The ergonomically designed lever allows easy, precise operation. To protect against unintentional or unauthorized actuation, it is lockable as standard and functions with all-new accessory options. Even a tool for removing the union bush is integrated.
The 543 Pro is there for you in case you forget: A manual spring return unit ("dead man's lever") ensures that the valve closes automatically when released. This reliable, compact, and cost-effective solution ensures end-to-end process safety and easily eliminates potentially far-reaching risks.
The optional LED position feedback allows the current position of the valve to be centrally recorded and checked at any time – for manually operated and automated valves. The compact dual-sensor fits even in the tightest areas and is protected against the ingress of water and dust (protection class IP67).
The Data-Matrix-Code on the 543 Pro simplifies storing all technical information for each valve, thus enabling individual traceability. The faultless identification of each valve facilitates easy installation, service, and repair.
Pneumatic and electric actuators from GF Piping Systems help make processes more efficient and reduce maintenance costs. Where appropriate, they also contribute to digitization by making it easier to access process and component data and use it to optimize the system.
