SD8 Directional Control Valves

SD8 Directional Control Valves

Core advantages of SD8 wood grab valve (Directional control Valve): 

High pressure and large flow, multi-way controllability, strong modularization, flexible control, safety and durability, and adaptation to the working conditions of the wood grab. 

 1. High pressure and heavy load, powerful snatch  -315 bar high pressure, large flow of 90L/min, suitable for 10 – 25 ton wood grab, sufficient power for grabbing/rotating/lifting. -Each link with load holding valve + main overflow valve to prevent arm drop and overload, and the chain will not drop under heavy load. -a sheet structure,1 – 12 units are optional, which can meet the synchronous control of Multi-Action such as wood grab, boom, arm, rotation, etc. 

 2. Precise and controllable, smooth movement  -Precision grinding of valve core, good micro-motion, no stuttering at low speed, no shaking at high speed, log grabbing and alignment. -Support manual/electromagnetic/electro-hydraulic/flexible shaft/remote control, can be equipped with handle/pedal, comfortable cab control. -Parallel/series/composite circuit options, Multi-Action coordination without interference, efficiency increased by 30% +.

3. strong modularity and flexible adaptation  -Piece type superposition design, increase or decrease the number of units as required, refitting/maintenance without replacing the whole valve. -The installation spacing is 41 mm, and the compact size fits the narrow installation space of the wood grab. -Universal ports G1/2, G3/4, SAE10, compatible with mainstream pumps/motors/lines, low replacement cost. 

 4. Solid and durable, reliable in harsh working conditions  -High strength cast iron valve body, shock and vibration resistant, dust/muddy water/low temperature resistant (-40 ℃ ~ + 80 ℃). -Seals resistant to high pressure.
