Products Details
QILONG covers ranges of CNC machines, and all parts are machined by CNC lathes and machining centers, which ensure the shape and position tolerance and accuracy of the parts, with all CNC controls the valve tests and valve performance are improved tremendously.
Design Features
QILONG top entry trunnion ball are manufactured in forged or cast material in high performance and manufactured to international standards like API 6D, API 6A, ASME B16.34 and customer specific requirements on request. Top-entry ball valves are easy to operate and maintain, simplifying in-line disassembly for trim inspection or repair, even when space is restrictive and requires limited maintenance. The top entry ball valves also have excellent corrosion resistance and excellent sealing performance at high and low pressures. The top entry ball valves can be applied for a wide variety of applications in the oil & gas, petrochemical, mining, and power industries when high quality, reliable valves are required. The top entry ball will be produced in cast or forged steel material form acc. to valve pressure class and service media critical or not, we also produce the cryogenic service top entry ball valve by different medium and low temperature service. Top Entry Ball Valves Production Range： Material type Forged steel or Cast steel carbon steel, LTCS, alloy steel, stainless steel, duplex steel, bronze, Inconel, Hastelloy, Monel, Incoloy etc. Material code WCB, LCB, CF8, CF8M, CF3, CF3M, A105, LF2, F304, F316, F304L, F316L Ball type Top Entry Ball Seat type Soft Seat (RPTFE, DEVLON, PEEK etc.) Customized Metal Seat available Size NPS 2”~24” (50mm~600mm) Pressure ASME Class150~2500LBS (PN16~PN420) Operation Manual, Worm Gearbox, Pneumatic actuator, Electric actuator, Hydraulic-electric actuator
The top entry ball valve forged material is in integrated forgings, which is more stable and reliable mechanically than casting under severe medium working conditions. The top entry ball valve can also be produced in cryogenic specific for application in LNG and liquid nitrogen service. With extended bonnet design, service low temperature -196°C. QILONG produce valve in live-load graphite API 622 and soft seat valve lip-seal sealing API 624 fugitive emission compliance.
