Extended Bonnet Cryogenic Globe Valve

Detailed Description:

UNICENTS Globe valves are used for throttling and frequent operation. Globe valve\'s structure is more simple than gate valve\'s, and it is more convenient in manufacturing and maintenance. The stem axis and the seat sealing surface is vertical, and it is a very reliable valve to cut off and control. Sealing surface is not easy to wear and scratch, and it has a good sealing surface and long service life. When opening and closing, disc\'s route is small, so the height of globe valve is smaller than gate valve, but the length of structure is longer than gate valve\'s.
