Guangzhou Dusterloh Machinery Co., Ltd

1. subplates for valve assembly with standardized port patterns without pressure limitation.

Subplates for valve assembly DN6/DN10 according to DIN24340 (ISO 4401 - CETOP - RP121H) and DN8 according to ISO 10372-4.Combinations with integrated brake control are available.
2. subplates for valve assembly with standardized port patterns with pressure relief MHDB16.

Valve assembly with pressure relief and feed > 1.5 bar by 2 pressure feed valves MHDB16K2-2x420VFB (pmax. = 420 bar, Qmax. = 100 l/min). The integrated feed check valves open from 1.5 bar. In order to prevent a feed-out, the feed pressure at port "E" must be higher, or an additional protection by an external check valve at port "E" is recommended. Combinations with variant 1 available.
3. subplates for valve assembly with standardized port patterns with DBDS10 pressure relief.

Valve assembly with pressure relief and supply >0.1 bar by 2 direct operated pressure valves DBDS10K1x/315bar (pmax. = 315 bar, Qmax. = 80l/min). The separate feed check valves open at >0.1 bar. Combinations with variant 1 are also available.
4. sub-bases for valve assembly with standardized port patterns with DDP16 pressure relief.

Valve assembly with pressure relief and supply > 0.1 bar through a pilot operated double pressure valve DDP16ENxxx (pmax. = 480 bar, Qmax. = 400 l/min) or DDP32ENxxx (pmax. = 480 bar, Qmax. = 700 l/min). The valve pressure setting applies to both directions of rotation. The valve with leakage line "L3" always works against the leakage pressure. Combinations with variant 1 are available, on request also with valve bodies > DN10.

Hydraulic motors KM 11 - RM 11

In radial piston engines, seven radially arranged pistons act on the crankshaft via a heptagonal ring with needle cage. In the KM 11 engine type, control is by means of translational movement of the control ring and gap seal to the housing. The RM 11 radial piston engine, on the other hand, has a backlash-adjusting control system. This makes the motor less sensitive to the effects of pressure and temperature and reduces leakage.
