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

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.

Product Description

Working Principle and Structural Diagram
Working Principle Diagram
🔒

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)
QWhat is the default state of the JYFJS-011 solenoid valve?
The JYFJS-011 is a normally open valve. It remains in the open position during normal operation without any power supply.
QHow does the valve respond to a gas leak?
Upon detection, the alarm sends a DC pulse to the coil, driving the valve to close and enter a self-locking state to cut off the supply.
QHow long is the pulse duration for the shut-off signal?
The capacitor releases a 3-second DC pulse voltage, which is sufficient to energize the coil and engage the locking mechanism.
QIs manual intervention required to reopen the valve?
Yes, after an automatic shut-off and self-locking, the valve must be manually reopened to resume operation.
QWhat forces drive the valve mechanism?
The operation relies on the interaction between instantaneous electromagnetic force, permanent magnetic force, and mechanical spring force.
QWhat are the main parts of the valve?
The valve consists of 9 core parts including the valve body, diaphragm, actuator, and internal sealing components for reliable performance.
