How we can select?

7 Hydraulic valve (Directional)
판매전략 국산화가 진행되고 있는 관계로 NG6 valve에 대하여는 가격적인 경쟁력이 있음. 일본제품이 250bar인데 비해, 상대적으로 높은 압력인 350bar임. Din connector형으로, 일본제 단자 box type 교체에 어려움이 있음. DC solenoid valve의 경우 Din connector에 surge killer (varistor)가 장착되어 있음. 두산인프라코아, 두산메카텍 선반 기종 100%에 적용되는 valve임.
