从China供应商批发进口3-1/16" 15k Hydraulic Fc Gate Valves With Api 6a — FOB条款

This API 6A compliant gate valve from Oilman Valves Co., Ltd. features a 3-1/16 inch nominal bore and a 15,000 psi (15K) working pressure rating, placing it in the high-pressure wellhead and christmas tree equipment category. The valve body and bonnet are forged from alloy steel, with the sealing surfaces of both seat and gate overlaid with hard alloy via welding (surfacing) to resist the erosive action of sand-laden production fluids and corrosive sour gas environments. The hydraulic actuator provides remote or automated operation, a requirement for subsea and platform installations where manual access is restricted. The FC (flanged, clamped or compact) end connection style indicates a compact flange or hub-clamp configuration rather than traditional bolted flanges, reducing overall stack height and weight.

The stem design incorporates a rising or non-rising stem option with position indication, allowing operators to verify valve status visually. The lip-shaped combined seal structure for seat, gate, and stem uses imported elastomer or thermoplastic compound materials, engineered to maintain seal integrity across pressure cycling and temperature excursions typical of deep-well production (often -20\u00b0C to 121\u00b0C or wider with specialised materials). The non-rubber secondary seal design protects the valve chamber from ingress of drilling mud, sand, and rock debris, which is critical in frac applications and abrasive flowback operations. Stem packing can be replaced under pressure (pressure-boundary maintenance capability), extending service life without system shutdown. Drive modes include manual, hydraulic, and gear operators, with the hydraulic variant using a linear piston or scotch-yoke actuator depending on torque and speed requirements.

Primary buyers include oilfield service companies, drilling contractors, and equipment rental firms operating in shale plays, conventional onshore fields, and offshore platforms. The API 6A monogram is mandatory for equipment used in wellhead and christmas tree assemblies under most North American and many international production-sharing contracts. Importers should confirm that Oilman Valves can provide API 6A product specification levels (PSL) certification, specifically whether this valve meets PSL-3 or PSL-4 for critical sour service, and what material class (AA, BB, CC, DD, EE, FF, or HH) applies to the body and trim. Temperature and material class selection determines whether the valve is suitable for standard, low-temperature, or high-temperature service, and whether it meets NACE MR0175/ISO 15156 sour service requirements.

Oilman Valves Co., Ltd. is based in Kaifeng City, Henan Province, China, a region with established foundry and heavy equipment manufacturing infrastructure. The supplier carries a 'harbor' trust tier classification, with zero response rate and zero average response hours recorded on the platform, meaning no historical communication data is available for prospective buyers to assess. The company specialises in petroleum equipment, specifically API 6A gate valves for high-pressure wellhead applications, though the profile does not indicate whether they are a pure manufacturer, a trading company, or an OEM with in-house forging and machining capability.

No information is provided on company history, year of establishment, number of employees, annual valve production capacity, or major client references. The supplier does not state API monogram licence status, quality management system certification (ISO 9001, API Q1), or whether they maintain an API-approved quality program. The address format in the source data suggests a potential administrative or sales office rather than a manufacturing plant; buyers should request the actual manufacturing site location, welding procedure qualifications (WPS/PQR), and non-destructive testing capabilities (radiographic, ultrasonic, magnetic particle, liquid penetrant). Verification of API 6A adherence through an API auditor or third-party inspection is advisable before placing production orders.
