FGSDFBDF series numerical-controlled electro-hydraulic valve is a valve, which is controlled by electromagnetic pilot vlave and hydraulic-operated by driving the diaphragm of main valve by means of thepressure of the medium itself. It is a newly neveloped advanced numerical-controlled electro-hydraulic valve ( herein after referred to as electro-hydraulic valve-DYF). It is the newest products.
This series of valves can be widely used for receiving/distributing systems of oil tankages, automatic control system of oils, quick oil supplying system, automatic filling system, automatic fire-fighting control system, city water supplying system, closed-type heat supplying system and agricultur alirring ation system etc in industries such as petroleum, chemical, fire-fighting and water-supply etc.
This valve can be automatically controlled and also be manually controlled. According to user’s requirement, power voltage AC 220V or DC 24 V can be used.
FBDF series numerical-controlled electro-hydraulic valves have passed the national explosion-proof examination, and have acquired explosion-proof certificate of conformity. Explosion-proof certificate NO.CE031340, Anti-hazard Classification: Exd ⅡBT4.
This valve can be computer-controlled with special software to automatically control the flow-rate, speed and pressure of medium to be conveyed. It has the functions such as stabilizing the flow-rate and stabilizing the pressure etc.
