Stainless Steel API Gate Valves

CHAODA Valves Group is specialized in manufacturing API Stainless Steel Gate Valve with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc.

   API Stainless Steel gate valve is a valve realizing the closing and opening function by lifting the disc up&down as the closure member. The main advantages of API Stainless Steel Gate valve are smooth flowing passage, small flowing resistance and small operation torque, while the main disadvantages of this valve are: easy-damaged sealing face, long closing&opening time, large volume&weight. Gate valve is widely used on pipeline as it's suitable to be manufactured with big size. Gate valve is and generally for cutting off purpose but not intended to be used as a regulating valve because the sealing face would be corroded by the medium easily when valve is not in fully open or closed position.

API Stainless Steel Gate Valve product description

   API Stainless Steel Gate valves(Generally flanged connection, but Butt-welding optional) are suitable for use on various kinds of pipeline from Class150 To Class300, DN15 To DN600 to cut off or connect the flowing of medium. By using different material, the API Stainless Steel Gate Valve could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/bevel gear/pneumatic or electric actuators could be chosen by needs. 

   The combination of flexible & braided graphite structure ensures the API Stainless Steel Gate valve has the necessary strength while achieving good sealing. Split gland flange and gland structure with a spherical touching surface ensures no scratch occurs to stem when working. The run-out of stem thread is always above the packing to prevent taking out of packing when stem moves. There is no external leakage of this kind of packing box which also meet the environmental requirement.
