SOLH HRQ dual piston rack & pinion rotary cylinder includes micro sizes HRQ2/3/7 and medium-to-large HRQ10~HRQ200 with infinitely adjustable swing angle 0~190°. It outputs higher torque and stronger bending/radial load capacity than vane rotary actuators. Three configurations are available: basic mechanical stop buffer (low-cost for light low-speed duty), -A integrated hydraulic shock absorber (high-speed heavy load precise stopping), and -A(S) hydraulic version with stainless steel end caps for humid & slightly corrosive environments. The rotary table features central hollow through hole for tubing and wiring, and side sensor slots compatible with universal magnetic reed switches. Micro models adopt bottom mounting holes while medium/large sizes provide multi-side mounting taps for flexible layout. Pre-filled long-life grease enables lubrication-free operation. Selection requires simultaneous verification of torque, radial/axial load and bending moment. Widely used for rotary indexing in automatic assembly, material sorting, packaging capping and jig turnover stations.

SOLH VO307 manifold-mount 3-port direct acting poppet solenoid valve is tailor-made for valve islands and matched with VV307 series manifold bases. Without side pipe ports, it allows dense side-by-side arrangement to cut leakage points and save space. It supports zero-pressure startup, stable operation under 0–0.7MPa positive pressure and full vacuum down to -101.2kPa. Multiple modes including NC, NO, flow divider and selector can be switched by replacing cover plates. Adopting lubrication-free HNBR elastic seals, it achieves ≤20ms response time and 10Hz max frequency with standard manual override and low-power coils. Equipped with imported core parts for high cost performance, it is widely applied in robotic arms, vacuum suction, air blowing, packaging, printing and modular centralized pneumatic control systems.

Richge is a manufacturer of High Voltage Wall Bushings in China, specializing in producing high-quality bushings designed to facilitate safe and efficient transitions of high-voltage conductors through walls and barriers. Our wall bushings are engineered to ensure reliable electrical insulation and protection in demanding high-voltage applications.

Vertical Bus Switchgear Assembly The vertical busbar bracket is an important component in the switchgear assembly. It is made of epoxy resin, a common insulating material, which has excellent electrical insulation properties, durability and resistance to moisture and temperature changes. The vertical busbar bracket produced by Reziger can be flexibly configured according to different power requirements and application scenarios to meet the individual needs of users. The function is to fix the vertical busbar (a conductive metal rod carrying current) in the switchgear chassis to ensure that the busbar is correctly aligned and insulated from the surrounding environment to ensure that the current will not be damaged or overheated.

Vacuum circuit breaker is the most commonly used type of high-voltage circuit breaker, mainly divided into two kinds of indoor and outdoor. We mainly focus on indoor vacuum circuit breakers. (Indoor circuit breakers: High-voltage circuit breakers that do not have the performance of protection against wind, rain, snow, ice and dense frost, etc. and are suitable for installation and use inside buildings.) The vacuum circuit breaker is named after its interrupting medium and the insulating medium of the contact gap after interrupting is high vacuum; it has the advantages of small size, light weight, suitable for frequent operation and interrupting without maintenance, and is more popularly used in the 3kV-40.5kV distribution network. The components of vacuum circuit breaker are vacuum interrupter, electromagnetic or spring-operated mechanism, bracket and other parts. Vacuum interrupter is the core component of vacuum circuit breaker, its main role is, through the excellent insulation of the vacuum inside the tube to make the medium and high voltage circuit cut off the power can quickly extinguish the arc and suppress the current to avoid accidents and accidents.

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.
