Product Description
The Excess Flow Valves manufactured and supplied by us are designed to stop when a sudden flow surge occurs. They automatically reset when pressure is restored. Also known as surge preventer, earthquake valve, shutdown valve, they are single line in which pressurized gas or liquid flows in either directions. Every valve has its own closing flow rate based on different conditions. Excess Flow Valves can be used for different types of fluids & processes like butane, nitrogen air, anhydrous ammonia, LP gas, water & various other. Moreover, they are available in a different variety of pressure materials, flange designs as well as end connections as per the customers requirements.

FAQs of Excess Flow Valves:
Q: How do excess flow valves provide safety in industrial applications?
A: Excess flow valves are essential for safety as they instantly shut off media flow when abnormal flow rates are detected, minimizing the risk of leaks or system failures. They are particularly effective for environments handling gases, liquids, or chemicals.
Q: What is the recommended process for installing these valves?
A: Installation is straightforwardthese valves can be mounted either horizontally or vertically using the female threaded end connections. Always ensure the flow direction matches the uni-directional marking, and use appropriate PTFE or gaskets for sealing.
Q: When should the shut-off differential be set or adjusted?
A: The shut-off differential should be configured during installation or system maintenance, tailored to the specific flow requirements of your application. This customization ensures optimal performance and safety according to process demands.
Q: Where are these excess flow valves commonly used?
A: They are frequently installed in gas distribution pipelines, petroleum processing plants, chemical industries, and similar sectors across India where safety and rapid response to flow anomalies are crucial.
Q: What are the benefits of using stainless steel for the spring and disc components?
A: Stainless steel offers excellent resilience, corrosion resistance, and longevity, which enhance the valves sensitivity and reliability even in harsh or corrosive environments.
Q: How does the valve maintain a zero leakage rate?
A: The valves utilize precision sealing materials such as PTFE or gaskets, coupled with a well-engineered ball or piston design, ensuring a tight seal and preventing media leakage during operation.
