Product Advantages:

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;

Non-rotating lower stem operates linearly instead of helically, preventing damage to seat and tip components;

Reduces friction between packing and lower stem;

Seals maintain integrity without leakage at corresponding temperatures;

Achieves shut-off or regulating flow control by replacing the valve core;

Customizable full stem available upon request;

Seal material options: PTFE, PPL, graphite;

Optional valve panel mounting;

Handles available in multiple colors or with handwheels;

Each valve undergoes seal testing before shipment, with 5% of the units subjected to water pressure seal testing at 1.5 times the rated working pressure.
