The 3011-D5 normally open two-way solenoid valve, designed specifically for safety priority scenarios, has now been launched. This product defaults to maintaining the circuit when not powered on, and only closes the flow path when powered on, providing a reliable safety guarantee for your system. Adopting a universal 6X4 intubation interface, it is easy to install and responds quickly, making it an ideal choice for achieving safety interlocking and power-off protection in automation control systems.
Core advantages of the product:
Normally open design, safe and reliable: The core adopts the normally open (NO) working principle. In the event of an unexpected power outage or system failure, the valve will automatically restore its path state, effectively preventing system lockout and ensuring equipment and process safety, especially suitable for applications that require fault protection.
Wide medium compatibility: Suitable for various neutral media such as compressed air, water, inert gases, and hydraulic oil. The valve body material ensures its long-term stable operation in general industrial environments.
Quick response and long lifespan: The optimized electromagnetic coil and internal structure ensure that the circuit can be quickly and reliably cut off when powered on, with precise action and durability.
Convenient intubation connection: The standard 6mm intubation interface (6X4) eliminates the need for complex tools and thread sealing operations, greatly simplifying installation steps and saving time and cost in tube laying.
Compact structure saves space: The exquisite valve body design is easy to integrate into devices with limited space, providing convenience for the overall layout of the machine.
Typical application scenarios:
This product is widely used in safety blowing systems, burner control, irrigation systems, medical equipment, alarm systems, and any critical occasions that require "power-off ventilation/liquid supply" to ensure safety. It is an essential control component for improving equipment safety levels.
If your system needs to maintain smooth flow during power outages, the 3011-D5 normally open solenoid valve will be your best choice. Welcome to contact us for detailed technical specifications and quotations. We provide you with professional technical support.
