NS Square Bar Series Features:

1. Dual-stem design: The upper stem features threaded hardening, while the lower stem has a smooth surface hardening. The grease in the upper stem threads is isolated from the system medium.

2. Non-rotating lower stem operates linearly instead of helically, preventing damage to seat and tip components while reducing friction between packing and lower stem.

3. Select valve accessories based on pressure, temperature and media to ensure no leakage under specific operating conditions and prevent seal failure at corresponding temperatures.

4. Can achieve shut-off or regulating flow control by replacing the valve core.

5. Optional valve panel mounting

6. Handle available in multiple colors;
