SOLH SCV series dedicated air-operated coating valves include 2-way SCV12 and 3-way SCV13 for paint, thinner and purge air switching & fast color change control. Wetted parts adopt composite PTFE+FPM solvent-resistant seals, and isolation diaphragm separates driving mechanism from coating liquid to avoid paint adhesion, achieving service life over 5 million cycles. Fully pneumatic structure without electric parts eliminates spark risks for explosion-proof coating workshops. Matched manifold base supports centralized control of up to 15 colors; optimized internal flow channel cuts thinner consumption during flushing and prevents cross-color contamination. Available for single standalone mounting or dense manifold stacking, widely applied in auto, furniture, hardware & home appliance automatic coating color change systems, solvent circulation cleaning and spray gun purge air circuits.

VSG-40.5C type Side installation Indoor high voltage vacuum circuit breaker used spring to storage energy. The operating mechanism can be operated by two ways, by manual and electromotive operation, The characteristics is according with GB1984-2003 High Voltage AC Circuit Breaker, JB3855-1996 3.6-4.5KV Indoor AC High Voltage AC Circuit Breaker and IEC standard 62271-100:200162271-100:2001 High Voltage AC Circuit Breaker VSG-40.5C series vacuum circuit breaker is a new type of three-phase 50Hz according to the unique design concept and combined with the market demand and development, the rated voltage of indoor switchgear 40.5kV, it can be provided to industrial and mining enterprises, power plant and substation as the control and protection of electrical equipment, and is suitable for frequent operation.

The VSG-12 indoor high-voltage vacuum circuit breaker is designed for use in indoor switchgear applications within 12kV power systems with a three-phase AC 50Hz rated voltage. It serves as a crucial protective and control unit for power distribution equipment and industrial facilities. This circuit breaker is suitable for environments that require frequent operations at the rated current or the capability to interrupt short-circuit currents multiple times. The circuit breaker features a modular design, where the operating mechanism and the circuit breaker body are separable, allowing for quick replacements and assembly. VSG vacuum circuit breaker is a new indoor switchgear. It is mainly used for three-phase AC power system with rated voltage of 12kV and rated frequency of 50-60HZ. It has the advantages of compact structure, high reliability, small operation vibration and easy maintenance. It can be widely used in power plants, steel mills, metallurgy, petrochemical, transportation, buildings and other industrial and mining enterprises. As a switchgear for protecting high-voltage motors, transformers, line faults and other loads.

SOLH TR twin shaft cylinder is manufactured in accordance with JIS industrial standards. It adopts a single-piston dual guide shaft structure matched with extended slide bearing bushes, featuring high structural rigidity, excellent torsion resistance and strong anti-deflection capacity superior to cost-effective TN twin shaft cylinders. Bore sizes range fully from φ6 to 32 mm, including standard single-rod TR, double through rod TRW and lightweight compact TRJ variants. Anti-rotation accuracy reaches ±0.1° for bores ≥16 mm and ±0.2° for φ6/φ10 small bores; dual shafts restrict swinging deviation to guarantee stable operation over long strokes. An adjustable front rubber cushion pad cooperates with fixed rear buffer for stroke trimming, impact absorption and noise reduction. Three-way mounting (top, bottom, side) and optional dual-side porting are available; side grooves allow direct assembly of magnetic switches without extra brackets. Built-in magnetic rings marked suffix S are standard, while non-magnetic customized versions are offered for magnetic interference sensitive occasions. Operating pressure ranges 0.15~1.0 MPa with working temperature from −20℃ to 70℃. Standard Rc thread can be converted to G thread or NPT thread for overseas engineering projects. Distinguished from CXS twin cylinders: TR outputs single thrust with prominent mechanical rigidity and stable side-load resistance in long-stroke applications; CXS features dual pistons for double thrust, lower friction and smoother high-speed reciprocation suited for high-frequency short-stroke pick-and-place. Widely applied in precision positioning, workpiece pressing, long-distance stopping & transfer and general automation stations requiring reliable guiding under medium-light loads.
