Remote Diaphragm Float Control Valve

This product is a Diaphragm-type Remote Float Control Valve, a hydraulic control valve powered by the pressure of the pipeline medium. It drives the main valve to open and close through the liquid level signal from the matching float assembly, realizing automatic liquid level control for water storage facilities such as water tanks, pools, and water towers. It is suitable for systems including water supply and drainage, fire protection, municipal water services, and industrial storage tanks. It stably maintains the water level of water storage facilities without external power, and features reliable operation and easy maintenance. It is one of the core devices for water supply in high-rise buildings and liquid level management in irrigation systems.

Product Formation

This product is a Remote Diaphragm Float Control Valve—a hydraulically actuated control valve driven by the pressure of the pipeline medium. It actuates the opening and closing of the main valve via liquid level signals transmitted by the accompanying float assembly, thereby enabling automatic liquid level regulation for water storage facilities (including water tanks, reservoirs, and water towers).Designed for integration into water supply and drainage, fire protection, municipal water utility, and industrial storage tank systems, it reliably maintains the water level of storage facilities without reliance on external power sources. Combining the attributes of dependable operation and straightforward maintenance, this valve acts as a core device for water supply in high-rise buildings and liquid level management in irrigation systems.

Product Features

Unpowered Automatic Control

Driven by the pipeline's own water pressure, it achieves automatic liquid level adjustment with the float assembly, eliminating the need for electricity or external power sources. This reduces energy consumption and operation & maintenance costs, and is suitable for unattended scenarios.

Stable and Precise Operation

Adopting a dual-chamber structure and built-in filter screen design, it can buffer hydraulic impact and reduce impurity blockage. Liquid level control is not affected by water pressure fluctuations, with a control accuracy of within ±20mm.

High Durability

The main body is made of ductile iron (with anti-corrosion painted surface), and the diaphragm is made of nylon-reinforced fiber composite material. It is compatible with media such as clean water and softened water, has a wide operating temperature range, and a service life of over 50,000 hours.

Easy Installation and Maintenance

It uses standard flange connections (compatible with standards like GB/ANSI), and key components adopt a modular design, allowing disassembly and maintenance without special tools. The built-in filter screen enables self-cleaning, reducing maintenance frequency.
