Flow up to 60L/min

6/2 Hydraulic Solenoid Valves (12V, 60 l/min) – Precision Flow Control

6/2 hydraulic solenoid valves with a flow rate of up to 60 l/min and 12V DC coil power are advanced components designed for efficient division and redirection of the working fluid stream in hydraulic systems. These types of valves, commonly known as twin diverters or on-off proportional valves, allow for the control of two independent receivers (e.g., two double-acting cylinders) using a single control valve section. Flow direction switching is performed remotely under the influence of an electrical impulse, which eliminates the need to expand the system with additional, complete mechanical sections. This solution is widely used in agricultural, construction, and forestry machinery, where mounting space and system weight are strictly limited.

Application and technical characteristics

Six-way, two-position (6/2) valves with a nominal flow rate of 60 l/min are optimized for use with medium-power hydraulic systems. The body construction, usually made of high-strength nodular cast iron or hardened steel, guarantees resistance to high working pressures typically reaching 210-315 bar, depending on the manufacturer's specification. A precision-ground internal slider minimizes internal leakage, ensuring stable maintenance of the receiver's position under load.

These components exhibit full compatibility with mineral hydraulic oils (HL, HLP, HVLP) according to ISO 6743/4. The operating temperature range of the working medium is usually from -20°C to +80°C, which allows for trouble-free operation in extreme environmental conditions. The 12V DC electromagnetic coil is characterized by a high protection class (typically IP65 when using a dedicated ISO 4400 / EN 175301-803 plug), which protects the actuator against moisture ingress and dust.

Main areas of implementation for 6/2 12V 60 l/min solenoid valves:

• Front loaders (TUR): Control of a bale grab or a crocodile grab (so-called third section).
• Agricultural machinery: Plow turnover systems, control of sprayer arms, seed drills, and green forage machines.
• Construction and forestry machinery: Redirecting the oil flow to additional working equipment in mini-excavators or loaders.

To ensure maximum durability and reliability of the system, it is recommended to install filter elements. A properly selected hydraulic filter protects the valve slider from being blocked by solid contaminants.

Why choose our components? Technical benefits

Choosing the professional 6/2 solenoid valves available in our range brings measurable engineering benefits. Above all, the offered valves are manufactured with strict dimensional tolerances, which directly translates into the repeatability of system operating cycles. The threaded connections (mostly internal BSP 3/8" or BSP 1/2") are made in accordance with the ISO 228/1 standard, which facilitates integration with the rest of the installation. To connect the valve to flexible hoses, we recommend using threaded fasteners, such as standardized hydraulic fittings guaranteeing connection tightness under high pressure. Additionally, the design of the valves allows them to be combined into blocks (in series), which allows for the handling of three or more receivers while maintaining a single power supply. 12V coils are characterized by optimal current characteristics, without excessively loading the vehicle's electrical installation.

Frequently Asked Questions (FAQ)

1. Can a 6/2 12V 60 l/min solenoid valve operate continuously under voltage?
Yes, modern electromagnetic coils are adapted for continuous operation (ED 100%), which means they can remain under voltage for an unlimited time without the risk of burning out the winding, provided that proper heat dissipation and operation within the permissible ambient temperature are ensured. However, it should be remembered that long-term power supply to the coil causes its natural heating (even up to temperatures of 80°C), which is a physically normal phenomenon for this type of electromagnet.

2. What are the consequences of exceeding the nominal flow of 60 l/min?
Exceeding the nominal flow rate causes a rapid increase in hydraulic resistance, which generates high pressure losses (so-called pressure drop $\Delta p$). The consequence of this is intense heat generation in the internal structure of the valve and accelerated thermal degradation of the oil. In extreme cases, the hydrodynamic forces acting on the slider may exceed the strength of the electromagnetic field generated by the 12V coil, which will prevent full and correct shifting of the valve.

3. What is the drain connection in 6/2 solenoid valves for and do you always need to connect it?
The drain connection (often designated as port L or Y) discharges internal leaks from the slider chambers directly to the oil tank. In models equipped with an external drain, its connection is strictly technically required if the pressure at the return ports exceeds the permissible return value for the slider seals (usually above 25-50 bar). Failure to connect the drain line under such conditions leads to blocking the slider in an intermediate position or permanent damage (bursting) of the valve's dynamic seals.

4. How to correctly connect the solenoid valve to the installation using hydraulic control valves?
The 6/2 solenoid valve is mounted in series behind the existing control valve section. The two input ports of the solenoid valve (usually labeled as P1 and P2 or A and B) are connected to the working outputs of the selected section, which is controlled by a hydraulic control valve monoblock or sectional. The four output ports of the 6/2 valve (A1, B1 and A2, B2) are led out directly to two separate receivers. Applying 12V voltage to the coil determines which pair of outputs (index 1 or index 2) the pump output caused by the mechanical deflection of the main control valve lever will be redirected to.
