Features

• The intake mechanism uses a float structure.
• When water flows, it closes securely, and when negative pressure is generated, air is introduced promptly to prevent backflow caused by reverse siphon action.
• It also uses a spring system that closes the valve before backflow occurs.
• By guiding the intake port connection pipe to the drainage ditch, any potential valve leaks will not pollute the surroundings.
• Additionally, it is equipped with a test cock as standard, allowing you to check the functions of both the check valve and intake valve while the piping is connected.
