1. Superior Stability & Anti-Vibration Performance

• Dual-Snap® patented disc spring technology eliminates contact chatter.

• Withstands 40 G's vibration and 250 G's shock → ideal for engines, compressors, heavy-duty vehicles, and offshore applications.

• No false trips due to pressure pulsation or mechanical vibration.

2. High Accuracy & Long Life

• Excellent set point repeatability (typically ±2%).

• Mechanical life up to 500,000 cycles or more, reducing maintenance costs.

• High system pressure rating up to 25,000 psi.

• Wide operating temperature range: -65°F to +450°F (-54°C to +232°C).

3. Rugged & Flexible Design

• NEMA 4 / IP65 enclosure → weatherproof and dust-tight.

• Field adjustable set point for convenient on-site calibration.

• Multiple configurations: pressure (604G/P), differential pressure (604D), and vacuum (604V).

4. Reliable Switching Action

• Snap-action mechanism ensures a clean, crisp switch response without erratic on-off cycling.

• Ideal for critical control, alarm, and shutdown logic in industrial environments.

Typical Applications

• Hydraulic & pneumatic systems

• Power generation

• Petrochemical

• Locomotive and rail equipment

• Water treatment
