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.       Adopt high nickel ductile iron to manufacture stem nut so that T-type screw thread can cooperate stem to pass moment.
2.       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.     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.     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.     The head of stem is whole forged and connected with disc by "T" type trough to ensure the intensity. 
6.     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.     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.     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.

Welding Bar

Tungsten carbide welding bars are commonly used in the oil and gas industry for various applications. These bars are made from a combination of tungsten and carbon, which results in a very hard and wear-resistant material. Here are some specific uses of tungsten carbide welding bars in the oil and gas industry:

1. Hardfacing: Tungsten carbide welding bars are used for hardfacing applications, where a wear-resistant layer is applied to drilling tools, valves, pumps, and other equipment exposed to abrasive environments. This helps to extend the lifespan of the components and reduce maintenance costs.

2. Drill bits: Tungsten carbide welding bars are used to manufacture drill bits for oil and gas exploration. The hard and durable nature of tungsten carbide makes it ideal for drilling through tough rock formations.

3. Wear plates and liners: Tungsten carbide welding bars are used to create wear plates and liners for equipment used in oil and gas production. These plates and liners protect the underlying metal surfaces from abrasion and corrosion, ensuring the longevity of the equipment.

4. Valve seats and seals: Tungsten carbide welding bars are used to manufacture valve seats and seals for oil and gas valves. The high hardness and wear resistance of tungsten carbide ensure reliable sealing and prevent leakage in critical applications.

5. Downhole tools: Tungsten carbide welding bars are used in the manufacturing of downhole tools such as stabilizers, reamers, and drill collars. These tools are subjected to high pressures, temperatures, and abrasive conditions, and tungsten carbide helps to enhance their durability and performance.

Overall, tungsten carbide welding bars play a crucial role in the oil and gas industry by providing wear resistance, hardness, and durability to various components and equipment.
