The SAV type 2-position 2-way directional valve uses a DC motor to drive the valve core to move. It is an integrated reversing control device that opens and closes the oil supply pipeline or switches the oil supply direction. Even under harsh working conditions ( Such as low temperature or high viscosity grease), the action is still quite reliable. This valve is suitable for use in dry and thin oil centralized lubrication systems with nominal pressures below 40MPa and in main branch pipelines of hydraulic systems. It can also be used in three types: 2-position 4-way, 2-position 3-way and 2-position 2-way.

Specification

Model SAV
Operating pressure 40 MPa
Reversing time 0.5 seconds
Motor power 40 W
Voltage 220VAC, 24VDC
Motor torque 20 N.M
Lubricant Grease NLGI 0~3# or Oil ＞ N68
Operating temperature (-20℃ ~ +80℃)

Instruction

1. The valve should be installed at the front end of the controlled main and branch pipelines of the system, and should be located in a ventilated, dry, easy-to-inspect location where there is no interference from moving mechanisms around it.
2. When used as a 2-position 2-way, the oil outlet “B” and oil return port “R” must be blocked.
3. When used as a two-position three-way, the oil outlet “B” must be blocked.
4. Connect the electronic control wiring according to the principle shown in the figure above.

]]> 20MPa DR4-5 Hydraulic Reversing Valve For Dual Line System https://www.jinpinlub.com/product/20mpa-dr4-5-hydraulic-reversing-valve-for-dual-line-system/ Fri, 13 Sep 2024 08:53:41 +0000 https://www.jinpinlub.com/?post_type=product&p=3668 Feature

It is used for electric centralized lubrication system, which alternately sends the lubricant output from the lubrication pump to two oil supply main pipelines. The valve has its own pressure regulating function and can automatically change direction. The reversing set pressure can be adjusted from 0 to 20MPa. The structure is simple and the reversing is reliable.

Specification

Model DR4-5
Operating pressure 3.5~20 MPa
Factory set pressure 10.5MPa
Applicable system Ring and spray type dual line system
Compatible pump Dual line pumps such as BSB and GP pumps
Net weight 7kg

Application

Engineering machinery uses the DR4-5 hydraulic reversing valve to control the hydraulic cylinder and hydraulic motor moving direction.
Industrial equipment: In hydraulic press, injection molding machine, numerical control machine tool and so on, the function of automatic control equipment is realized through hydraulic valve DR4-5.
Agricultural machinery: Such as tractor and combine harvester, hydraulic system control uses reversing valve DR4-5.
Lubrication system: especially in electric terminal centralized lubricating system, DR4-5 hydraulic reversing valves distribute lubricants alternately to different lubrication oil supply pipes.
