ANTI-SYPHON VALVE LT-1

The Anti-Syphon Valve LT-1 is designed to fit on Above Ground Fuel Storage Tanks to prevent accidental loss of product through syphoning downstream of the suction line.

The Anti-Syphon valve uses a patented balancing diaphragm design to maintain a low cracking pressure almost una ected by the change of product level.

This combined with its engineered flow path geometry ensure high flow efficiency for suction pump and dispensing equipment, and prevents suction line vapour lock.

Specifications:

• Port size: G3" / NPT3"
• Hydrostatic head: 0–4.6m  /  0–15ft
• Cracking pressure: 0.07–0.14bar  /  1.0–2.0 psi
• Internal relief: 1.2–2.5bar  /  17–36psi
