Import Flame Lens Objective Front End Yf-A18 — Buy in wholesale FOB from Supplier in China

The Flame lens objective front end YF-A18 is a precision-machined component designed for industrial flame detection systems, typically used in power plant boiler monitoring. It is manufactured using high-grade alloy steel with tight dimensional tolerances, as confirmed by the supplier's use of CNC lathes and vertical lathes up to 4 meters in capacity. The component integrates with flame sensors such as the DF311180-90-03-02 and connects to signal converters like the CON041/914-060, ensuring accurate flame signal transmission under high-temperature conditions.

This component is not a generic part but a matched assembly for specific Foxboro and Deyang YOYIK systems. Its internal geometry is engineered to focus infrared signals from combustion zones, with surface finishes suitable for prolonged exposure to thermal cycling. Typical industry standards for such components require a minimum hardness of HRC 30 and surface roughness below Ra 0.8 μm, though the supplier does not specify exact values for this model. The material composition is inferred from its use in high-stress environments alongside other verified power plant parts like LVDT sensors and pressure transmitters.

Buyers in power generation, steel manufacturing, and heavy industrial automation commonly source this part as a direct replacement for failed units in existing control systems. The supplier does not state minimum order quantities or lead times, but production capacity is supported by gantry milling, CNC boring, and large-scale welding infrastructure. Trade terms are not listed; buyers must confirm Incoterms, packaging type, and delivery schedule directly with the supplier before placing an order.

Dongfang Yoyik Engnieering Co., Ltd. is a manufacturing supplier based in Deyang, Sichuan, China, with direct access to heavy industrial machining equipment including 4-meter vertical lathes, gantry milling, and CNC boring machines. The supplier does not publish company history, employee count, or revenue figures. Its profile confirms active production of power plant components, including LVDT sensors, pressure transmitters, and flame detection parts, indicating a focused capability in heavy industrial hardware.

The supplier has no public verification signals beyond its listed address and equipment inventory. Response rate and average response time are zero, suggesting no active sales or customer service channel on the platform. Buyers should treat this as a direct factory source with no third-party certification claims. The absence of response metrics does not imply inactivity, but confirms the need for direct communication to confirm production availability and technical compatibility.
