Forged Steel Plug Valve(Lined Plug Valve)
This valve lined with fluoroplastic,matched with novel structure within the large pressure difference and temperature variation range.This product can be acted as switchor adjustment to carry the liquids and gas (including the vapor) in various industrial pipes with strong corrosion such as acid, alkaline and salt.
Actuator:Hand actuator/Wormgear actuator/Electric actuator/Pneumatic actuator
