Developed with optimized poppet‑sealing technology, SOLH VG342 pilot‑operated poppet solenoid valve is mass‑produced in‑house with sufficient stock. Serving global automation end‑users, this high‑flow vacuum compatible solenoid valve supports NC/NO/external‑pilot conversion. It delivers large‑capacity airflow, 1.8W low‑power option and 5Hz high‑frequency cycling. Oil‑free and zero‑leakage, it acts as reliable manifold main control valves for vacuum holding systems, large‑bore actuators and multi‑loop pneumatic automation lines.

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.

SOLH VR51 all-pneumatic two-hand safety interlock valve complies with EN ISO 13851 and EN574 safety standards. It integrates built-in 0.5-second synchronous detection anti-cheat logic; output air only activates when two buttons are pressed within 0.5s time difference, and air supply cuts off instantly once any button is released to avoid hand crushing injuries. Fully pneumatic without electrical components, it delivers intrinsic explosion-proof performance for dusty, humid and flammable workshops. The 3/2-way logic valve comes with standard exhaust silencer and wear-resistant lubrication-free spool for long service life. Equipped with φ6 / 1/4" flame retardant push-in fittings and optional mounting bracket, supporting rear or bottom piping layouts, it serves as standard safety interlock component for punching, riveting, cutting, injection molding and other high-risk processing machinery.
