■ FEATURES
Various applications for construction equipment, various types of plant equipments and freezing machine field.
1. Because this valve is a pilot direct operated type, it does not need auxiliary equipment such as an electric and a compressed air. Its capacity is larger than direct operating valve.
2. Pressure adjusting range is wide and pressure adjusting range is easy. (JRV-SF11: 0.35~8kgf/㎠{0.035 ~ 0.8MPa}. JRV-SF21: 0.35~16kgf/㎠{0.035~1.6MPa})
3. This valve has a built-in filter and the filter prevents mal-functions of valve due to the scale and impurities and shows an excellent performance
