Valve actuator Products CatalogElectric actuator (Nippon Gear)
Multi-turn type
-
🆕LSB series
The LSB series is a electric actuator with a compact and light body.
This is a state-of-the-art mechanical actuator in the world. -
AE series
Smart-type electric valve actuators enable diversified control by digitalizing torque detection and position detection.
-
JX-05M series
Super small valve actuators have been developed for small-diameter glove and gate valves.
Special motor (Option)
-
Motor for nuclear power (in a containment vessel)
The motor has a special design, such as heat-resistant wiring material, and parts with special specifications.
-
AC motor for hydraulic gate (General-purpose characteristics)
The mode is compliant with hydraulic gate and penstock standards.
-
DC motor
The motor is compatible with DC power supply.
-
Single-phase AC motor
Single-phase AC motors can also be attached.
-
Air motor
The motor is powered by air pressure.
-
Tandem motor
The electric AC motor is equipped with an air motor at its rear section.
Communication and control
-
G-LINK communication control system
A digital communication system that provides centralized control for actuators.
-
PROFIBUS-DP
A type of open field bus, which is the most popular field bus in the word today.
-
Hard wire type remote control system
A system that connects and controls the actuator and central unit one-on-one.
Part-turn type
Electric actuator (Limitorque)
Multi-turn type
-
SMB series
Valve actuators with many achievements in the fields of basic industries, such as thermal and nuclear power plants.
-
L120 series
Actuators made by reducing the size and weight of SMB-type actuators. The housing is made of die-cast aluminum to save weight.
-
JMB series
Valve actuators, based on the SMB series of valve actuators, which have many achievements, are equipped with an interlocking switch that shuts off electric currents when operated manually.
Manual actuator (Nippon Gear)
Multi-turn type
-
BGA series
Bevel gear-type actuators can be attached directly to the gate and glove valves to receive thrust so that they can be opened/closed easily by hand.
-
PA series
Spur gear type actuators can be attached directly to the gate and glove valves to receive thrust so that they can be opened/closed by hand.
Part-turn type
-
CWG series
Very compact worm gear reducers are for general industry, such as water supply and sewerage systems, and iron and steel were developed as manual operation devices for various kinds of devices, such as valves for 90-degree rotation, including butterfly valves and ball valves.
-
MLT series
Reducers for butterfly valves have a built-in sub-valve using a relay reduction gear.
Manual actuator (Limitorque)
Multi-turn type
Part-turn type
Option
-
Environmentally-resistant specification
We offer options that can be used in a wide variety of environments, such as water-resistant, sulfur-resistant, fire-resistant, and cold-resistant conditions.
-
Introduction of electric components
We offer a lineup of various types of electric components to effectively deliver the performance of valve actuators.
They establish a more advanced control system. -
Gate and valve stand
Stands can also be attached to meet the needs of customers.
