China Switchgear Spindle Nut Manufacturer, Supplier, Factory

SOLH CM3 short stainless steel mini cylinders are upgraded compact replacements for traditional CM2 series pneumatic actuators. Constructed entirely from 304 stainless steel, they deliver outstanding rust and weak acid-alkali corrosion resistance suitable for food, pharmaceutical and clean workshop environments. Optimized structure shortens overall length by up to 29mm and cuts weight by 21%, paired with four-directional air ports to enable flexible multi-angle installation in narrow equipment space. Multiple variants including double-acting, spring single-acting, double-rod and anti-rotation piston rod meet diverse linear drive requirements; CDM3 magnetic version supports magnetic switch sensing for PLC automatic interlock control. Low-friction oil-free sealing ensures over 8 million stable operating cycles. Our factory maintains mass production and sufficient spot inventory, widely applied in medical packaging, electronic assembly and food processing automated positioning.

SOLH 3A series 3/2-way externally air-operated directional control valves are manufactured in accordance with mainstream industry standards. Driven entirely by pneumatic signal input without any electromagnetic coils, this series is engineered to govern extension, retraction and pressure retention of single-acting pneumatic cylinders. It serves as the critical safety control element for all-electric-free pneumatic circuits, hazardous explosive atmospheres and fail-safe industrial machinery. The standard three-port layout follows universal industrial definitions: P for main compressed air supply inlet, A for working outlet connected directly to single-acting cylinders, and R for exhaust port for pressure relief and rapid spring reset. Two control configurations are available. Single pneumatic control models (3A×10) switch upon receiving external air signals and automatically reset via built-in springs once the control air signal is removed to guarantee fail-safe reset performance. Double pneumatic control variants (3A×20) adopt latching spool structure, locking the valve position persistently even after control air is disconnected to sustain long-term clamping and positioning. Constructed with high-strength aluminum alloy valve bodies and precision-machined spools, the valves support oil-free operation under filtered compressed air with filtration precision above 40 μm within the working pressure range of 0.15~0.8 MPa. Four dimensional specifications from miniature 3A100 up to heavy-duty high-flow 3A400 cover M5 to G1/2 thread connections, and NPT threads are optional for overseas projects. Without internal electrical parts, the valve features intrinsic explosion-proof performance, perfectly suited for flammable, dusty and humid working environments. It supports random multi-angle installation and manifold assembly for modular valve banks, widely deployed in workpiece clamping mechanisms, pneumatic safety interlock systems and long-duration positioning stations.

SOLIH ZL1 series multi stage energy saving vacuum ejector, fully interchangeable with SMC ZL1. Max suction flow 100 L/min (ANR) at 0.4-0.6 MPa supply. Valveless or integrated with valve versions with supply/release valve combinations (K1/K2/B1/B2), optional vacuum pressure switch (NPN/PNP, analog output), indicator-surge protection circuits. Ideal for robot EOAT, 3C pick and place, lithium battery and porous material handling automation.

The Horizontal Busbar Support is a crucial component in electrical switchgear systems, designed to securely hold and support busbars in a horizontal configuration. Crafted from high-strength, non-conductive materials such as glass-reinforced polyester or other engineered polymers, this support provides robust mechanical strength while ensuring electrical insulation. Its design often incorporates multiple channels or grooves to accommodate various busbar sizes, ensuring flexibility in application. The surface is typically treated to resist environmental factors such as moisture, chemicals, and UV radiation, making it suitable for use in both indoor and outdoor installations.

The switchgear guide rail system controller is a crucial component designed to facilitate the smooth operation of switchgear systems along guide rails. This controller enables precise control of the movement and positioning of switchgear units, ensuring efficient installation, maintenance, and operation.

SOLH HSV series 3/2-way hand slide pneumatic valves adopt an inline sleeve push-pull integrated structure, fully consistent with the dimensional specifications of mainstream AirTAC HSV series and interchangeable with equivalent domestic counterparts. Designed without return springs and equipped with mechanical self-locking positioning, this valve switches airflow by axial pushing and pulling: pushing the sleeve forward connects the P inlet port and A working port for normal air supply; pulling backward disconnects the air intake and automatically links port A with the built-in R exhaust port to rapidly vent residual pressure inside rear pipelines and actuators. It serves as a dedicated safety shut-off switch for pneumatic branch pipelines and essential pressure relief valve for equipment maintenance work. Three standard ports are configured: P for main compressed air inlet, A for output to downstream pneumatic components, and an embedded built-in R exhaust port hidden inside the valve body. A wealth of specifications covering G1/8 up to G1 thread sizes are supplied, paired with three thread layout options (SF single inner & single outer thread, SS double outer threads, FF double inner threads); PT taper thread, G parallel thread and NPT thread are selectable to fit global piping standards. Constructed with hard-anodized aluminum alloy valve bodies, stainless steel anti-rust spools and high-performance NBR nitrile rubber sealing rings, the valve supports lubrication-free operation under filtered compressed air within 0~1.0 MPa rated working pressure and withstands test pressure up to 1.5 MPa. The operating push-pull force is controlled at 18~25 N for smooth operation, and the mechanical locking structure maintains the set position firmly without drifting or air leakage caused by accidental touching. Different from 4HV rotary hand valves used for forward/backward switching of double-acting cylinders, the HSV series is engineered exclusively for pipeline on-off and pressure release. It can be directly installed in series within air pipelines without extra mounting bases to save installation space. Widely deployed for isolating air supply before equipment overhaul, main air circuit safety cut-off of automation tooling, vacuum pipeline switching and branch circuit independent air source control, it effectively eliminates hidden dangers brought by residual pressure during maintenance and guarantees on-site operational safety.
