ORION

Orion is an ISO 9001: 2015-certified company that manufactures small electrical switches such as industrial, pressure, and vacuum switches. Orion switches are great because of their high performance, durability, and small size.

Orion is a 44-year-old leading company that supplies a precision-designed range of compact electrical switches, electric vacuum switches, pressure switches, differential switches, and vacuum switches for use in hazardous and non-hazardous environments.

Our ability at PVL to work with and sell items to fit the needs of our customers has made Orion a preferred vendor with many renowned clients.

For their FC series flameproof/explosion-proof pressure switches, they became the first firm in India to get BASEEFA ATEX and IECEx certifications. Because of their capacity to design products from the bottom up, we have met our clients' ever-increasing demands.
