Product Advantages:

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 with linear operation replaces helical motion, 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;

7. Each valve undergoes sealing tests before shipment, with 5% tested at 1.5 times rated working pressure.
