Product Description

The Soda Ash Chemical specilized semi-ball valve is a type of newly designed valve which is the upgrades and improvement of the common semi-ball valve to solve"liquid -gas"two phase medium scaling and corrosion problem, which is mainly used for cutting off,adjusting and changing the medium flow direction in the pipeline.With many years'rich experience on R&D, based on the introduction the technology of Germany CANALI semi-ball valve, Henan Quanshun accomany with the College of Materials Science and Engineering of Zhengzhou University developed the Soda Ash Chemical specialized semi-ball valve, at the same time the valve structure is optimized by the Lanzhou Unversity.The valve is very suitable for the application of bottom of Carbonation Tower, Inlet and Outlet of the Ammonia I and Ammonia II Pump,Inlet and Outlet of Mother Liquior I and Mother Liquor II pump, Connecting pipe of the carbonation tower,Second  Brine,Neutralized Water Adjustment and Cutting off position, and the product is now widely recognized and praised because of its small flow resistance and good sealing performance.
1.With straight through type valve body ,this valve can keep the medium flow by linear when the valve fully opened,so it reduced less energy loss compared with other valves.
2.Easy to operate: As the valve disc moved away from valve seat without any contact,so it has smaller starting torque compared with O type ball valve and easy to operate.
3.Because of double eccentric structure design ,the semi-ball valve is perfectly sealed and can be closed tightly .
4.When the valve is closed ,the wedding force is able to remove the foreign materials ,therefore it has anti-scaling performance.
