Ball Valve 543 Pro is a 3-way valve designed for mixing, redirecting, distributing, or shutting off flow in chemical process and water treatment systems. Upgrades include a reinforced stem break point, double stem seals, lockable lever, integrated removal tool, and optional LED position feedback. Modular design supports manual, pneumatic, or electric actuation.

Performance

Optional LED position feedback with IP67 water and dust protection

Options and variations

Manual, pneumatic, or electric actuation; accessory options for feedback and safety

User-friendly operation

The ergonomically-designed lever allows easy, precise operation. To protect against unintentional or unauthorised actuation, it is lockable as standard and functions with all-new accessory options. A tool for removing the union bush is integrated.

Safety through dead man's lever

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.

Monitoring by the double sensor

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).

Information via Data-Matrix-Code

The Data-Matrix-Code on the 543 Pro simplifies storing all technical information for each valve, enabling individual traceability. The faultless identification of each valve facilitates easy installation, service and repair.

Driven to maximum performance

Pneumatic and electric actuators from GF Piping Systems help make processes more efficient and reduce maintenance costs. Where appropriate, they also contribute to digitisation by making it easier to access process and component data and use it to optimise the system.
