PTFE Butterfly Valve
PTFE Butterfly Valve
Technical Parameter
1)Nominal Diameter: DN40-DN150
2)Design standard: GB/T 12238-1989
3)Face to face: GB/T 12221-2005/ISO 5752-1988
4) Flange dimension: GB/T 9113-2000/ISO 7005.2
5) Inspection standard: GB/T13927-92
Main parts
a) Top flange as per ISO5211 standard can suit for all kinds of acuators such as handkes, gear box, electric actuator and pneumatic actuators
b) Stem Round with key, square and double "D" for your selection.
c) O ring prevent stem from leakage
d) Shaft seal : bounding of elastomer to phenolic backing ring protect from distortion, a common cause of shaft leakage.
e) Precision profile disc provides bubble-tight shut-off and assures minimum torque value and long seallift
f) The edge-boot seat features lower to torque and eliminates the need for flange gasket, the way of edge-boot seat with valve body makes field replacement simple and fast.
