DBD Direct Type Relief Valves

DBD series relief valve is a direct type seat valve for limiting the pressure in hydraulic systems. It has characteristics of small volume, compact structure, high performance, reliable work, low noise and long service life. The structure of this valve can be divided into poppet type valve(Max. 40Mpa) and ball valve(Max.63Mpa). There are 7 kinds of pressure class: 2.5£»5£»10£»20£»31.5£»40£»63Mpa. These series are wildly used in small hydraulic system as safe valves or remote control valves.
