SOLH 50 series flameproof pilot solenoid valves cover two models: 50-VFE 5/2 spool valve and 50-VPE 3/2 poppet valve. Certified Ex d Ⅱ BT4, CCC, TIIS & IEC with IPX6 protection, they apply to Zone 1 & Zone 2 flammable and explosive environments such as lithium coating, chemical, painting and oil & gas workshops. Both share interchangeable 3.5W low-power flameproof coils and housings, while their manifold bases are non-interchangeable. 50-VFE requires 0.15MPa differential pressure and only works for positive-pressure double-acting cylinder circuits, incompatible with vacuum. 50-VPE features zero-pressure startup, stable under full vacuum down to -101.2kPa and automatic pressure relief upon power loss for vacuum handling and single-acting cylinders. Lubrication-free design allows single threaded mounting or multi-station manifold valve island assembly with certified flameproof wiring fittings, providing safe standard pneumatic switching for explosion-proof industrial production lines.

Guide rail for electrical switchgear is a mechanical structure for supporting, guiding and mounting switchgear components, mainly used in electrical equipment. The core goal of its design is to ensure the stability of the switchgear, accurate alignment and ease of subsequent maintenance and replacement. Rails are usually made of aluminum alloy or galvanized steel, with strong load carrying capacity and corrosion resistance. For special environments (such as wet or corrosive places), the rails will be made of anti-corrosion treatment or stainless steel. Common rail shapes include "C", "U" or "L" sections, designed to be compatible with many types of switchgear. In addition, the standard size of the guide rail conforms to international specifications, which facilitates the modular installation of the equipment. In order to cope with the harsh environment, the surface of the guide rail may be galvanized, electrophoretic coating and other treatments to improve corrosion resistance.

The switchgear spring component is a crucial part of electrical switchgear systems, designed to provide the necessary force and stability for the operation of various mechanisms within the switchgear. These springs are typically made from high-quality stainless steel or other durable, corrosion-resistant materials to ensure longevity and reliable performance under various electrical load conditions. The precision engineering of these springs allows them to withstand high-stress environments, making them suitable for both medium and high-voltage switchgear. Available in various sizes and tension ratings, the switchgear spring component is customizable to fit specific equipment requirements and operational demands.

Low Voltage Switchgear Cabinet Drawer handle is an important component of low-voltage switchgear or electrical chassis. The handle is designed to facilitate smooth and safe operation of the drawer compartment. The drawer handle is designed not only for ease of use, but also for safety and durability, which can be stable for a long time in frequent operation. Drawer handles manufactured by Ruziger are made of corrosion-resistant, age-resistant materials for a long service life.
