Diaphragm Type Remote Control Float Valve

Operation
Long Life
Diaphragm Type Remote Control Float Valve is a hydraulically operated water level control valve designed to automatically maintain the required water level in tanks, reservoirs, water towers and water supply systems. The valve uses a float pilot valve and diaphragm-operated main valve. When the water level reaches the preset level, the float pilot closes the control circuit and the main valve closes to stop water supply. When the water level falls, the float pilot opens the control circuit and the main valve opens to refill the tank.

Frequently Ask Questions
It is a hydraulic control valve that automatically controls the water level in a tank or reservoir using a float pilot valve and diaphragm-operated main valve.
No. A standard 100X diaphragm remote-control float valve operates hydraulically using the pipeline water pressure and float pilot mechanism.
The float rises and closes the float pilot valve. This increases pressure in the control chamber and causes the main diaphragm valve to close, stopping the incoming water.
The float falls and opens the pilot circuit, reducing control-chamber pressure and allowing the main valve to open and refill the tank.
The float arrangement should be positioned according to the required tank water level and available installation space so that it can accurately sense the required level.
Yes. Published 100X documentation states that the valve can be installed according to the tank height and available working space, subject to the manufacturer's installation requirements.
The float detects the water level. When the level reaches the preset point, it controls the hydraulic circuit to close the main valve. When the level falls, the main valve opens and allows the tank to refill.
The Diaphragm Remote Control Float Valve uses a hydraulic float-pilot arrangement, while an Electric Remote Control Float Valve adds electrical/solenoid control for remote operation.
Yes. Its primary function is automatic water-level control, so the valve closes when the preset water level is reached.
No. The standard hydraulic diaphragm design does not require an external electrical power supply.
Yes. Published 100X documentation states that the valve can be installed according to the tank height and available working space, subject to the manufacturer's installation requirements.
Yes. Water towers are one of the principal applications of diaphragm-type remote-control float valves.
