SOLH HLQ / HLQL twin-shaft slide cylinders adopt recirculating ball linear guides, including HLQ compact standard version with side-mounted cylinder and ultra-rigid symmetrical HLQL model. Bore sizes range from 6 to 25 mm with strokes 10–150 mm. The twin parallel piston rod design delivers strong thrust and excellent anti-torsion & anti-rotation performance. A built-in floating joint between piston and slide carriage offsets eccentric lateral loads. The base features 3-direction mounting tapped holes, while the slide carriage provides multi-surface fixture mounting holes and positioning pins; side slots for magnetic reed switches and built-in magnet come as standard. Multiple buffer options are available: double / single adjustable air buffer, hydraulic shock absorber and external stop blocks for smooth reciprocation and high repeat positioning accuracy. HLQ fits medium-small loads with limited space, while symmetrical HLQL handles heavy loads and severe eccentric offset. Widely used for automatic transfer, precision clamping and linear positioning in 3C, semiconductor assembly and testing equipment.

SOLH VG342 is a CE & ASME certified pilot operated poppet 3-port solenoid valve with superior zero-leak sealing and quick response. Equipped with standard 1.3W and energy-saving 0.4~0.55W coils, it supports switchable NC/NO logic without pipe modification, operating stably at 0.1–1.2MPa for compressed air, light oil and neutral inert gas. It adopts AISI 304 stainless steel poppet and ozone-resistant FKM/HNBR seals with built-in inlet filter, allows all-direction mounting and reaches 50-million-cycle service life. Perfectly matched with VBA boosters and VBAT air tanks, it applies to high-voltage switchgears, semiconductor, medical, automotive, petrochemical and precision automation lines, complying with ISO9001, CE, ASME and GB standards.

SOLH 2S series 2/2-way normally closed fluid solenoid valves include two full lines: direct-acting small orifice 030/050 models and pilot-operated large bore 150~500 variants, for automatic on-off control of clean water, compressed air, cutting coolant, lubricating oil and weakly corrosive liquid pipelines. The direct-acting version enables zero-pressure startup without minimum differential pressure limit, features compact size, universal mounting orientation and millisecond fast switching, ideal for low-pressure micro-flow applications such as single-point machine tool cooling, 3C micro air/water branches and mini cleaning equipment. The pilot-operated type requires a minimum 0.05MPa pressure difference for full opening, delivers ultra-large flow with low-wattage low-heat coils, suited for air compressor drain headers, main spray water lines and high-flow circulating water treatment pipelines. Standard NBR nitrile rubber seals are equipped, with optional acid & hot water resistant EPDM food-grade seals. Multi international thread standards (PT/G/NPT) and global universal coil voltages (DC12/24V, AC24/110/220V) are available, supported by DIN plug and wire lead wiring options. Heat-resistant coils allow long-term continuous energization. Selection guide: direct-acting type for pipelines with static pressure below 0.05MPa and small branch flow; pilot-operated version for G1/2 and above main headers with stable high pressure & large circulation flow. EPDM seal is mandatory for hot water and food-grade fluid media.

The Indoor High-Voltage Switchgear Ground Switch is a critical safety device designed for use in high-voltage electrical systems, ensuring safe grounding and isolation of equipment during maintenance and servicing. Suitable for voltage ranges from 12kV to 40.5kV, it provides exceptional resistance to short-circuit conditions and delivers reliable mechanical operation. Its compact and efficient design simplifies installation and ensures ease of use, making it an ideal choice for integration in high-voltage switchgear and substations. This grounding switch adheres to international standards, guaranteeing safe and stable performance in complex electrical networks.

SOLH TN cost-effective twin shaft cylinder adopts a single-piston dual guide shaft structure with slide bearing guidance for compact layout and excellent cost performance. It comes factory-equipped with built-in magnetic rings and an adjustable front rubber buffer for stroke fine tuning, delivering anti-rotation accuracy of ±0.2°. Synchronized dual shafts restrain torsion and swing to bear slight lateral eccentric loads. Three-direction mounting (top, bottom, side) is available, and side grooves support direct installation of magnetic switches without extra brackets. Two types are supplied: standard single-end rod TN and double through rod TNW, with TNW allowing fixture assembly on both rod ends for bidirectional synchronous centering motion. Compared with TR series, TN features smaller dimensions and lower cost without φ6 bore option; compared with CXS/CXSJ dual-piston twin cylinders, TN outputs single thrust with obvious cost advantages yet lower precision and load capacity. Its working pressure ranges from 0.15 to 1.0 MPa and ambient temperature adaptability covers −20℃~70℃. It is widely used for light-load positioning, simple pressing, workpiece stopping and short-distance transfer for general automation stations with moderate precision requirements and cost control demands. The S-type magnetic ring is standard for the whole series and cannot be removed; default Rc thread can be customized to G thread or NPT thread for overseas projects.
