PN16
TLV TC2 balanced self-acting single seat globe valve type temperature regulator. Suitable for steam heating of liquids, air and non-hazardous gases.
Features
- Self-acting design simplifies installation by eliminating the need for power supply and instrument signal lines.
- No external energy required, allowing for ease of installation in remote areas or potentially flammable atmospheres.
- Robust design minimizes maintenance.
- Reliable long-life spring mechanism protects the sensor from overheat damage.
- Wide set point range and simple set point adjustment provide easy operation.
- Pressure-balancing bellows provides improved flow and differential pressure performance compared to unbalanced type.
