SedelonValve Company is established in 1998. Based in “the valve county”---Wenzhou, Zhejiang, China, this company integrates manufacturing and trading together.
The main products of this company are Bronze valves, API/DIN gate/globe/ check valves/butterfly valve/plug valve, ball valves and forged steel valves. Its products have been widely used in petroleum, petrochemical, chemical, metallurgy, electric power, water conservancy, machinery and many other fields.
In order to provide customer high-quality and better service, the company has equipped the system certification such as API6D, CE, ISO9001, TS, ect.
We have a strong technical and management team which is formed by advanced technical experts, engineers, managers, salesmen. We emphasize the importance of teamwork. Working together and helping each other, we are just like a big and warm family.
Positive Material Identification (PMI) is the analysis of a metallic alloy to establish composition by reading the percentage quantities of its constituent elements. The object of this nondestructive testing method is to identify metal alloys in place using a portable X-Ray fluorescent analyzer that determines the elemental composition of the material. At Sedelon, we have our own hand held Positive Material Analyser for confirming all stainless steel grades, Inconels, Hastelloys, Duplexes Steels and much more, without having to transport, alter, or damage the material. For Duplex Stainless Steel and Stainless Steel valves, PMI is conducted by using PMI XRF portable test gun, pointed at the external surface of completed valves. Parts of valves to be PMI tested are: a)Body, b)Bonnet, c)Stem, (for all valves having externally-exposed stems) By using PMI test, we can confirm all material received against orders raised by clients, and all tests can be witnessed by clients or their nominated inspectors.
Sedelon Valve Provide a lot of Pressure Seal Valves,Today we main talk about Pressure Seal Valves. Pressure Seal Gate Valves are suitable for the nominal pressure PN20.0 ~ 32.0 Mpa (900 lb to 2500 lb) and P (54) 100 v ~ P(57)170 v ,working temperature 540 ℃ or less (P (57) 170v of whom working temperature is 570 ℃) of oil, chemical industry, hydropower and thermal power plant under various working conditions such as the pipeline, cut off or connect medium. Valve filling flexible graphite, braided graphite and middle packing set combination.Both has good sealing performance and has certain strength, to ensure that the valve without leakage, accord with environmental protection requirement. Pressure is used to connect the valve body and cover the self-sealing sealing structure. Slot wedge zone of the sealing ring (mild steel or stainless steel) and the four open loop combination;Body parts corresponding carbide surfacing, forcing a reliable sealing ring deformation under high pressure. The higher the pressure sealing is more reliable. Feature: Pressure Range:(900LB-2500LB),(P (54) 100 v ~ P(57)170 v ) Applicable medium:water, oil, steam, etc. Operation mode: manual, electric, hydraulic, etc. Temperature:<=540 ℃, Connections:Butt Welding ends, Design Standard:AISI,DIN,JIS,BS ,Etc. Material:Cast Steel,Carbon Steel,Bronze,Stainless Steel ,Etc.
Heat treatment for Sedelon Valves Heat treatment is a method used to alter the physical, and sometimes chemical properties of a material. The most common application is metallurgical. It involves the use of heating or chilling, normally to extreme temperatures, to achieve a desired result such as hardening or softening of a material. It applies only to processes where the heating and cooling are done for the specific purpose of altering properties intentionally Types of Heat Treatment (Steel): 1) Annealing / Normalizing, 2) Case hardening, 3) Precipitation hardening, 4) Tempering, and Quenching The purpose of Heat Treatment:
