ZT-L12 Series Electric and Pneumatic Double Acting Spool Valve For Agricultural Machinery

ZT-L12 Series Electric And Pneumatic Double Acting Spool Valve For Agricultural Machinery

Bidirectional Flow Precision: The double acting spool valve structure of the zt l12 hydraulic valve ensures symmetrical flow control in both directions, with flow deviation within ±3%. This guarantees that farm tools like sprayer booms lift and lower at the same speed, avoiding uneven pesticide application.?

Dual-Control Responsiveness: Electric control achieves spool switching in 80ms for quick automated actions, while pneumatic control offers smooth manual adjustment-both modes work seamlessly with the double acting spool valve design to meet different operational needs.?

Agricultural Environment Adaptability: The valve body uses corrosion-resistant aluminum alloy, and seals are made of oil-resistant rubber, withstanding exposure to fertilizers and pesticides. It operates stably in temperatures from -10°C (cold spring planting) to +60°C (summer harvesting).?

Easy Installation & Maintenance: The zt l12 hydraulic valve adopts standard agricultural machinery interfaces, allowing direct replacement of old valves without modifying pipelines. Its modular spool design enables quick replacement of worn parts, reducing downtime during busy farming seasons.?

The zt l12 hydraulic valve excels in various agricultural machinery applications, demonstrating its versatility:?

• Tractor Implements: In tractor-mounted plows, the double acting spool valve controls the plow's lifting (to move between fields) and lowering (to till soil), ensuring stable depth adjustment for consistent plowing quality.?
• Seeder Systems: In precision seeders, the zt l12 hydraulic valve drives the opening and closing of seed metering gates. As a double acting spool valve, it ensures uniform seed release and reliable closure, avoiding seed waste or uneven spacing.?

In every application, this valve proves to be a reliable choice for agricultural machinery, combining the bidirectional control precision of the double acting spool valve with the agricultural adaptability of the zt l12 hydraulic valve.

ZT-L12 multi-way directional valve is a kind of medium-high pressure integrated multi-way directional valve independently designed and developed by our company. According to customer requirements, the valve is equipped with overflow valve, hydraulic lock, one-way valve, etc. Overflow valve can adjust the system pressure, one-way valve to prevent oil backflow, reversing valve slide valve function A, O, Y, P, etc., can be arbitrarily combined, reversing handle has two installation forms, to facilitate the operation of different directions, the valve USES parallel oil circuit, design pressure outlet and other hydraulic components to provide power source. Through the special design sealing way, causes the valve sealing performance to be remarkable. The valve is widely used in forklift, sanitation vehicles, small loader and other construction machinery hydraulic system.

 

Monoblock directional control valves has many outstanding features including high performance, high efficiency, small volume, mass flow, and leak proof.
