山野產品依據IEC標準規範如下:

啟動頻率=Ï100%


休息時間 ()



●假設產品規格為OM-2,運轉時間為15秒,啟動頻率30%
→ 【15 x (1-30%)】/ 30% = 35,休息時間需35秒。

●假設產品規格為OM-2,運轉時間為15秒,啟動頻率75%
→ 【15 x (1-75%)】/ 75% = 5,休息時間需5秒。

※ 建議:當啟動頻率較高時,請選擇啟動頻率75%之產品,避免過載。
※ 一個循環 = (0 ° ~ 90 °) 運轉時間+休息時間+(90 ° ~ 0 °) 運轉時間+休息時間
安裝驅動器前,請先確認閥的扭力值是否小於驅動器的輸出扭力值 (所需之扭力大小,建議為閥最大扭力值乘上 1.3 之安全係數 )。

● 假如 5”閥門最大扭力為 80 N‧m  80 × 1.3 (safety factor) = 104 N‧m
104 N‧m < 150 N‧m (OM-3) → 可以安裝!
104 N‧m > 90 N‧m (OM -2) → 不可安裝!

在安裝驅動器前請確認閥類出力軸尺寸與法蘭孔距是否規格相符,如不相符,可使用連軸器或固定座以利組裝。
An Electric Valve Actuator means that the actuator uses electricity as an energy source in a control system. The electric control valve actuator receives an electric signal such as an adjustment meter, and changes the manipulation amount according to the magnitude of the signal. So that the amount or energy of the input or output control object is changed, and the automatic adjustment purpose is achieved. 
In industrial production, electric control valves are the most widely used. The electric regulating valve is composed of two parts: an actuator and an adjusting mechanism (valve).
Each electric valve actuator enclosure has a rating or meets specific standards. The NEMA(National Electrical Manufacturer’s Association) prepares standards which define the actuator with operating and service conditions, reference to construction and material composition and performance and quality etc. 
For non-hazardous locations, it is best to use a 4X rating. For hazardous locations, grades 7 and 9 rating are required. The IEC(International Electrotechnical Commission) seal code is similar to the NEMA standard. The IP rating specifies the level of protection against dust and liquid ingress. IP67 is often a level that is easily achieved in most commercial and industrial applications.
Electric Valve Actuator applied to industrial technology, irrigation, water treatment, HVAC, chemicals, food processing, mining, tunnel/metro ventilation, smoke extraction, food industry, environmental protection system, and so on.
The hot types of electric valve actuator series :
  • Quarter-Turn Electric Valve Actuator : OM series
  • Spring Return Electric Valve Actuator : S series
  • Electric Linear Actuator : L series
  • Explosion Proof Electric Actuator : OME series
