THM-TSL/V-2/3/5/V-CAN/VB0124/PA222-Proportional Spool Valves

Description

THM – TSL – Proportional Directional Spool Valves

TSL – Proportional Directional Spool Valves Types: 

TSL/V-2/V-3/V-5

• Pmax = 400/420bar
• Qmax = 60lpm/120 lpm/240 lpm

Load-sensing Proportional directional spool valves types series 3 can be used in constant displacement pump and variable displacement pump hydraulic system. Stepless speed regulation can be carried out on the cylinder or motor by means of electronic control manual and hydraulic control.

The output flow is only proportional to the input current signal or handle lever, and the speed is independent of the load, so several actuators can work at different pressure and speed independently until the total required flow rate of the actuator is greater than the maximum flow rate that the pump can provide.

The valve contains three functional blocks: connection block, directional valves and end plate.
Each function block has different functions for option.
Maximum of 12 sections in each bank of valve.

TSL/V-CAN

• Max Pressure420 bar
• Max Flow 240 L/min
• Typical Application: Pump trucks, Cranes, Boom Lifts, etc.

CAN bus-control proportional directional spool valve is based on the load-sensing principle. It is proportional directional spool valves. Each directional valve is integrated with proportional solenoid, spool position sensor and digital closed-loop controller, which ensures that the main spool valve moves fast with high-precision position control ability.

By presetting optimized dither signal and high-performance control algorithm, and the output flow of the proportional directional spool valves is more accuracy, this help the operator getting excellent control accuracy when they controlling the equipment. Therefore, this valve is the best choice for closed-loop or high-precision control application.

Technical features

1. Small dead zone, fast response, easy to achieve closed-loop control of cylinder position.
2. Closed-loop control of multi-way valve spool position, with smaller hysteresis and higher repeatability of output flow.
3. Simplified wiring, only 4 wires are needed for the whole set of Proportional directional spool valves, power line”, CAN-H and CAN-L bus signal lines.
4. Each directional valve is equipped with a parallel double DEUTSCH connection socket, which can be connected to the host computer separately.
5. Quick connection between valves via double plugs for easy maintenance and repair.
6. Plug terminal resistor (120) can be installed in the first or last connection of the Proportional directional spool valve as required.
7. With fault diagnosis function, easy to troubleshoot.

TS-VB0124

• Maximum pressure:150bar
• Maximum flow rate:30L/min
• Typical application: Agricultural machinery

VB00124 is a five block Proportional directional spool valves. It is a unified modular design, which can provide a reliable system solution for agricultural machines. The user can combine the valve body according to the functional requirements, which is simple and reliable.

These five block Proportional directional spool valves consist of an oil inlet link, five working links and a tail link. The inlet link is a solenoid relief valve, which is used for over-limit protection of the working mechanism. When the solenoid valve is in the middle position, the hydraulic lock can prevent the mechanism from sinking.
