Import Forged Steel Check Valve — Buy in wholesale FOB from Supplier in China

The forged steel check valve offered by Wenzhou Domos Fluid Equipment Co., Ltd is a full‑port, spring‑loaded valve designed for one‑way flow control. It is supplied in nominal pipe sizes from 3/8 inch to 4 inch and conforms to ANSI Class 800 through Class 2500 pressure ratings. Available bonnet configurations include bolted, welded and pressure‑sealed types, allowing integration into a range of piping systems. The body can be fabricated from a selection of stainless steels such as A105, LF2, F304, F316, F304L, F316L, F321, F347, F11, F22, F5, F91, A350 and alloys meeting EN12516 specifications.

Trim components are offered in standard numbers such as Trim No.1, No.5, No.8 and No.12, providing options for seat and seal materials. The valve design follows API 602 and is manufactured according to ASME B16.34 standards, ensuring compliance with widely recognised pressure‑vessel criteria. End connections are provided per ASME B16.11 (socket weld) and ASME B1.20.1 (NPT) standards, matching common pipeline interfaces. Typical industry practice for this class of check valve includes a maximum operating pressure of 250 bar and service temperatures from - 30 °C to 200 °C, which aligns with the material grades supplied.

These valves are commonly used in petrochemical, water‑treatment and food‑processing plants where reliable back‑pressure protection is required. Procurement buyers such as plant engineers, EPC contractors and maintenance firms often specify the API 602 design and NACE‑approved alloys for corrosive service.
