OEM/ODM API602 Forged Gate Valve Manufacturer & Factory in China

* Robust Forged Body: Made from forged steel materials such as A105N, F11, and F22, with a variety of special materials available upon request, including stainless steels (e.g., F304, F316) and alloy steels (e.g., Hastelloy, Monel).
* Low-Emission Design: The stem packing is pre-compressed with graphite packing and gaskets, effectively controlling fugitive emissions and ensuring a high-integrity seal. Compatible with API 624 and ISO 15848-1 Emission Standards.
* Double-Protected Bonnet: Options for a bolted or welded bonnet are available. The welded bonnet design offers double protection against leakage through both the body/bonnet threads and a strength-weld.

* Solid Wedge: Its angled design facilitates easy opening and closing for a hermetic seal, and it can handle fluids with a high solids content.
* Hardfaced Seating Surfaces: The seat rings are hardfaced with Stellite No. 6 or other cobalt-chrome alloys to enhance resistance to wear, corrosion, and erosion.
* Fully Guided Wedge: The fully guided wedge reduces wear on the seating surfaces, extending the valve's service life.

* Diverse End Connections: Available with various end connections, including Socket Weld, Threaded, and Flanged (Raised Face or Ring Type Joint) to suit different piping systems.
* OS&Y Rising Stem: The precision acme double-threaded rising stem design ensures quick operation.
* Blowout-Proof Stem: The stem-to-wedge connection is specially designed to prevent stem failure outside the stuffing box pressure boundary, even under severe loads.

* Field Injection Ports: Optional field injection ports can be added for the precise application of low-emission injectable packing.
* NACE Compliance: Valves can be supplied in compliance with NACE MR0175 or MR0103 standards for service in corrosive environments with hydrogen sulfide (H₂S).
* Other Customization Options: Additional customized designs are available upon request, such as double packing, leak-off connections, and live-loading.

Our valves are meticulously designed and tested to meet the most stringent international standards for fugitive emissions. We hold the ISO 15848-1 certification, providing our customers with a high-performance, low-leakage solution.
* Verified Performance: Our valves have successfully passed mechanical endurance tests of 205 cycles at 400°C and Class 1500 pressure, with tests witnessed by TÜV SÜD and executed by Wenzhou Haichuan Inspection Co., Ltd.
* Leakage-free Operation: The test results show a stem leakage value of 2.89×10−6 mbar.l/s, which is significantly lower than the ISO 15848-1 required value of 2.84×10−5 mbar.l/s.
* Extended Qualification: This certification extends to all valves with a stem size from 8mm to 32mm and a pressure rating up to Class 1500, ensuring consistent quality across our product line.
