Import Fsv-4a Forged S.S. Thermodynamic Steam Trap — Buy in wholesale FOB from Supplier in India

The FSV-4A is a forged stainless‑steel thermodynamic steam trap supplied by Aps Marines & Logisitics in India. Its body conforms to the FSS (AISI-410) standard and incorporates an in‑built strainer. The trap features a renewable seat and renewable disc, with a trim of SS AISI-410, and the end connections are screwed female BSP taper threads to BS 21. Tested to a pressure of 900 psig, it operates safely up to a hydraulic working pressure of 450 psig and a maximum temperature of 400 °C.

AISI-410 provides good resistance to high‑temperature steam and moderate corrosion, which is typical for steam‑trap applications in power generation. Renewable seats allow on‑site replacement without dismantling the whole trap, a standard practice that reduces maintenance downtime. Industry guidelines often specify a flow capacity between 5 and 20 kg h⁻¹ for traps of this size, and inlet pressures from 0.1 to 2 MPa, which matches the typical operating envelope of the FSV-4A. The design follows ASME PTC 19.3 recommendations for thermodynamic traps, ensuring compatibility with most plant safety codes.

The unit is commonly installed in boiler feed lines, condensate return circuits and process steam distribution networks, where plant engineers require reliable condensate removal. Procurement usually involves bulk shipment in steel crates, with the exact minimum order quantity and incoterms to be confirmed directly with the supplier. Buyers should request the test certificate in Form III-C as issued by the testing body and verify payment terms such as L/C before finalising the contract.

Aps Marines & Logisitics is located at 1, 22, Asaf Ali Rd, Kamla Market, Ajmeri Gate, New Delhi 110002, India. The company is listed with a harbor trust tier on the platform, but its response rate is currently recorded as 0 % with no average response time. It offers engineered steam‑handling equipment and supplies test certificates with each supply, as noted in the product description. The profile does not disclose additional corporate details such as year of establishment or production capacity.

The supplier states that all forged components are manufactured to the specified material grades and undergo hydrostatic testing before dispatch. Certification is provided in the form of a Test Certificate III‑C issued by the testing body, which the buyer can request upon order confirmation. No further claims about ISO or other management system certifications are made in the listing. Prospective buyers should therefore verify any additional quality assurances directly with Aps Marines & Logisitics.
