Description:

The Rexroth Direction Valve SL20PA1-43 is a hydraulically operated check valve, of the seated valve type, with pilot-operated operation. It is hydraulically actuated and can reliably block the flow of oil at selected ports. The valve has an external pilot return function and a connection diagram according to ISO 5781-08-10-0-16. It has a maximum operating pressure of 315 bar and a flow rate of up to 350 L/min. The Rexroth Direction Valve SL20PA1-43 is a hydraulically operated check valve that reverses the flow of the check valve by controlling the flow of hydraulic oil. When the control oil circuit is not connected to the pressure oil, the working principle of the valve is the same as that of an ordinary check valve, and the oil can only flow from the inlet port to the outlet port, and cannot flow in the reverse direction. When the control oil circuit has control pressure input, the piston mandrel moves to the right under the action of pressure oil, and the check valve opens, so that the inlet and outlet ports are connected, and the oil can flow in the reverse direction. The valve is a seat valve structure, the use of elastic sealing ring seat, has a good sealing performance, no noise, can effectively check back. It also has pre-opening function and external pilot oil return design, which can enhance the control performance. It has a maximum working pressure of 207 bar (3000 psi) and is suitable for use in a wide range of hydraulic systems.

Areas of application:

The valve is used in a wide range of industrial scenarios where precise control of the direction of flow of hydraulic fluid is required, including but not limited to:
Hydraulic systems: for controlling the unidirectional flow of hydraulic fluid and preventing backflow.
Machine building: in a variety of mechanical devices, for hydraulic support and control.
Mining Machinery: plays an important role in hydraulic support equipment for coal mining machinery.
Industrial automation: for automated production lines that require high reliability and precise control.
Coal mining machinery: In the hydraulic support equipment of coal mines, the valve can ensure one-way flow of hydraulic oil, prevent backflow of oil and ensure stable operation of the equipment.
Engineering machinery: such as excavators, loaders, etc., can control the flow and pressure of oil in the hydraulic system to achieve precise control of various actions.
Metallurgical machinery: It is used to control the flow of hydraulic fluid in metallurgical equipment to ensure the normal operation and safe production of the equipment.
Other fields: It can also be applied in the hydraulic system of ships, aerospace, automobile manufacturing and other fields.

Advantages:
High reliability: The valve has undergone rigorous sealing tests at maximum working pressure to ensure no leakage.
Flexible control: Pilot operated and can be reversed opened by external control of the hydraulic pressure.
Adaptable: Supports a wide range of hydraulic fluid types, including HL, HLP, HLPD, HVLP and HVLPD.
Compact design: Compact design and weight of only 4.8 kg make it ideal for space-constrained applications.
Durable: NBR seals enable operation in ambient temperatures from -30°C to +80°C.
Good sealing: Adoption of elastic sealing ring seat or floating sealing ring and other designs, with excellent sealing performance, effectively preventing oil leakage.
Strong control performance: with pre-opening function and external pilot oil return design, can achieve precise control of the oil flow.
Wide range of application: can be applied to a variety of hydraulic systems and working environment, with good compatibility and adaptability.
