China KQ2R different diameter pneumatic tube coupler Manufacturer, Supplier, Factory

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.

SOLH VNB114 series 2-way external pilot stainless steel solenoid valve, fully interchangeable with SMC VNB114. IP65 protection, NBR/FKM/EPR multiple seal options, NC/NO optional, Rc thread 1/8"-3/8". Ideal for weak acid-alkali, food-pharmacy sanitary fluid, semiconductor ultrapure water, vacuum and general industrial fluid pipeline on-off control.

SOLH RSQ fixed-height pneumatic stopper cylinders serve as standard limit actuators for automated conveyor systems. Equipped with ten interchangeable rod ends including hydraulic buffer lever styles for heavy shock absorption, they support four-side magnetic switch fitting and oil-free long-cycle operation. Differing from height-adjustable RSG models, its fixed rigid frame cuts on-site debugging time greatly. Our stable mass production ensures sufficient spot stock; these stoppers are widely deployed on electronics assembly lines, roller conveyors and heavy pallet positioning stations globally, delivering reliable workpiece blocking with affordable cost and strong impact resistance.

SOLH AF800 / AF900 large-bore high-flow main line air filter is fully interchangeable with equivalent SMC models, equipped with G1¼/G1½/G2 ports and maximum rated flow up to 20000 L/min, designed for air compressor main pipelines, full-line centralized air supply and high-flow multi-valve island pneumatic systems. Built-in centrifugal pre-separation structure removes over 95% condensed water, rust and large particles in advance; multi-layer fiber filter cartridges offer optional precision from 2μm to 100μm with standard 5μm for general use. The 45 cm³ water bowl supports three drainage modes: manual drain, AD47 NC float auto drain and AD48-6 NO float auto drain. Three bowl types are available: standard impact-resistant transparent PC bowl, heavy-duty metal bowl and explosion-proof metal bowl with liquid level sight window, while metal variants are recommended for painting, lithium battery explosion-proof and oily machine tool harsh environments. Hard-anodized aluminum body with straight-through runner delivers low pressure drop. Matched with AR regulators and AL lubricators to form complete AC800/900 air service units, widely installed at the front of air compressors for large CNC clusters, lithium coating workshops, auto painting lines and chemical explosion-proof plants, protecting downstream solenoid valves, cylinders and vacuum ejectors to reduce overall pneumatic system failure rates.
