Worm Gear |
The precision worm and worm wheel mechanism
transfers
high torque with high efficiency and low sound level( Max.5
0d B) even though small in size.
Additional benefits include low backlash and longer life.
Various output torques(60Nm~2,500Nm) cater for valves from
2" to 24".

|
|
|
|
|
|
|
|
|
|
Standard enclosure with o-ring sealing is watertight to IECIP67,
NEMA4 and 6.The actuator is available with optional explosion
proof enclosure.
|
|
|
|
Electric wrring of control circuit is standardized for single
and three phase power supply in a single module. Multiple
terminal contacts sufficiently cover additional requirements
such as auxiliary contacrs for DCS, interlocking and other
options.
|
|
|
|
|
|
Mechanical and electrical module can be separated easily
to improve assembling, maintenance and alteraton of eletrical
requirements. Actuator has enough internal space for optional
accessories.
|
|
|
|
|
Size of handwheel is designed for safe and efficient emergency
manual operation.
|
|
|
|
Hand / auto declutching lever for handwheel engagement. The
power drive is automatically restored by motor start.
|
|
|
|
Base mounting is standard to ISO 5211. Drive bush is removable
for machining to valve stem requirement. The actuator position
on the valve can be selected for 4 positions by means of 4
bolt holes in the drive bush.
|
|
|
|
A space heater inside the actuator prevents condensation
due to temperature and weather changes. Standard 200W heater
keeps all electrical components in the actuator clean and
dry.
|
|
|
|
The limit switch is acticated by means of a simple and yet
reliable cam mechanism mounted and driven by the center column.
The valve position can be accurately and easily set with the
simple adjustable switch mechanism. The set position is permanent
and is not affected by over-travel resulting form manual operation.
|
|
|
|
Cam activated torque switches are easily adjustable to provide
over-load protection.
|
|
|
|
Rolled steel wormgear on aluminium bronze wormwheel self-locks
to prevent valve back drive on control signal or power failure.
|
|
|
|
|
|
|
|
|
|
|
Providing the dry contact signal
to check valve's positions (cam switches structure). |
|
|
|
Providing the dry contact signal
send to customer's panel as fault signal (cam switches
structure). |

Applicable Function
- |
Auto Scan-Automatically
memorized each open/close position by the
signal of PIU.(It is very easey to set the
PCU even in local area only requiring one
push of the Auto Scan button)
|
- |
Fail close-Drive to close
position there is no certain input signal
|
- |
Fail open-Drives to open
position there is no certain input signal
|
- |
Manual operation mode-Zero
Null/Span Open
|
- |
Operational Setting-It is
possible to fix a certain signal as Open
and Close.
|
- |
Manual Operating-Locally
move valve's position without source of
signal by direct use of dip switch on PCU
board
|
|
|
|
|
|
|
A small unit that is mounted to the actuator to operate the
valve's position in local. Local/Remote switch Open/Stop/Close
switches
|
|
Rugged structure with special parts (Explosion proof type
Selector, pushbutton switches) Guarantees that watertight
and safety working in hazardous environments.
|
|
|
|
