Import 5inch 5000psi Ppf Forged Gate Valve — Buy in wholesale FOB from Supplier in China

The 5-inch 5000psi PPF forged gate valve from Dongying Lake Petroleum Technology Co., Ltd. is a gear-operated, two-way slab gate valve designed for oilfield production service. It follows API 6A specification with a working pressure of 5000 psi, a 5-1/8 inch bore size (often referred to as 5-inch in trade shorthand), and includes a lower position indicator as a design modification from standard PFF configurations. The forged construction and pressure rating place it in the mid-range wellhead and manifold valve category for onshore oil and gas gathering systems.

Material class AA-FF covers the API 6A material specification range, with the specific grade selected based on service conditions including H2S partial pressure and chloride content. The working temperature designation covers L, U, and PU ranges, corresponding to standard, high temperature, and specific sour service conditions within API 6A definitions. PSL 1-4 indicates the product specification level, with higher PSL levels requiring more rigorous material traceability, non-destructive testing, and documentation. PR 1-2 refers to performance requirement levels that define testing protocols for pressure-containing and pressure-controlling functions.

This valve serves wellhead chokes, production manifolds, and gathering station piping where positive shutoff and full-bore flow are required. The gear operator allows controlled actuation against differential pressure, reducing operator fatigue compared with manual handwheel units in high-pressure service. Dongying Lake Petroleum Technology Co., Ltd. manufactures in Dongying, Shandong Province, a region with established oilfield equipment supply chains. Buyers should confirm current API 6A monogram licence validity, specific material grade for their service conditions, and lead time for PSL/PR level required.

Dongying Lake Petroleum Technology Co., Ltd. is located on Huanghe Road, Dongying, Shandong Province, postal code 257000. The supplier tier is imported with a harbour trust designation, meaning the profile was sourced from external databases rather than platform-native verification. Response rate and average response hours are both recorded at zero, indicating no inquiry response data is available rather than confirmed unresponsiveness.

The supplier profile provides no information about year of establishment, factory certification, number of employees, annual production capacity, or specific client references. No API licence number or quality system certification is listed in the source data. Dongying is a known cluster for petroleum equipment manufacturing in China, with numerous suppliers serving Sinopec and export markets. Buyers should independently verify API 6A monogram licence status through the API composite index, confirm the manufacturing scope covers the specific valve size and pressure rating ordered, and request a current quality manual or factory audit report before committing to volume orders.
