Self-Seal Gate Valve

"Self-Seal Gate Valve" is listed under  ValvesCategory

Self-Seal Gate Valve ¦ Character Found the hand-wheel with forgeable cast iron and increase its friction to convenient for open and close the valve. At the same time, you can also choose impact type hand-wheel. 1. 160 160 160 160 160 160 Adopt high nickel ductile iron to manufacture stem nut so that T-type screw thread can cooperate stem to pass moment. 2. 160 160 160 160 160 160 In order to supplement solid lubricating oil termly and reduce on-off torque we set up thrust ball bearing and oil cup on the valve cover. Packing gland and cover are designed fission to assure the stem is concentric. 3. 160 160 160 160 The packing gland is assembled by knot-graphite, flexible graphite and middle packing ring to ensure the valve no leak and accord with the environment requirement. 4. 160 160 160 160 The connection of valve body and cover is self-sealing structure. At same time cuniform ring fits together with quarto-ring, so that higher pressure, better sealing performance. 5. 160 160 160 160 The head of stem is whole forged and connected with disc by “T” type trough to ensure the intensity. 6. 160 160 160 160 Jointing structure is adopted on the seat and hard alloy was welded on the sealing surface. All of these can ensure the long time work safe and credible. 7. 160 160 160 160 The material of disc is forge steel or flexible disc which have certain flexible compensation in high pressure condition and make the seal capability credible. 8. 160 160 160 160 Comfortable torque transmission structure. Hand-wheel or impact type hand-wheel transfers the torque to stem by stem nut. The stem is A182F6(1Cr13) which is forged and treated, so its hardness can achieve HB220~250. In order to reduce the wastage in the transmission process, we adopt high nickel ductile iron A439GR.D2 or copper alloy as material of stem nut whose hardness is less about HB50 than stem. We can add thrust bearing on the stem nut and set up oil cup structure on the large caliber and high pressure valve. If so we can add oil termly and keep it lubricating and make the valve has lighter torque all the time. ¦ Design and Manufacture Standard ?Design and Manufacture:API600 API6D GB12234?Flange:ANSIB16.5 JB/T79 GB9113?Pressure and Temperature:ANSIB16.34 JB/T74 GB9131?Face to Face:ANSIB16.10 GB12221?Butt Welding Connection Size:---?Test:API598 JB/T9092 GB13927
