Down-extend feeding valve

Properties and Uses: 
Easy to operate, there is no open flow resistance; Valve clack simple assembly and maintenance, reasonable structure Seal, Seal ring replacement convenient and practical. 
Structure: The main by the body, Valve clack, Seal ring, Valve rod, bracket, valve Gland, handwheel, Flange, nut, screws and other parts. 
The main parameters: 
Nominal diameter DN, feeding valve rated flow coefficient KV, feeding valve Nominal pressure and differential pressure, feeding valve body and valve components Materials, feeding valve flow characteristics, feeding valve Suitable temperature, feeding valve supply voltage and control signal, feeding valve with or without attachments etc. this class Valve in the pipeline should generally be installed horizontally. 
body Materials: Cast steel, Stainless steel, 316L. 
Working pressure 0.6-2.5MPA, Working temperature -20 °C -425 °C. Valve caliber DN25-DN300. 
Connection: Flange Transmission:. Manual, pneumatic. 
Applicable medium:. Oil, acids, Corrosive medium other manufacturing Standard: GB. 
The valve consists of 1.body, 2.Valve clack, 3.Seal ring, 4.Valve rod, 5. bracket 6. valve Gland, 7. handwheel, 8. Flange, 9.nut, 10. screws, etc. component parts 
feeding valve is mainly used for reactors, tanks and other containers at the bottom of the discharge, discharge, sampling, and no dead zone off operation. Flange welded to the bottom by means of Valve bottom tanks and other containers, thus removing the process medium residual phenomenon container exports. feeding valve according to actual needs, put the bottom structure is designed as flat type, body of V type, and provides two ways of working to enhance and fall Valve clack. body cavity there is erosion-resistant, corrosion-resistant Seal ring, in turn Valve moment, can protect the body not being medium erosion, corrosion, and Seal ring for special treatment, the surface hardness of HRC56-62, with high wear and corrosion resistant features, Valve clackSeal required when the cover are surfacing carbide, Seal deputy with thread Seal, Seal ensure reliability and prevent scarring. while taking a short trip Valve clack design.
