The High-Voltage AC Switch for Grounding is a vital safety device in high-voltage power systems, designed to facilitate the grounding and isolation of electrical equipment during maintenance operations. It operates effectively at voltage levels between 12kV and 40.5kV, showcasing robust short-circuit withstand capabilities and reliable mechanical functionality. With its compact design, it ensures straightforward installation and user-friendly operation, making it suitable for high-voltage switchgear and substations. Compliant with rigorous international standards, this grounding switch provides consistent safety and performance in demanding electrical conditions.

SOLH MAL lightweight aluminum alloy mini pneumatic cylinders are ultra-economical compact actuators designed for light-duty automated applications. Constructed with hard-anodized aluminum barrel and end caps paired with anti-rust stainless steel piston rod, this model is 15% lighter and around 10mm shorter in overall length compared with conventional MA series cylinders while greatly cutting procurement costs. It features excellent dimensional interchangeability with MA and CM2 cylinders for straightforward replacement and low-cost equipment retrofits. Adopting dual-end thread locking assembly ensures stable structural performance during continuous operation; the streamlined round body allows easy disassembly, inspection and maintenance. A full portfolio of variants covers standard double-acting, spring single-acting power-off reset types, synchronous double-rod units and stroke-adjustable MALJ versions to meet diverse light-load linear motion requirements. Standard rubber bumpers absorb mild shock and noise, with optional adjustable air cushions available for high-speed frequent cycling. Low-friction composite sealing with built-in oil storage grooves supports oil-free maintenance-free operation with a service life reaching 5 million cycles. An optional built-in magnetic ring works seamlessly with SMC M9B and Airtac CS1-G magnetic sensors to achieve real-time piston position feedback and PLC automatic linkage control. Supported by stable mass production and fast order fulfillment, these budget-friendly cylinders are widely applied in electronics assembly, packaging machinery and light industrial automation under dry and low-dust working environments.

SOLIH AW series integrated filter‑regulator combines 5μm air filtration and overflow‑type pressure regulation in a one‑piece unit. Max 1.0 MPa, adjustable 0.05–0.85 MPa, manual/auto drain options, pull‑to‑adjust push‑to‑lock knob, transparent PC bowl with protective cover, built‑in gauge port. Models AW2000–AW5000 with Rc1/4"‑1" ports, ideal space‑saving replacement for AF+AR combo, splicable with AL lubricator for full FRL assembly.

The Electrical Panel Indicator is a vital component in industrial and commercial electrical panels, designed to provide clear, real-time visual indications of operational status. Constructed from high-quality, durable materials, this indicator is built to withstand harsh environmental conditions and ensure long-term reliability.

SOLH MK six-surface mount compact cylinder is upgraded from MD cylinder with built-in anti-rotation mechanism. The piston rod anti-twist accuracy reaches ≤±0.5°, directly interchangeable with Airtac MD and SMC CQS series. Square thin body allows bracket-free installation on six sides and facilitates compact parallel layout of multiple cylinders. Variants include double acting MK, single acting MSK/MTK, MKD double rod and MKJ adjustable stroke models. Built-in magnetic ring optional with rubber end buffers and oil-free capability. Bore sizes φ6~32mm, widely applied in 3C precision tooling and short-stroke clamping positioning for automation requiring fixed workpiece angle in confined space.

SOLH VH series 4-way 90° manual rotary hand valve switches air circuits by rotating handle, with three optional center functions: 3-position center closed, 3-position center exhaust and 2-position type. Adopting precision rotary spool seal for ultra-low internal leakage, it features zinc alloy / die-cast aluminum body and lubrication-free long service life, with built-in mechanical position lock to avoid accidental operation. It supports side port and bottom port piping layout, available for panel flush mounting or direct body fixing, with port sizes from Rc1/4" to 1" and max operating pressure 0.7~1.0MPa. Center closed version keeps cylinder clamping pressure during shutdown, while center exhaust fully releases pressure for safe maintenance. Widely used for manual cylinder reversing, equipment commissioning venting, emergency air source isolation, semi-automatic machine manual operation and pneumatic teaching test benches.
