Explosion-Proof Linear Exb (C) L010~250 Series Linear Actuator
Explosion-proof linear EXB(C)L010~250 serires linear actuator
Feature: PLANETARY GEAR DESIGN The electric actuators of planetary gear have manual/electric auto-switching function & without clutch which ensures the safety of the operator.
A KEY SETTING(MODULATING TYPE) After installing the valve, the travel can be set by "A key setting", then the feedback signal can be revised automatically and enter the running state.
SELF-LOCKING PROTECTION Nut and shaft can lock itself mechanically.
HEATER Heater keeps the housing dry which protects the components.
LUBRICATION The actuators operate stable without maintenance by using low temperature grease.
DISC SPRING STRUCTURE Equipped with disc spring structure, which have a certain pre-tightening force which ensures the valve can be fully closed for a long time.
CHARACTERISTICS With the high efficiency of transmission device, thus cools down the temperature. Therefore, it's a lot safer to work in explosion-prone conditions.
