The direct acting relief valve is used for limiting the system pressure by adjusting handle directly. This valve is used for the higher pressure machine with small flow rate, such like an elevator as a device for safety protection.
The Key part of direct acting relief valve DBD type is the spring, we are using high quality of import spring raw materials, there is a little spring deformation after long term and under higher pressure. Finotek DBD direct acting relief valve is installing all kinds of hydraulic units or system as pressure regulation or safety valve, the important items for sealing the pressure are made by high strength steel and all hardened after finishing. The DBD is threaded connection, but it can be changeable to subplate mounting by blocks.The max. adjustment pressure can reach to 40Mpa of DBD series.
