Its products have been widely used in petroleum, petrochemical, chemical, metallurgy, electric power, water conservancy, machinery and many other fields.
As a leading manufacturer and supplier of bronze valves, Sedelon has produced and exported variety of excellent bronze valves, such as bronze gate valve , bronze globe valve, bronze check valve(swing check and dual plate-duo check valves) as well as bronze butterfly valve, bronze ball valve , bronze plug valves etc. These bronze valves have enjoyed a great reputation on the oversea market, today we specially recommend the bronze lug type double disc swing check valve. This is real photos from our recent orders to Germany marine companies(bronze lug type double disc swing check valve for 32inch-150lb) we can also make it to 52inch . Due to the high anti-corrosive properties of bronze valves, it’s widely used in environment protection and sea water desalination, high-rise building, drainage pipeline and the medium can be waste water, petroleum, chemical, salt water and so on. Our bronze product: Bronze gate valve, Bronze globe valve, Bronze check valve-bronze wafer swing check valve;bronze non-slam check valve(bronze nozzle check valve), Bronze butterfly valve(lug,wafer, flanged type) and bronze ball valve , bronze plug valve etc. Welcome your inquiries.
Sedelon® Ball Valves are made of variety of materials, Such as Bronze Ball Valves, Stainless Steel Ball Valves, Carbon Steel (Cast Steel ) Ball Valves, Forged Steel Ball Valves and Ceramic Ball Valves. Features: For Ceramic Ball Valves, the body and bonnet are made of steel, but the ball, seat and bushing are made of Ceramic (with high stability and hardness: HRC 90 ). That means the wet parts which contacting the medium are all made of ceramic.Ceramic ball valves do open and close function in excessively abrasive media. Their higher hardness makes them less susceptible to wear. They also deform less under load. Their service life is 2~4 times longer than that of steel. Sealing performance mainly depends on the ball and seat processing.As for this kind of ball valve, the balls are processed by advanced grinding equipment. The ball grinding and lapping performance are good such as roundness and roughness. When the ball touched and connected with the seat, good sealing performance can be achieved by the its self-lubricating property of Zirconia Ceramic. All these features make Ceramic Ball valves preferable to be used for medium that contains solid particle, such as gypsum slurry, ash water, puremix, mud,etc. These valves are widely used in following industries: Paper，Silicon powder，Coal chemical，etc.
There were many new and old customers to visit our booth D8423. They enjoy our products and have a great evaluation of our booth and our overseas trade team. In this Exhibition,our produce Bronze valves and Fugitive emission valves had been well received. Bronze valves have a good anti-corrosion property,and be widely used in sea water and marine.
Due to the lower alloying content, duplex stainless steels can be lower in cost, especially in times of high alloy surcharges. Additionally, it may often be possible to reduce the section thickness of duplex stainless steel, due to its increased yield strength compared to austenitic stainless steel. The combination can lead to significant cost and weight savings compared to a solution in austenitic stainless steels.
Welcome to visit Oil& Gas Indonesia 2015, We SEDELON are here for you.
Gate valve with extension stem is widely used at height work conditions, SEDELON lately has produced a batch of such gate valves to our Italian client who has said highly evaluation about the goods. The stem of gate valve can be extended according to the specified project, from 0mm~5000mm.
In order to strengthen the group cohesiveness and dip the potential capabilities of our Sedelon foreign trade team, we took part in the CTC Outward Bound Training, directed by CTC（ Cloud Top Commerce）-Wenzhou Business Association in 2015.

Pressure Seal check valves are designed for reliability in high velocity service applications to prevent backflow. Pressure seal check valves rely on the flow of the medium itself automatically open and close the valve,Then in order to prevent the media back. Sedelon®cast steel, Stainless steel and alloy steel ,pressure seal check valves are ideal for standard and critical power industry applications. The pressure seal bonnet joint eliminates the body/bonnet flanges, reducing weight and simplifying the application of exterior insulation. Contrary to bolted bonnet valves, internal pressure applied to a pressure seal valve forces the sealing elements into tighter contact – the higher the internal pressure, the tighter the seal.
Bronze is an alloy consisting mainly of copper, combined most often with tin, but sometimes also with other metals. Bronze resists corrosion (especially seawater corrosion) and metal fatigue more than steel and is also a better conductor of heat and electricity than most steels. It is applied widely in marine fields as a durable material of high hardness and good wear-resistance.
Congratulations! Sedelon ® Gate Valve has obtained Fugitive Emission certificates. Perfect design, Special facilities and excellenttechnique. Our products have been sold to Taiwan, America, Germany…ect,. Fugitive Emission Valves are thosevalves which bleed only a small amount of leakage to the external environment.In some European countries, there are customized companies to provide Fugitive Emission Testing Service for the local manufactures and end users. At present, theFugitive Emission Test Standards of International authority are the following three:EPAmethod21, ISO15848 and SHELLMESCSPE77／312.Among them, EPAmethod21 had detaileddescriptions of rules for the Fugitive Emission Testing Methods. ISO15848 and SHELLMESCSPE77／312 evaluate the performance of the valves in three aspects, such as Tightness Class, Endurance Class and Temperature Class. The classes are evaluated as A, B or C.
