HFS-25 1″/DN25 SPDT Water Switch by YWBLWH Stainless Steel Control

Description

Product Overview

The HFS-25 1″/DN25 SPDT water switch is engineered to provide accurate flow monitoring across a broad spectrum of industrial and commercial applications. Built with high‑grade stainless steel, the housing resists corrosion from water, ethylene diluents, glycols, and other non‑copper‑corrosive liquids, ensuring a long service life even in harsh environments. The device features a paddle‑type flow sensor that moves with the fluid, mechanically actuating a microswitch to open or close the SPDT contacts. Electrical specifications cover a wide voltage range of 6‑380V, making the switch compatible with most control panels and PLC systems. Dimensions of 3.35 × 2.56 × 4.92 inches and a weight of 1.15 lb provide a compact footprint that fits easily into standard pipe assemblies. The product carries the model number YWBL‑WHy7wxqc2410 and is manufactured by YWBL‑WH, a reputable supplier known for precision hydraulic components.

Usage

This water switch excels in water treatment plants where precise flow regulation is critical to maintain water quality and system efficiency. It is equally suitable for central air‑conditioning systems, where it monitors chilled water circulation to prevent pump cavitation and ensure balanced cooling loads. In industrial cooling units, the switch safeguards against overheating by triggering alarms or shutdowns when flow drops below a preset threshold. Fire protection systems also benefit from the reliable detection capabilities, as the switch can activate fire suppression pumps automatically when water flow is detected. The SPDT configuration allows the switch to interlock with other safety circuits, providing a fail‑safe mechanism that isolates power or initiates backup systems when abnormal flow conditions occur. Installation is straightforward: the paddle aligns with the flow direction, the mounting brackets secure the unit to the pipe, and the electrical leads connect to the control panel without the need for additional adapters.

FAQ

What types of fluids can the HFS-25 switch monitor?

The switch is suitable for water, ethylene diluents, glycols, and other liquids that do not corrode copper. Its stainless‑steel construction protects against chemical attack, making it ideal for a variety of non‑corrosive fluids.

How is the flow threshold adjusted?

The paddle inside the switch can be rotated to set the desired flow level. Turning the adjustment screw changes the position at which the paddle moves enough to actuate the microswitch, allowing precise calibration for each installation.

Can the switch be used in fire protection systems?

Yes. The HFS-25 is commonly employed in fire suppression setups to detect water flow and trigger pump activation or alarm signals, ensuring rapid response during emergencies.

What is the recommended installation orientation?

The paddle must be aligned with the direction of fluid flow. Install the switch vertically or horizontally as long as the flow direction matches the paddle orientation, and secure the unit with the provided mounting brackets.

Is there a warranty or support service?

All units come with a manufacturer warranty covering material and workmanship defects. Our technical support team is available to assist with installation, calibration, and troubleshooting throughout the product’s lifecycle.
