    China JYFJS-011 Aluminum Alloy Electromagnetic Shut-off Valve - Gas Safety Solutions from Reliable Suppliers and Factory

    Product Overview

     

    The JYFJS-011 is a state-of-the-art gas emergency shut-off valve manufactured by our company in China. Designed to ensure the highest level of gas safety, this valve is essential for the emergency shut-off of gas pipelines. It seamlessly integrates with gas alarm systems, fire protection measures, and other intelligent terminal control modules, allowing for both automatic and manual emergency shut-off of gas sources. Compliance with gas incident handling requirements is guaranteed, as the valve must be manually opened to meet stringent safety handling standards.

     

    Application

     

    Our JYFJS-011 gas emergency shut-off valve is extensively used across various industries, including petroleum, chemical, environmental protection, metallurgy, refining, gas distribution, biochemical medicine, and agriculture. As a leading supplier, our factory prioritizes quality and safety, making the JYFJS-011 an ideal choice for businesses looking to enhance their gas safety protocols.

      🔒

      This valve is a normally open shut-off valve with a holding control mode. It remains open without power during normal operation and can automatically close upon receiving a shut-off signal. After closing, it can be manually opened and will automatically close again upon receiving another shut-off signal.

      ⚡

      When a leakage accident occurs, the alarm system sounds an alert, instantly providing a DC pulse voltage to the solenoid valve. The coil is energized, driving the valve to quickly close, cutting off the gas source and entering a self-locking state.

      🔔

      When a gas leak occurs, the alarm's capacitor continuously releases a 3-second DC pulse voltage, energizing the coil, closing the valve to cut off the gas supply, and entering a self-locking state.

      ⚙️

      The interaction of instantaneous electromagnetic force of the coil, permanent magnetic force, and spring force is used to achieve pulse drive, automatic valve closing, and manual valve opening self-holding functions.

      Frequently Asked Questions (FAQ)
      Q What is the default state of the JYFJS-011 solenoid valve — open or closed?
      The JYFJS-011 is a normally open valve. It remains in the open position during normal operation without any power supply. It only closes when it receives a shut-off signal (DC pulse voltage), making it safe and energy-efficient for continuous use.
      Q How does the valve respond when a gas leak is detected?
      When the alarm system detects a gas leak, it instantly delivers a DC pulse voltage to the solenoid coil. The energized coil drives the valve to close quickly, cutting off the gas supply. The valve then enters a self-locking state to prevent accidental reopening.
      Q How long does the capacitor release the DC pulse voltage during a gas leak event?
      During a gas leak event, the alarm's capacitor continuously releases a 3-second DC pulse voltage. This is sufficient to fully energize the coil, close the valve, and engage the self-locking mechanism to maintain the closed state.
      Q Can the valve be reopened after it has been automatically closed?
      Yes. After the valve has been automatically closed and entered the self-locking state, it can be manually reopened by the operator. Once reopened, the valve will automatically close again upon receiving the next shut-off signal from the alarm system.
      Q What forces are involved in the valve's operation mechanism?
      The valve operates through the interaction of three forces: the instantaneous electromagnetic force from the solenoid coil, the permanent magnetic force, and the spring force. Together, these forces enable pulse-driven closing, automatic self-locking, and manual opening with self-holding capability.
      Q What are the key internal components of the JYFJS-011 valve?
      The JYFJS-011 consists of 9 main components: Valve body, Diaphragm, Valve cover, Spring, Actuator, Reset Device, Dust cover, Moving iron core, and Sealing ring. Each component plays a critical role in ensuring reliable, safe, and efficient gas shut-off operation.
