flanged gate valve for medium: water, gas, oil, natural gas and acid and alkali corrosive medium; Nominal diameter: DN15-800, 1/2 'to 24'; Drive mode: manual, gear, pneumatic, electric, etc. ; Valve material: cast steel, stainless steel etc. Applicable temperature: 180 ° C or less stainless steel valve, cast steel lamp 200 ° C or less, the cast steel weight of 425 ° C or less; ( ( Specific temperature range depends on the sealing material and medium characteristics) 1, the selection of flanged gate valve in line with the relevant standards at home and abroad, high material quality as a whole. 2 so as to meet the requirements of domestic and foreign advanced standards, reliable sealing, good performance, compact structure, reasonable design, rigid good, the valve channel smooth, small coefficient of flow resistance, good appearance. 3, using the flexible graphite packing, reliable seal, flexible operation of the light. 4. Seal of advanced and reasonable. Gate and seat sealing surface made of different hardness of too cobalt-based hard metal alloy. Sealing is reliable, high hardness, wear resistance, high temperature resistance, corrosion resistance. Good scratch resistance performance and long life. 5. Stem after quenching tempering and surface nitriding treatment, with good corrosion resistance, scratch resistance and abrasion resistance. 6, using the elastic wedge plunger structure, of large diameter thrust bearing, friction force is small, and is equipped with impact handwheels, easy opening and closing. Structure: a single elastic wedge gate, rigid wedge gate type. 7, can use a variety of pipe flange standard and flange sealing surface forms, can meet the needs of all kinds of engineering and user requirements.

Nowadays, the adoption of resilient seated gate valve in y gate valve industry is quite common.
