Duty Control Valve (DCV) representing HAMANAKODENSO

DVC

EVAP Purge Control Valve boasting the world’s top share

A DCV is an electromagnetic valve used for supplying gasoline vapors generated in the fuel tank to the engine based on the driving status, by controlling the flow rate in response to electrical signals. Our DCVs have been widely adopted by car manufacturers worldwide because of their excellent basic performance, including high accuracy, low noise, and high durability. Another reason for our DCVs’ success is our technical capabilities that enable speedy kaizen right after a failure has been identified, which is one aspect of “HAMADEN Quality.”

DCVs continue to evolve, helping to conserve the global environment.

DCVs work behind the scenes, in places unnoticed by car drivers. Precisely because they are out of sight, it is our mission to deliver safety with our products. Meanwhile, an evaporative control (EVAP) system actually contributes to preserving the global environment because it incorporates a DCV, capable of preventing gasoline vapors from being released into the atmosphere. By striving to realize zero emissions of gasoline vapors in cooperation with automobile manufacturers, we will help create a more ecological future through our products.

Six business domains and products

We introduce HAMANAKODENSO’s products adopted by automobile manufacturers worldwide, including DCVs (EVAP Purge Control Valves), boasting the world’s top share by business domain.

Horn business

Our first product, horn, which has a history of more than 70 years since our founding, is now regarded as one of the main products of HAMANAKODENSO.
A car horn is an acoustic device used as an alarm to notify a failure or danger to others. Our horn is not only incorporated in a car as a genuine part, but is also offered as an aftermarket part to be exchanged with a genuine part for its higher-quality sound. Two types are available: a trumpet-shaped type with a soft and sophisticated sound, and a flat type with a sharp and dynamic sound.

EVAP (evaporative emission control system) business

The EVAP (evaporative emission control system) business domain provides DCVs that boast the world’s top share and other products.
While EVAP regulations are strengthened worldwide to help preserve the global environment, we provide a wide array of products installed on vehicles to check for EVAP leakage or inhibit the generation of gasoline vapors. These products are required to deliver high performance in any environment.

Hydraulic control business

The Hydraulic control business domain provides hydraulic solenoids that control the vehicle’s performance to move, turn and stop, coils for hydraulic control units, and many other products.
We offer solenoids and coils that control transmission shifting or braking by controlling the hydraulic pressure of an automatic transmission (AT) or anti-lock brake system (ABS). To enhance a vehicle’s basic performance to move, turn and stop, we continually address product improvements jointly with our customers.

Valve system business

The Valve system business domain provides actuators including solenoids for intake/exhaust valve control.
We offer various actuators, such as solenoids installed on vehicles, to control the VCT system’s variable valves that control the opening and closing timing of the intake/exhaust valves in the engine combustion chamber according to the driving status. These products need to deliver excellent performance even under the extremely high-temperature environment inside the engine.

Sensor business

The Sensor business domain detects the present and controls the future of vehicles.
We offer many different sensors that perform controlling and correction functions in various situations, including checking engine coolant temperature or intake air temperature, and operational detection of the accelerator pedal or electronic throttles. As the vehicle’s electronic control system becomes increasingly sophisticated, our products are needed in a wider array of applications.
