SOLH VP series CE certified pilot large-size 3-port solenoid valve features ultra-high flow with port sizes from Rc 3/8" to 1-1/2" and max Cv up to 7.0. Three grades of energy-saving coils (1.55W/0.55W/0.4W) are optional, with switchable NC/NO function without pipe modification, supporting 0~1.0MPa positive pressure and -101.2kPa vacuum conditions. Equipped with ozone-resistant HNBR main seals, FKM pilot seals and built-in dust filter, it allows arbitrary mounting and delivers a 50-million-cycle service life. Perfectly matched with VBA boosters and VBAT air tanks, it also fits heavy cylinders, vacuum fixtures, electrical cabinets, automotive & packaging machinery. Certified with CE, ASME, GB and ISO9001, it is an ideal heavy-duty switching valve for industrial pneumatic boosting and automation systems.

The Ground Knife Controller Switchgear is an essential device designed to manage the movement and positioning of switchgear units along guide rails in electrical systems. This controller ensures smooth and efficient operation, facilitating the safe installation and maintenance of switchgear equipment.

Product Details and Application of Switchgear PE Cable Deflector The Switchgear PE Cable Deflector is an essential component designed to protect and guide electrical cables within switchgear assemblies. Constructed from high-quality polyethylene (PE), this deflector offers exceptional durability and resistance to environmental factors, such as moisture and UV radiation. Its lightweight yet robust structure ensures reliable performance, reducing the risk of cable damage and maintaining optimal operational efficiency.

The Vertical Busbar Support is a critical component in electrical switchgear systems, specifically designed to provide robust and reliable support for vertical busbars. Constructed from high-strength, insulating materials such as fiberglass-reinforced polyester or epoxy, these supports ensure optimal electrical insulation and mechanical stability. They are engineered to withstand high mechanical stress and thermal expansion, maintaining the busbars' alignment and preventing sagging or misalignment that could lead to electrical faults.

Auxiliary Contact Switch The Auxiliary Contact Switch is a switch used in electrical equipment to extend the signal transmission function, assisting in the condition detection of main circuit equipment and providing additional switching signals during signal transmission. It acts as an auxiliary device to the main switch, providing additional contact signals to meet complex electrical control and indication requirements. Used to feedback, control, protect or indicate the status of a system, especially in automation and monitoring systems, plays a vital role. The auxiliary switch consists of a set of normally open (NO) and normally closed (NC) contacts that are synchronized with the state of the main switchgear. When the main device is operating, the contact of the auxiliary switch will be opened or closed according to the operating state of the device, thereby transmitting the signal to the control system or indicating device.
