SOLH IL100 booster relay is fully interchangeable with equivalent SMC models, acting as a 1:1 equal-pressure precision pneumatic volume amplifier. It achieves precise pressure tracking between input signal and output with linearity error within ±1% FS and maximum flow up to 6000 L/min, effectively eliminating slow response lag from long pipelines, large diaphragm actuators and big bore cylinders. Multiple thread standards including Rc, NPT and G are available. Besides standard temperature version, low temperature (-30℃), high temperature (100℃) and copper-free high-purity variants for semiconductors are optional. The anti-corrosion aluminum alloy body supports direct mounting or bracket installation with low steady air consumption. Widely matched with positioners for process control valves, long distance instrument air lines, heavy lifting/clamping cylinders and high-precision positioning loops; copper-free version fits semiconductor high-purity inert gas systems.

SOLH VQ21A is a pilot-operated 2-port solenoid valve exclusively customized for dry clean oil-free compressed air circuits. Optimized structure and seals guarantee stable low-pressure startup even under fluctuating air supply. Compact and lightweight with pre-installed φ6/φ8 one-touch push-in fittings for fast field assembly, it achieves ultra-fast response within ≤7ms to sustain long-term high-frequency purging and jetting. Lubrication-free elastic seal and IP65 dust & drip-proof housing resist oil contamination and vibration. Optional tool-locked manual override is available, supporting single standalone or manifold stacking mounting. Widely applied in dry air pipelines, workpiece dust removal, cooling and exhaust control for electronics, packaging and food automation equipment.

Switchgear Enclosure Panel – Product Details and Applications A switchgear enclosure panel serves as a protective housing for electrical components used in low, medium, and high-voltage switchgear systems. Constructed from high-grade materials such as galvanized steel, aluminum, or stainless steel, these panels ensure safety, durability, and optimal performance. They play a crucial role in preventing unauthorized access, safeguarding operators from live electrical parts, and shielding sensitive equipment from environmental factors like dust, moisture, and corrosive agents. Additionally, many panels feature a corrosion-resistant coating, enhancing their longevity in harsh industrial or outdoor settings.

FN18-D is a general purpose, three-pole, load break switch that offers switchgear owners and assemblers the advantages of an advanced interrupting technology and proven, dependable performance in a compact design.
