Q45DT-4OT Hydraulic Control Valve

Core advantages of Q45DT-4OT quadruple integral multi-way valve  Hardware advantages of structure and working condition 

 1. One-piece cast steel valve body is strong and durable Integrally cast valve body, 4-way 4OT standard mid-position oil return structure, few sealing points between pieces, greatly reducing the probability of oil leakage; 315 bar peak pressure, rated flow of 45 ~ 60 L/min, suitable for heavy intermittent operation of small and medium-sized engineering machinery, strong impact and vibration resistance. 

2.4 The design of OT middle oil circuit is highly practical. The middle unloading oil return is smooth,The no-load standby of the pump body has low power consumption and slow oil temperature rise, and is more fuel-efficient after a long time of standby; the pressure maintaining at the middle position is stable, the oil cylinder is not easy to settle when the oil cylinder is static, and the static locking effect of a wood grabbing machine, a forklift and a small loader is good. 

3. Modular quadruple fixed layout The factory quadruple integration is regular, the external oil pipe arrangement is simple, the equipment installation space is small, and the pipeline layout cost is lower. 

 Handling performance advantages 

 1. Manual DT reversing feels smooth The valve core spring is stable in reset, the gear is clear, and the micro-motion control is exquisite.The low-speed action is not stuck and does not move, and the fine grasping and lifting operation has good hand feeling; the handle can be adjusted in multiple angles, and the fatigue of long-time operation is low. 

2. Multiple actions do not interfere with each other. Four-way independent oil circuit control, multi-cylinder synchronous action and uniform diversion, will not appear the problem of single action to grab oil leading to the weakness of other mechanisms, and the stability of compound operation is high.

 3. With overflow voltage stabilization protection Built-in main relief valve is adjustable (175bar reference adjustable), overload automatic pressure relief, to prevent the cylinder, oil pipe and power unit from overpressure damage, with overload protection to lift the whole machine.
