SOLH SI series tie-rod-free profile pneumatic cylinders strictly comply with ISO 15552 (formerly ISO 6431) and VDMA 24562 international standards, perfectly interchangeable with Festo DNC, SE and DSBA series cylinders as a cost-effective mid-tier alternative. Constructed with an integrated star-shaped square aluminum alloy profile without exposed tie rods, the cylinder body delivers superior structural rigidity, outstanding anti-torsion and anti-deflection performance alongside a tidy, corrosion-resistant exterior ideal for neat side-by-side arrangement on automated lines. Built-in dedicated sensor grooves on both sides support direct installation of AirTAC CMSE, DMSE and CS1 magnetic switches without extra mounting brackets. Equipped with standard dual-side manually adjustable air cushions paired with PPV elastic bumpers, it effectively cushions inertial impact and suppresses noise during high-speed heavy-duty reciprocation. The premium dual Y-type compensation sealing system ensures an ultra-low starting pressure of 0.1 MPa and stable long-term oil-free operation. Its hard chrome-plated 45# steel piston rod boasts excellent wear and rust resistance. A complete lineup of customized variants covers SID double synchronous rod, SIJ stroke-adjustable model, SIL position-locking version, SIF valve-cylinder integrated actuator and SIQ anti-torsion square piston rod type to satisfy diverse industrial requirements. The whole series is pre-fitted with a built-in magnetic ring by default for real-time piston position feedback and PLC linkage control. Widely adopted in European-standard export machinery, automated assembly, packaging, material handling and machine tool auxiliary drive, it balances reliable performance and competitive pricing to replace conventional tie-rod SC cylinders and high-priced imported DNC cylinders.

The ZN12-24 vacuum circuit breaker is an indoor high-voltage switchgear with a rated voltage of 24kV and three-phase AC 50Hz.which introduced the technology from German company， Its operating mechanism is a spring energy storage type, which can be operated by AC or DC, or manually. This circuit breaker is a reinforced insulation type, which meets the requirements of the use environment in Class II polluted areas. This circuit breaker has simple structure, strong breaking capacity, long life, complete operation functions, no explosion hazard, simple maintenance, suitable for control or protection switch of power plant, substation and other transmission and distribution systems, especially suitable for breaking important loads and frequently operated places. This product is in accordance with related requirement of GB1984, JB3855, DL403 and IEC standards.

Richge is a manufacturer of HV insulation conduit 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.

SOLH VT317 direct acting 3-port poppet solenoid valve adopts elastic sealing structure with zero-pressure startup, working stably under 0–0.9MPa positive pressure and full vacuum down to -101.2kPa. Six switchable functions are integrated into one compact valve with high flow capacity, featuring ≤30ms response time and maximum 10Hz switching frequency. Lubrication-free elastic seals ensure reliable tightness and low maintenance cost. Equipped with standard non-locking manual override, it supports single piping or manifold valve island mounting with Rc1/4 port thread and dust-proof housing. It is widely applied in robotic arms, vacuum suction, air blowing, packaging, printing, woodworking and food automation equipment for general pneumatic on-off control.

SOLH MSZ three-position rack-and-pinion pneumatic rotary cylinders are dedicated rotary actuators engineered to achieve three-point locking positioning (left limit / intermediate stop / right limit), solving the limitation of conventional two-position rotary cylinders lacking mid-station positioning. This series only needs one 5/3-way center-pressure solenoid valve for full position switching, removing complicated dual-valve pneumatic circuits to simplify system layout and lower overall engineering costs. The intermediate locking position supports ±10° fine angular adjustment, while the left and right travel limits are separately tunable within 0~95°, delivering flexible multi-angle positioning. It is classified into four specifications: basic MSZB, high-precision MSZA, rubber buffer MSZB-R and hydraulic buffer MSZA-R. The dual-rack dual-piston internal structure effectively eliminates gear backlash and outputs steady torque during frequent position switching. The integrated rotary plate comes with reserved locating pin holes for direct workpiece installation, paired with a central hollow through-hole to pass wiring and air tubing neatly. Standard side sensor grooves fit D-M9B & D-A93 magnetic switches to realize real-time signal feedback of three working stations. MSZA boasts positioning accuracy up to ±0.02 mm, while hydraulic buffer variants absorb large collision energy perfectly for high-speed heavy-duty rotation. Adopting oil-free self-lubricating design for long-term stable running, this rotary cylinder is widely deployed in workpiece sorting diversion, multi-station indexing, electronic positioning inspection and packaging automated steering flip procedures.
