LAM RESEARCH 50020R-10 Node Rocker Valve – Precision Gas Flow Control | HC-SFS202 Series
In a semiconductor etch or CVD chamber, a single failed valve can halt an entire production line. Uncontrolled gas flow leads to process drift, wafer contamination, and costly unplanned downtime that can cost fabs tens of thousands of dollars per hour. The node rocker valve is the critical on/off gating component that isolates and sequences process gases with millisecond precision — and when it fails, there is no workaround.
The LAM RESEARCH 50020R-10 is an OEM-specified Node Rocker Valve engineered for Lam Research etch and deposition platforms. Cross-referenced under part numbers 810-002895-232, 0041-81423, and C2088, and manufactured to HC-SFS202 series standards, this valve occupies a critical position in Lam’s gas delivery architecture. It is widely deployed across 200mm and 300mm fab environments globally, making it one of the most sought-after replacement components in the semiconductor MRO supply chain.
