Modularity is the cornerstone of the entire VRC line. Upgrading or modifying any unit is simple, quick and hassel-free. Switch from pneumatic to electro-pneumatic with ease. Upgrade a positioner in the field with Limit Switches and position Transmitters easily. VRC simplifies upgrades, minimizes inventory and eases servicing like no other line on the market.
VRC corrosion resistance is unequaled. The I/P Converter and Position Feedback Transmitter are epoxy sealed and the Proximity Switches are hermetically sealed for the ultimate environmental protection. The PPA enclosure and internals exceed NEMA standards and are specifically designed for all routine and most highly corrosive applications. The PPA enclosure is inherently waterproof and carbon graphite filled to satisfy the toughest demands in both indoor and outdoor applications.
Adaptability is a key feature of the V Series. Regardless of actuator model or design, the option V Series Universal Mounting Kit allows for customized adaptation to most current industry models, sizes and styles of quarter turn actuators. The low profile design of the V Series Universal Mounting Kit insures high performance adaption to the accessory side of the actuator.
