Product Introduction

SQZD-L15 Series Pneumatic Hydraulic Directional Control 3 Spool Valve Monoblock

The multi-loop control core of the pneumatic and hydraulic system

In pneumatic-hydraulic hybrid systems-such as those in automated assembly lines, packaging machinery, and light industrial equipment-simultaneous control of multiple hydraulic circuits is key to improving operational efficiency. The SQZD-L15 Series Pneumatic Hydraulic Directional Control 3 Spool Valve Monoblock is designed to meet this demand, serving as a centralized control component that coordinates multiple hydraulic actions. As a practical 3 spool valve, it integrates three independent spools into a single monoblock structure, enabling separate control of three hydraulic circuits without mutual interference. The sqzd l15 hydraulic valve is particularly suitable for scenarios requiring synchronized or sequential operations, such as multi-station packaging machines or assembly line lifting devices.

Core advantage: Balancing multi-loop control and operational stability

The sqzd l15 hydraulic valve stands out in hybrid systems with its ability to control multiple circuits while maintaining stable operation. Its three spools are independently adjustable, allowing precise flow and direction control for each circuit-whether it's controlling a clamping cylinder, a lifting cylinder, or a pushing cylinder. This 3 spool valve adopts a pneumatic control mode, which responds quickly to control signals (spool switching time <80ms) and is easy to integrate with automated control systems, reducing manual operation intensity.

Another key advantage of this sqzd l15 hydraulic valve is its compact and reliable structure. The monoblock design, as a 3 spool valve, reduces the number of connecting pipelines by more than 50% compared to separate single-spool valves, saving installation space and minimizing potential leak points. The valve body is made of high-strength aluminum alloy with anti-oxidation treatment, and key seals use wear-resistant materials, ensuring stable operation in environments with frequent start-stop cycles.

Technical features: Tailor-made for multi-action coordinated control

Independent Spool Control: Each spool of the 3 spool valve can be adjusted separately in terms of flow and direction, supporting both synchronized actions (such as simultaneous lifting of two workbenches) and sequential actions (such as clamping first and then conveying).
Pneumatic-Hydraulic Integration: The sqzd l15 hydraulic valve uses pneumatic signals to control hydraulic spools, combining the fast response of pneumatics with the stable power of hydraulics, making it suitable for automated production scenarios.
Easy System Expansion: With standard interface sizes, it can be connected to additional auxiliary valves, adapting to the expansion of equipment functions without major modifications to the original system.
Strong Environmental Adaptability: The valve body has good dust and moisture resistance, and can operate stably in temperatures ranging from -10°C to +70°C, adapting to the working conditions of general workshops.

Product Description

SQZT-L20 series pneumatic control valves are developed on ZT-L20 manual control valves. It changed the control way of these valves, especially, it can be controlled by remote control with the pneumatic control way. The power beyond function is on the SQZT-L20 series, it is able to be connected with other hydraulic valves in series. The features of this monoblock construction SQZT-L20 pneumatic control valves are compact construction, high working pressure, better working performance, reliable working, remote controlling and etc. Besides that, the manual control can be used with the pneumatic control together. The valves are widely used on mechanical machines, sanitation machines, mining machines and other machines' hydraulic systems.
