Constant water level valve, vacuum breaker, check valve, check valve LP-9HN type constant water level valve (for water, with adjustment mechanism for general use)
Major features
- Equipped with a flow rate adjustment mechanism and a needle for adjusting the valve closing time.
- Measures against red water: Screw-in type = main body made of bronze + pipe end core can be incorporated
- Since the passage to the pilot pipe is a bypass passage, there is no effect of intermittent water supply from the ball tap due to waves, and quiet and stable water supply is provided.

Frequently Asked Questions and Explanations
What kind of failure (complaint) does the constant water level valve have?
Please check the details.
Why do you use solenoid valves and ball taps together for pilot piping?
When using a solenoid valve, the water level is detected by the liquid level switch, and the main valve is opened and closed by the operation of the pilot solenoid valve to control the water level.
Is the flow rate adjustment mechanism of the constant water level valve a constant flow valve?
It is not a constant flow valve. The purpose is to regulate the maximum flow rate to prevent the water pressure drop in the water pipes during the daytime when tap water is in high demand.
