Translation guide
A control valve is a device used to regulate fluid flow, pressure, temperature, or level in industrial processes. In Japanese, the most common term is 制御弁 (せいぎょべん), but other terms exist depending on context.
A valve that modulates fluid flow in response to a control signal, used in process control.
The standard technical term for a control valve in industrial automation and process control.
この制御弁は流量を正確に調節します。
This control valve accurately regulates the flow rate.
Often used interchangeably with 制御弁, but can emphasize the regulating or adjusting function. Common in HVAC and general fluid systems.
調節弁の開度を変えて温度を制御します。
We control the temperature by changing the opening of the control valve.
Katakana loanword from English, widely understood in engineering contexts. Often used in product names or manuals.
このコントロールバルブは空気圧で作動します。
This control valve operates pneumatically.
Referring to a particular kind of control valve based on actuation or design.
An electrically actuated control valve. Common in building automation and remote control systems.
電動弁で温水の流れを制御しています。
We control the flow of hot water with an electric control valve.
A pneumatically actuated control valve. Often used in process industries where compressed air is available.
空気圧制御弁は応答が速いです。
Pneumatic control valves have fast response.
A hydraulically actuated control valve, used in heavy machinery or high-force applications.
油圧制御弁は高圧に耐えられます。
Hydraulic control valves can withstand high pressure.
When talking about a control valve within a particular context like automotive, plumbing, or appliances.
Flow control valve, emphasizing the regulation of flow rate. Used in hydraulic circuits and fluid systems.
流量制御弁でシリンダの速度を調整します。
Adjust the cylinder speed with the flow control valve.
Pressure control valve, used to maintain or limit pressure in a system.
圧力制御弁が故障すると危険です。
It's dangerous if the pressure control valve fails.
Idle control valve, specific to automotive engines for regulating idle speed.
アイドルコントロールバルブを清掃したら調子が良くなりました。
After cleaning the idle control valve, it runs better.
Both are used for control valves, but 制御弁 is more common in process automation and control engineering, while 調節弁 is often used in HVAC and building systems. In many contexts they are interchangeable.
コントロールバルブ is widely understood, especially in product catalogs and manuals. It's safe to use when you're unsure of the exact Japanese term.
