It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status.The shut position 1/4 turn could be in either CW or CCW direction. (S = SHUT, O = OPEN)Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications, where they are often preferred togatesandglobevalves, but they lack their fine control in throttling applications.SizeABDEPFHKTGNMC1/2"1511731304252709512.514151083/4"20117613042587510014.514151171"25148616050689012514141912711/4"321491160507610013516241914011/2"3817119200708110514017.524191652"5017127200709712015517.5241917821/2"65171362001021161401751924191903"76221643251021271501852028192034"9422178325102152175210202819229Investment Casting/Lost Wax Casting:1.Mold and Pattern MakingA mold is built to customer-provided specifications. Cold wax is then injected into the mold to creat a wax pattern/prototype that will hold precise dimensional requirements in the final casting2. Pattern AssemblyThe wax patterns are assembled onto the sprue.3. Dipping and CoatingSuccessive layers of ceramic and stucco are applied to the sprue assembly to form a hard shell.4. De-waxing and FiringThe molds are flash-fired to remove the wax and sprue materials and then heated to 1800° and placed on a sand bed, ready for pouring5. CastingMolten metal, up to 3000°, is poured into the hollow mold and then cooled.6. KnockoutThe ceramic shell is broken off, and the individual castings are cut away.7. FinishingExcess metal is removed, surfaces are finished, and castings are heat treated.8. Testing and InspectionCastings undergo thorough testing and inspection to ensure that they meet dimensional tolerances and specifications.9. Packing and ShippingCastings are securely packaged for shipping to the customer.Investment casting also called silica sol casting, lost wax casting, precision casting. Material is stainless steel, carbon steel, alloy steel. Standard ofGB, ASTM, AISI, DIN, BS, JIS, NF. Our main material grade is 1.4408, CF8, CF8M, 4140, SS304, SS316, 40Cr, 42CrMo, etc.Advantages of Investment Casting:1.Large application. Not limit to size, thickness and structure, all can produce by casting. Flexible mode of production. Our casting parts mainly use for Pump & Valve industry, agricultural machinery, construction machinery, food machinery, marine hardware, auto parts, etc.2.A wide range of materials can be used. Extensive use of used metals and renewable resources.3.Castings have certain dimensional accuracy, small processing margins, the processing time and the metal material are saved.4.Low cost, good comprehensive economic performance. Low energy, material consumption and cost. VALVE DEscriptIONA ball valve is a form of quater-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the vavle handle. The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed,making for easy visual confirmation of the valve's status. The shut position 1/4 turn could be in either CW or CCW direction.(S=SHUT,O=OPEN)Ball valve are durable,performing well after many cycles, and reliable, closing securely even after long periods of disuse .These qualities make them an excellent choice for shutoff and control applications,where they are often preferred to gates and globe valves, but they lack their fine control in throttling applications.QUALITY TESTINGTo make sure the quality of sealing for both factory new valve and the valve after repairing ,pressure testing would be the last pace. The method we choose to test is based on the national standard or the international standard. American standard (ANSI/ASME,AP-I),German standard (DIN),Europe standard-(EN)and International standard (ISO)would be the most common choice. Hebei JY Precision Machinery Co.
