China Switchgear Interlocking Components Manufacturer, Supplier, Factory

SOLH 4F pneumatic foot pedal valve adopts integrated die-cast aluminum housing and is fully interchangeable with AirTAC equivalent models. Built on self-developed dual-exhaust sealing technology, it is mass-produced on automated assembly lines with sufficient spot inventory and steady global shipments. Available in self-reset, self-locking and safety guard versions with IP54 dust & splash resistance, it controls reciprocation of double-acting cylinders widely for stamping, riveting fixtures and on-site circuit debugging. High airflow delivers quick response, impact-resistant structure fits heavy-duty frequent stepping in industrial workshops.

Richge is a manufacturer of High Voltage Insulation Contact Sleeves in China, specializing in producing top-quality sleeves designed to provide superior insulation and protection for high-voltage electrical contacts. Our insulation contact sleeves are engineered to ensure safety, reliability, and optimal performance in high-voltage applications.

SOLH CRB1 / CRB2 vane-type rotary actuators are fully interchangeable with equivalent SMC swing cylinders. Direct vane drive eliminates gear backlash, delivering low rotary inertia and ultra-fast response. CRB2 is the compact light-duty range with bore sizes 10~40 mm; single vane supports up to 270° swing while double vane limits rotation to 90°/100°, ideal for high-speed mini flipping in confined-space 3C and packaging equipment. CRB1 heavy-duty series covers 50~100 mm bores with full bearing support and outstanding impact resistance, providing maximum torque up to 24 N·m for heavy fixture and large workpiece indexing turnover. Single vane offers wide swing range, whereas double vane doubles torque at the same bore size. Built-in rubber bumpers come standard; angle adjuster suffix Z and hollow shaft are optional, and CDRB variants integrate permanent magnets compatible with D-M9B / D-A93 reed switches. Compared with MSQ rack-and-pinion rotary tables, vane-type cylinders feature slimmer body and faster rotation with zero backlash yet weaker radial & axial load capacity, making them the top choice for high-speed light-load rotary tasks requiring large swing angles.

SOLH MBB lightweight tie rod standard cylinder is an upgraded lightweight model, 10% lighter than traditional MB series and fully compliant with ISO15552 standards for direct replacement of imported tie rod cylinders. Featuring double-end adjustable air cushion and square end caps, it ensures high rigidity, low noise and stable oil-free operation, suitable for medium-load and high-frequency working conditions. It covers multiple variants and diverse mounting options, widely used in conveying equipment and general automation machinery. With mature mass production and sufficient stock, it supports stable batch supply and exports worldwide.

SOLH 2W series 2/2-way normally closed fluid solenoid valve with solid brass body includes small orifice direct-acting 030/050 models and large bore pilot-operated 150~500 variants, designed for automatic on-off control of clean water, compressed air, cutting coolant, lubricating oil and weakly corrosive fluid pipelines. The direct-acting version realizes zero differential pressure startup with no minimum working pressure limit, features compact size, universal mounting orientation and millisecond high-frequency switching, ideal for low-pressure micro-flow branches, vacuum auxiliary water circuits and single-point cooling for small machine tools. The pilot-operated type requires a minimum 0.05MPa startup differential pressure, delivers ultra-large flow with low-power low-temperature-rise coils, suited for air compressor main drain lines, general assembly main spray water circuits and high-flow circulating pipelines for water treatment systems. Standard NBR nitrile rubber seals are equipped, with optional heat & acid resistant EPDM food-grade seals. Multiple international thread standards (PT/G/NPT) and full-range coil voltages (DC12/24V, AC24/110/220V) are available, supported by DIN plug sockets for cabinet wiring and IP65 waterproof wire leads for humid outdoor equipment. Heat-resistant coils allow 24-hour continuous energization without burnout. Selection guidelines: choose direct-acting type for pipelines with static pressure below 0.05MPa and micro single-point flow; select pilot-operated variant for G1/2 and above main headers with stable high-pressure large circulation. EPDM seal is mandatory for hot water, purified water and food-grade fluid media.
