1. Safety Assurance: The primary purpose of the Slam Shut-off Valve is to enhance safety within gas pipeline and distribution systems. It is installed immediately after the filter and before the regulator, positioning it as a vital safety component.
2. Pressure Regulation: The regulator’s role is to maintain a specific and safe pressure level in the gas pipeline downstream. However, in rare cases, the outlet pressure of the regulator may exceed permissible limits due to various factors, including regulator malfunction, sudden demand spikes, or other anomalies.
3. Immediate Flow Interruption: In the event that the Slam Shut-off Valve senses an outlet pressure exceeding the permissible limits, it responds swiftly and decisively. It closes off the flow of gas downstream immediately, preventing the transmission of excessive pressure throughout the system.
4. Manual Reset: After the Slam Shut-off Valve has closed due to a pressure breach, it does not automatically reopen when the pressure returns to acceptable levels. Manual intervention is required to reactivate the valve. This manual reset ensures that the system is only restored to operation when it is safe to do so.
1. Safety Enhancement: The primary advantage of the Slam Shut-off Valve is the enhancement of safety. It acts as a critical safety measure to prevent gas pressure from reaching dangerous levels within the pipeline. This helps minimize the risk of gas leaks, equipment damage, and potential accidents.
2. Pressure Control: The valve helps maintain optimal pressure levels within the gas pipeline system by shutting off flow when pressure exceeds permissible limits. This contributes to the reliability and longevity of the equipment and piping.
3. Emergency Response: In the event of sudden pressure spikes or anomalies, the Slam Shut-off Valve provides an immediate response, reducing the likelihood of system damage and ensuring that the situation is brought under control promptly.
4. Manual Control: The ability to manually reset the valve after regulator maintenance allows for controlled and safe reactivation of the gas flow. This ensures that gas is only supplied when conditions are within safe operating parameters.
5. Protection of Equipment: By preventing excessive pressure, the Slam Shut-off Valve helps protect downstream equipment and appliances from potential damage caused by high-pressure surges.
