Noah's hydraulic valves are renowned for their fast response, stable control, and long lifespan. This series of valves is specifically designed for complex hydraulic circuits, applicable to fields such as construction machinery, metallurgical equipment, automated production lines, machine tool equipment, and rubber and plastic machinery. They serve as core components for controlling the direction of hydraulic actuators (e.g., cylinders, motors).

Solenoid Directional Valve

Explore NOAH’s DSG solenoid directional valves—durable, low-noise, ISO-compatible valves rigorously tested for over 10 million cycles.

Features a powerful wet-type electromagnet and a 5-chamber valve body structure, capable of withstanding high pressure and back pressure.
The wet-type solenoid valve design results in low noise, long lifespan, high-pressure resistance, and fast switching.

Hydraulic Stack Valve

The hydraulic stack valve utilizes a modular design to integrate multiple functions such as directional control, pressure control, and flow control. This reduces piping connections and simplifies system design.

High compatibility: Adapts to ISO 4401 standard mounting surfaces, interchangeable with mainstream brand valve groups.
Reliable & durable: Valve spools undergo hardening treatment, ensuring a lifespan of over a million cycles.

Structure & Working Principle

Valve Body Design

Modular structure: Employs standardized interfaces, supporting multi-unit combinations for flexible adaptation to complex systems.
Material & craftsmanship: Valve body and spool are made from high-strength alloy steel, undergoing precision grinding and surface treatment for wear and corrosion resistance.

Control Method

Solenoid pilot control: An electromagnet drives a pilot valve, using hydraulic oil pressure to shift the main spool, thereby reducing energy consumption.
Manual emergency operation: Some models are equipped with a manual emergency button, allowing oil path switching even during power outages, ensuring system safety.

Core Advantages

High efficiency & energy saving: Low-power electromagnet design with a response time of ﹤30ms, enhancing system efficiency.
High compatibility: Adapts to ISO 4401 standard mounting surfaces, interchangeable with mainstream brand valve groups.
Reliable & durable: Valve spools undergo hardening treatment, ensuring a lifespan of over a million cycles.

How do I hook up a hydraulic valve?

To extend the cylinder, pull the handle away from the valve. When the handle is released, the valve spring will return to the neutral position, stopping the cylinder. Neutral: Oil circulates from the pump, through the valve, and back to the tank. Work ports are blocked. To retract the cylinder, push the handle towards the valve. When the handle is released, the valve spring will return to the neutral position.

Do hydraulic valves need adjusting?

Yes, hydraulic valves may require adjustment to optimize system performance, compensate for wear, or adapt to changing operating conditions.

How do you tell if a hydraulic valve is open or closed?

You can determine if a hydraulic valve is open or closed by checking the actuator position, monitoring changes in flow and pressure within the system, or by inspecting indicator markings on the valve body.
