How Does an Anti-Siphon Valve Work?
Valve The anti-siphon valve is located on the outlet of the pump. This strategic location works against gravity and prevents draining on the tank. The valve opens when pressure is applied from the pump and then closes airtight at the moment the pump pressure ceases to flow. The anti-siphoning valve will close more tightly when negative drainage occurs. Not only does the anti-siphon valve prevent someone from stealing gas, but it completely shuts out any unwanted contaminants with vacuum-tight sealing (made of thermoplastic) around the tank. The seal is a non-wet u-cup. This isolates the control spring. Settings Relief and inlet settings vary on different anti-siphon valve models. To ensure quality, the consumer will purchase an anti-siphoning valve that is adjustable. The relief setting will be 5 to 100 pressure per square inch. The inlet pressure is set at most to 150 pressure per square inch. To reduce pressure drop during fueling, the anti-siphoning valve will have a big fluoropolym
