sealing performance, saves effort in opening and closing, and prevents the sealing surface from being damaged.
