从India供应商批量进口A352 Lcb Carbon Steel Bal Valve

The A352 LCB Carbon Steel Ball Valve from SQK Valves Fittings & Automation Private Limited, based in India, is a full-port ball valve rated for service up to 600 PSI with a temperature span from -29°C to 425°C. The body material is A352 LCB low carbon steel, a casting grade chosen for its toughness in sub-zero conditions where standard carbon steels become brittle. The valve carries ASME B16.34 compliance and incorporates a blow-out proof stem design that retains the stem under pressure should internal retention fail.

LCB (Low Carbon B) steel in this valve is standard cast material per ASTM A352, with controlled carbon content to maintain Charpy impact resistance at temperatures below -46°C. The full-port bore matches the inside diameter of Schedule 40 pipe in the corresponding nominal size, minimising pressure drop and turbulence for pigging operations. Soft-seated variants typically use PTFE or RPTFE seats, though metal-seated constructions are available for high-temperature service above 250°C. The floating ball design in smaller sizes shifts downstream under pressure to achieve the primary metal-to-plastic seal.

Buyers in oil and gas upstream, petrochemical refining, and thermal power generation use this valve for on/off isolation in process lines, tank farms, and utility distribution. Offshore platform operators value the LCB material for its compliance with NACE MR0175/ISO 15156 sour-service requirements when specified with controlled hardness. Packaging and shipping terms from this Indian supplier are not stated in the listing data. Importers should confirm MOQ, Incoterms, and lead time directly with SQK Valves Fittings & Automation Private Limited, as the available profile shows a response rate of 0.00 with no recorded average response time.

SQK Valves Fittings & Automation Private Limited is listed as an imported-tier supplier in India with a harbour trust tier. The available profile shows no response activity, a 0.00 response rate, and zero average response hours, which means buyers should not assume rapid quotation turnaround. No verified factory, certification, or export licence details appear in the source data.

The company name suggests involvement in valves, fittings, and automation equipment, though the listing does not state manufacturing scope, in-house casting capability, or third-party OEM relationships. Importers should request the supplier's ISO 9001 certificate, material test reports (MTRs) with heat numbers, and pressure test certificates before placing orders. Direct communication is essential to clarify whether SQK holds API Q1 or API 6D certification, common requirements for oil and gas valve procurement.
