Cryogenic Ball Valve

Cryogenic ball valve is designed for low temperature and other cryogenic application. The valves have the structure of integral bonnet extension which prevents cryogenic liquids from reaching the stem packing by enabling the liquids to boil and convert to gas. This minimizes the energy loss along the extension and protects the valve from malfunctioning.

Product Description

1.What are the cryogenic ball valve

Cryogenic ball valve is designed for low temperature and other cryogenic application. The valves have the structure of integral bonnet extension which prevents cryogenic liquids from reaching the stem packing by enabling the liquids to boil and convert to gas. This minimizes the energy loss along the extension and protects the valve from malfunctioning.

2.What are the features of cryogenic ball valve

1. Extended stem and bonnet to position the stem packing above the cryogenic fluid and providing a column of warmer vapor that insulates the stem seal from the affects of low temperatures.
2. High-density seats and seals throughout valve enables the valve to be rated down to -260ºF (-162°C) service.
3. Valve is unidirectional with vent holes in both the stem slot and the upstream face of the ball. This prevents the cold liquids from becoming trapped in the valve.

4. Each valve is permanently marked with a flow direction arrow to prevent incorrect installation.
