Product Structure and Working Principle

（1） Structural Design

Material selection: The valve body is made of all stainless steel material, which has excellent corrosion resistance and can adapt to various complex and harsh industrial environments. Whether it is high temperature, high humidity, or places with corrosive gases, it can ensure the long-term stable operation of the valve, greatly extending the service life of the valve and reducing the failure and maintenance costs caused by material problems.

Internal structure: The internal structure is exquisite and compact, including high-precision valve cores, valve seats, and sensitive and reliable driving devices. The valve core and valve seat are precision machined, with extremely high surface flatness and smoothness. The two work closely together to achieve excellent sealing performance when the valve is closed, effectively preventing gas leakage. The driving device is responsible for quickly driving the valve core action and accurately controlling the opening and closing of the valve after receiving the control signal.

（2） Working principle

Normal operation mode: During the normal operation phase of the equipment, the GSOV80 cut-off valve is in the open state, and gas can smoothly pass through the valve and be stably delivered to gas turbines 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, keeping the valve core in the open position to ensure unobstructed gas passage.

Cut off working mechanism: Once the system detects abnormal conditions, such as equipment failure, emergency shutdown instructions, or situations that may endanger safety, the control signal will be immediately transmitted to the driving device of GSOV80. 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.

Product specifications

Pressure parameters: This valve can withstand high working pressures, with a normal working pressure of up to 900 psi (6.2 MPa). Under such pressure conditions, the valve can still perform stable opening and closing operations, ensuring reliable gas cut-off under different pressure conditions and meeting the demand for high-pressure gas control in industrial production.

Traffic performance: According to different application scenarios and system requirements, GSOV80 has good traffic adaptability. Its design can meet the cutting off requirements of gas flow for various types of gas turbines at different power outputs. Whether it is high flow gas cutting for high-power gas turbines operating at full load or low flow control for low-power equipment operating at low load, valves can efficiently complete tasks.

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. It is worth mentioning that 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, providing the possibility to cope with future changes in energy structure and the application of new fuels, enhancing the versatility of the equipment in different fuel environments.

Electrical specifications: The electrical interface design is flexible and adaptable to 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, making it easy to connect with different control systems and power sources, meeting diverse user needs and complex application scenarios.

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.

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.

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.

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.
