Rising Resilient Seat Gate Valve
Purpose
The electric actuated resilient seat gate valve can be fitted with various electric executors (domestic, imported, various levels of protection and anti—explosion) in accordance with the user’s requirement, can be on-site operated and remotely controlled, as well as electric and hand operated. Usually fitted with a domestic executor, if there is no special requirement from users. Please make a note at order, when an electric control box is needed. Except the electric executor, all the other parts with the electric actuated resilient seat gate valve are identical to those with the inside screw non-rising stem type.
