Product Structure and Working Principle

（1） Structural Design

Material selection: The valve body is carefully crafted from all stainless steel material. Stainless steel material has excellent corrosion resistance and can operate stably for a long time in complex and harsh industrial environments such as high temperature, high humidity, and the presence of corrosive gases or liquids. It effectively resists the erosion of valves by environmental factors, greatly extending the service life of valves and reducing the probability of failures and maintenance costs caused by material problems.

Internal structure: The internal structure is compact and exquisitely designed, mainly including high-precision valve cores, valve seats, and sensitive and reliable driving devices. The valve core and valve seat are processed through advanced precision machining technology, with extremely high surface flatness and smoothness. The two are closely matched, which can achieve excellent sealing performance when the valve is closed, effectively preventing gas leakage and ensuring safety. The driving device is responsible for quickly and accurately driving the valve core action upon receiving the control signal, achieving rapid opening and closing of the valve and meeting different requirements during equipment operation. In addition, there is a special sealing structure inside the valve, which further enhances the sealing effect and ensures reliable operation under various working conditions.

（2） Working principle

Normal operation mode: During the normal operation phase of the equipment, the GSOV25HT cut-off valve is in the open state, and gas can smoothly pass through the valve and be stably delivered to the gas turbine and other equipment according to the preset flow rate and pressure of the system, meeting their normal operation needs for gas. At this time, the driving device remains powered on and maintains the valve core in the open position through electromagnetic force and other actions, ensuring smooth and unobstructed gas passage and ensuring the continuous and stable operation of the equipment.

Cut off working mechanism: Once the system detects an abnormal situation, such as equipment failure, emergency stop command, or a situation that may endanger safety, the control signal will be immediately transmitted to the driving device of GSOV25HT. After receiving the signal, the driving device quickly stops power supply. Under the action of spring force or other auxiliary power, the valve core moves to the closed position at an extremely fast speed, instantly completely blocking the gas passage and quickly cutting off all gas flow to prevent gas from continuing to flow to the equipment, effectively avoiding the occurrence or further deterioration of dangerous events. For example, when the gas turbine control system detects abnormal situations such as turbine overheating or overspeed that may cause serious accidents, it will immediately send a cut-off signal to the GSOV25HT cut-off valve. The valve will respond quickly and cut off the gas supply in a very short time to protect equipment and personnel safety.

Product specifications

Pressure parameters: This valve has strong pressure resistance, with a normal working pressure of up to 900 psi (6.2 MPa). Under such high pressure conditions, the valve can still perform stable opening and closing operations, ensuring reliable gas cut-off under different pressure conditions and meeting the strict requirements for high-pressure gas control in industrial production. At the same time, the valve is specially designed to withstand a certain degree of pressure fluctuations, ensuring normal operation in complex pressure environments.

Traffic performance: According to different application scenarios and system requirements, GSOV25HT exhibits good traffic adaptability. Its design can meet the cutting off requirements of gas flow for various types of gas turbines at different power outputs. For example, when a high-power gas turbine is operating at full load and requires a large flow of gas supply, this valve can quickly cut off the large flow of gas in emergency situations; Under low load conditions of low-power equipment, valves can accurately control the cut-off of small flow gas, efficiently completing tasks and ensuring the safe operation of equipment under various working conditions.

Fuel compatibility: It has a wide range of fuel compatibility and can be perfectly matched with various common gaseous fuels, including natural gas, propane, ethane, methane, etc. Moreover, it can also adapt to a certain proportion of hydrogen methane mixed fuel (such as a mixed gas with a volume ratio of up to 50% hydrogen) without the need for additional modifications. This feature provides the possibility to cope with future changes in energy structure and the application of new fuels, enhancing the universality of equipment in different fuel environments, and enabling relevant equipment to adapt to new fuel types without frequent valve replacement during the energy transition process.

Electrical specifications: The electrical interface design is flexible and diverse, suitable for various common voltage types, including DC voltages such as 24 Vdc and 125 Vdc, as well as AC voltages such as 115 Vac or 220 Vac. This design is easy to connect with different control systems and power sources, meeting diverse user needs and complex application scenarios. Whether in small industrial equipment using DC power or in large power generation facilities using AC power, the GSOV25HT can be easily adapted to achieve reliable control and operation.

Temperature applicable range: It can operate normally within a relatively wide temperature range, and the suitable gas temperature range is generally -4 ° F to+350 ° F (-20 ° C to+177 ° C). This means that whether in cold winter outdoor environments or in high-temperature industrial production sites, valves can operate stably, reliably achieve gas shut-off function, and are not significantly affected by temperature changes. For example, in the winter of cold northern regions, the gas temperature may drop very low, but the valve can still work normally; In some high-temperature industrial processing sites, even when the gas temperature is high, valves can maintain good performance to ensure the safe operation of equipment.

Closing time: The valve has an extremely fast cutting response speed. After receiving the cutting signal, it can complete the closing action of the valve in a very short time (usually less than 0.1 seconds), quickly cutting off the gas supply. This rapid response capability is crucial in emergency situations, as it can prevent dangerous events in a timely manner, provide strong guarantees for equipment and personnel safety, and effectively reduce the risk of accidents.

Sealing performance: Through optimized valve core and seat design, as well as the use of high-quality sealing materials, excellent sealing performance can be achieved when the valve is closed, meeting strict leakage standards. For example, under a certain pressure difference, almost zero leakage can be achieved, effectively preventing gas leakage when the valve is closed, further improving the safety and stability of the system, avoiding potential safety hazards caused by small leaks, and ensuring the safety of the industrial production environment.

Product Features

Quick cut-off function: With extremely fast cut-off response speed, it can complete the valve closing action in a very short time (usually less than 0.1 seconds) after receiving the cut-off signal, quickly cutting off the gas supply. This rapid response capability is crucial in emergency situations, as it can prevent dangerous events from occurring in a timely manner and provide strong guarantees for equipment and personnel safety. For example, when the gas leak monitoring instrument detects a combustible gas leak, the GSOV25HT shut-off valve can react instantly, quickly cutting off the gas, preventing the leak from further expanding, and avoiding serious accidents such as fires or explosions.

Fault safety function: Following strict fault safety design principles, in the event of electrical faults, loss of control signals, or other abnormal situations, the valve will automatically switch to the closed state, blocking the gas path and ensuring that the system is in a safe state. Even in complex fault environments, it can effectively reduce the risks caused by gas leaks or loss of control, providing multiple protections for the safety of the entire system. For example, when the control system fails and cannot send control signals normally, the valve will rely on its own fault safety mechanism to automatically close, preventing gas leakage from causing danger.

Sealing performance guarantee: Through optimized valve core and seat design, as well as the use of high-quality sealing materials, excellent sealing effect can be achieved when the valve is closed, meeting strict leakage standards. For example, under a certain pressure difference, almost zero leakage can be achieved, effectively preventing gas leakage when the valve is closed, further improving the safety and stability of the system, and avoiding potential safety hazards caused by small leaks. Whether in long-term use or under harsh conditions such as high pressure and high temperature, the sealing performance of the valve can be reliably guaranteed.

Remote control function: This valve can be connected to the control system to achieve remote control. Operators can remotely control valves from a centralized control room or remote location through the control system to achieve valve opening and closing. This function is particularly important in some large industrial facilities or hazardous environments, facilitating operators to respond to various situations in a timely manner and improving the convenience and safety of operations. For example, setting up GSOV25HT shut-off valves in the gas supply network of cities or factories can be centrally controlled in the control room, remotely controlled, and emergency shutdown of pipeline gas supply at the accident site, effectively responding to emergencies.
