The DSV type progressive distributor is an integral block structure with high oil pressure, strong shock resistance, overall dust and corrosion resistance, suitable for various harsh environmental conditions. The number of oil outlets of DSV type distributors is generally 6 to 20, and the displacement of each outlet is 0.20ml/cyc. The number and displacement of oil outlets of the distributor can be changed by merging the outlets. Each oil outlet joint is equipped with a one-way valve, which can effectively prevent oil return.
