Series ZB and series ZC electric valve actuators are used to
operate valves of which the clacks move linearly, such as globe
valve, gate valve, throttle valve, diaphragm valve etc. They
are suitable for rising-stem valves and non-rising-stem valves
as well. They are essential to carry out remote control, central
control and automatic control of valves. These actuators are
divided into ordinary type and outdoor type according to service
circumstances. They can also be divided into torque mode and
thrust mode according to output force. Motors fitted to actuators
are designed and manufactured by ourselves. They are characterized
by large starting torque and small inertia. .
series of electric valve actuators (Integrated actuators are the
abbreviation) are divided into Type ZB and Type ZC . They are
made up of actuator and electric control box and may be operated
alone. Owing to the built-in module blocks, resolution of phase
rule, protection of absent phase and operation control are provided.
These actuators are easy to install and of full functions. Output
torque of these actuators is from 50 to 10000N ¡¤m. These actuators
are provided with flameproof specifications and common specifications.
(Actuators with output torque from 3500-10000 N ¡¤m without flameproof
specifications). These actuators are suitable to valves of of
which the clacks move linearly, such as globe valve, gate valve,
throttle valve , diaphragm valve etc. They can be used for rising
stem valves and non-rising stem valves as well. They are necessary
devices to carry out remote control, centralized control and auto
control of valves.
