NIPPON gear#® ACTUATORPRODUCTS GUIDE

Advanced Technology Excellence in advanced technology and facilities Our valve actuators are structured in a quite compact and robust way, because of excellent design based on long experience as well as the use of highly-reliable materials. Adopting stable and reliable motors with large starting torque and extremely small inertia, our valve actuators do not always require a brake system due to wide range of self-lock function when operated at normal speed of opening and closing valves. As our valve actuators are designed to have a wide range of applications, they can be combined with the...

The opening and closing of valves Nippon Gear's valve actuators accurately control amounts of fluids in pipes, gates and tanks, and are especially useful in a harsh environment - typically mountains and wilderness, which tend to have heat waves, wind and snow, and extreme cold. Nippon Gear entered into a technical partnership with world-famous Philadelphia Gear (currently, Flowserve) in the United States in 1963, and started manufacturing UmitorqueP in Japan. Philadelphia Gear developed Limitorque in 1929, and has a long history as a pioneer. Recognized as a brand of durability and trust...

MULTI-TURN Multi-Turn Type Multi-turn type actuators drive sluice valves, globe valves, water gates, butterfly valves, etc. by linear movement. There are various models for attending to all needs, such as electric actuators as SMB and LI 20 series as well as manual actuators as BGA and PA series. SMB Automatic return model SMB series actuators are robust, and can be used under various environmental conditions since these are applied with pressure-resistant and explosion-proof, fire-resistant, water-resistant, radiation-resistant, etc. Geared limit switch and torque switch mechanisms enable...

JMB Manual return model with an electric interlocking switch Small-sized JMB-04 and 03 have a declutch lever, and medium-sized JMB-00 to large-sized JMB- 4 have a push-pull handle. For all models, manual/electric switching can be done with one-touch operation. The actuators are equipped with an interlocking switch which shuts off electric currents during manual operations. They can be used for various purposes, including sluice valves, globe valves and water gates. LI 20 series are compact and lightweight actuators based on SMB series. The adoption of aluminum die-cast achieved reduction of...

•Electric Actuator Super small JX-05M series are electric actuators developed for small globe valves and small gate valves. Making use of our wealth of long experience as a pioneer of valve actuators, we designed this series to meet customers’ demands. As a result of pursuing usability and safety, a hand wheel is included as a standard feature, and the automatic return mechanism is adopted for manual/electric switching. SMB Air series can be operated by using compressed air as the power source. SMB Air series are equipped with a rotary vane air motor, and the internal gear transmission...

Bevel Gear type BGA series are bevel gear actuators that can be attached directly to gate and globe valves that are subjected to thrust, realizing easy manual operations. By using an adaptor, the actuators can be easily attached to existing valves. In addition to the standard type, BGA series includes BGA-P type with a position indicator, BGA-S type with a limit switch, and BGA-W type with two orthogonal shafts. B series are bevel gear actuators for manual operations. By combining two B series actuators with an SMB series actuator, they can be used for opening/closing a double-spindle gate....

PART-TURN Part-Turn Type Part-turn actuators open/close butterfly valves, ball valves, plug valves, and dampers by rotary movement. Quarter turn type The NOM series electric actuators are actuators which are the most suitable for butterfly valves, ball valves, and small sized valves. Their offer torque ranging from 35 Nm/310 inlb to 4,500 Nm/40,000 inlb. A unique feature of this actuator is that the manual override can be operated without a clutch and a brake. We are able to attach other options such as chain type handles, and integral types. 3. Domed position indicator

•Manual Actuator HB Worm gear type HB series are actuators for the 90-degree rotation of butterfly valves, ball valves, and plug valves. At your request, we can manufacture actuators for different degrees of movement. HB series can be used for manual operations by attaching a handwheel, and also for electric operations by combining it with such Limitorque electric actuators such as SMB, JMB, and LI 20 series. HB series can be used by attaching a spur gear attachment (MSG) to the input shaft side. Umltorque® Size Max torque Electric rating (N-m) Manual Large-sized worm gear type H series are...

This type of actuators can be used in areas requiring explosion-proof measures. Two models are available: the Pressure-resistant-explosion-proof model, and the increased safety explosion-proof model. They are designed and manufactured in accordance with the standards of explosion-proof construction for electrical machinery and apparatus, and passed the inspection of the Technology Institution of Industrial Safety (TIIS) in Japan. #JIS Flameproof (pressure-resistant and explosion-proof) #JIS Increased safety explosion-proof •JIS Hydrogen explosion-proof #K0SHA explosion-proof (JIS= Japanese...

k Aaximum /V\ Torque Capacity List of Maximum Torque Capacity by Product In selecting a valve actuator, it is economical to choose optimum unit size and motor capacity. When you place an order or make an inquiry, please let us have the following data, so that we can select an economical unit size for you. ~ ■ Model number, bore, and structure of the valve ■ Fluid pressure and max. differential pressure ■ Valve system diameter (pitch lead) ■ Time for opening/closing ■ Stroke from the full-open position to full-dose position ■ Phase of voltage, voltage, cyde or DC electricity ■ Ambient...
