RD5200 Directional Control Valve
Core advantages of RD5200 integral multi-way reversing valve Advantages of high strength and durability of valve body structure
The integral cast steel integrated valve body is made of high-strength gray cast iron, with peak pressure of 21MPa (3000PSI) and rated flow of 100L/min. It is resistant to impact and site vibration, and is not easy to deform and leak oil.
The valve core is hard chrome-plated, wear-resistant and corrosion-resistant, with little wear under heavy load for a long time. There are few sealing points between the pieces, and the oil leakage failure rate is far lower than that of the piece-type multi-way valve.
Each load check valve is built in to prevent the backflow of oil in the cylinder, the equipment will not automatically settle when it is still, and the locking of wood grabbing and lifting conditions is stable. Safety and stability advantages of pressure and oil circuit It is equipped with differential cone overflow valve, with adjustable pressure of 1500 ~ 3000 PSI and optional low pressure of 500 ~ 1500 PSI. It can automatically relieve pressure when overloaded to protect the oil cylinder, oil pipe and hydraulic pump from overpressure damage.
It supports the modification of open center/closed center, and can be equipped with power bypass oil circuit and Multi-Action parallel oil supply.The compound action will not grab oil, the synchronization of lifting and stretching is good, and the problem of weak action is very few.
In the middle unloading design, the equipment is ready for the no-load operation of the pump body, the oil temperature rises slowly, and the fuel consumption is lower.
Control feel and expansion of adaptation advantages Manual lever direct drive structure, accurate spring reset, clear gear, fine micro-control, no material grabbing, fine adjustment and lifting; support the selection of the fourth gear of the floating position, the handle can be installed reversely, the solenoid valve and pneumatic control module can be installed in the later stage to transform the electric control/pneumatic control operation, without replacing the main body of the valve body; BSP British system, metric system, NPT thread interface options, slide valve machine
