Project Name: ECOFUEL INNOVATION PROJECT Year：2017 Introduction: In 2017, we provided a major number ofvalves from regular gate valves to safety relief valves to an environmental project lead byECOFUEL, an emerging Canadian player inclean technology. It is atentative project for sustainable diesel production from solid waste.Dervos is proud to bea part of this fuel innovation actionand offers 136 sets of our reliable and outstanding valves for it. SEGMENT BALL CONTROL VALVE It’s also called V type ball valve, whichhasthebest regulating performance in ball valves. Plus cut-down function between the V-shaped slit and the metal seat, this kind of ball valve is particularly suitable for medium withfibers, solid particles and slurry. KNIFE GATE VALVES As the mediumcontains wooden debris and slurry, knife gate valves are suggestedin this condition for its good cut-down performance. THREE-WAY SPLIT FLOW VALVE Remotely controlled by electric actuators, this valvecan split the flow into twostreams andachieve precise controloverprocess parameters for fluid. SAFETY VALVE Conformed to API520 and API526, thesesafety valves arecustomized according toon-siteworking pressure, temperature and flow capacity for over-pressure protection.

Just like there are different advantages between lug or wafer type butterfly valves, 2 piece type and 3 piece type ball valves also have their edges. What below are some of the important factors when considering choices between the two types.   1. Design 2. End connections 3. Installation 4. Performance 5. Ease of maintenance   Design As their names imply, a 2-piece ball valve has two distinct pieces – one piece is an end connection and the body and a second piece, which has the other end connection as well as the valve trim.   A 3-piece ball valve has three body pieces – 2 ends and a center section that holds the valve trim. The three parts are bolted together around the three sections.   End Connections Because of their designs, two-piece ball valves are limited in the type of end connections they can make. They are usually limited to threaded end connections.   Three-piece ball valves have a swing design that allows for welded end connections, so socket and butt weld ends are often feasible.   Installation Its simple design makes 2-pc ball valve one of the most common types in many industries. Due to this simple design, the 2-pc ball valve is a lightweight solution for manual and automatic fluid or gas control.   If the end connection is threaded, the installation of the 3-pc type is also very straightforward. When it is necessary to weld the end, in order to prevent the valve seat and the sealing ring from being heat damage, the device have to be partially disassembled during the installation.   Performance The simplistic design of 2-pc valve allows itself, generally, a better Cv value. The seats, seals, applications and other parts in performance are more decisive than the design type.   Ease of Maintenance The oscillating design of the 3-piece valve allows the body section to remain in place while the valve section swings up and out of the line for cleaning or servicing. This feature makes the 3-pc stand out from the 2-pc, whose design does not allow for any maintenance. Applications where the media is thick or viscous, or where lines must be cleaned between batches, are almost always the domain of the 3-pc valve.   summary Based on the above information, the consideration of 2-pc or 3-pc must include various factors, including the length of the production line through its medium, flow, weight, and maintenance plan. The good news is that our technical sales staff will be more than happy to discuss these factors so that you can make the right decision.   Xiamen Dervos has served countless industrial, commercial, and municipal clients for over 10 years. We have supplied thousands of common valves, customized products, electric and pneumatic actuators and so on to customers worldwide.   If you would like to know more about our valves, services, or other products, any message or inquiries are welcomed.

A Chinese saying goes that knowledge begins with practice.It is an essential principle that we must combine theory with practice. And, then, as we planned in the mid-year meeting this year, the first group of our sales have arrived factory to launch a 3-week long field study there. This trip is aimed at promoting Dervos sales' acquaintance of valves with gate valve, globe valve and check valve take the main course of it. And essentially, what's more important is that we hope our sales could be professional and more professional. In this way can they better help you solve your problem and finish your purchase. Our factory prepared well for this factory study. FromInventory management,production line, technique learning to packing and shipping, a wealth of lessons awaits for our sales. During almost a month of field study, in addition to grasping the whole producing process, assembling and packing, our sales spent a great amount of time in the storehouse in where they could learn the properties, differences, uses of each component and the reasons for the selection of different valve accessories. This is just the first group, the rest of our sales, no matter experienced or unskilled, will attend the trip in the next batch. Dervos is well aware of the hard time the whole industry even the whole world is going through. What we can try our best is to trained ourselves harder and provide more thoughtful solutions.
