Product Formation

Wafer Butterfly Valve with Supervisory Switch is a fluid control device that integrates a wafer-type butterfly valve and a status monitoring switch. It is mainly used for fluid shut-off, regulation, and remote status monitoring in pipeline systems. Its core design combines the compact structure of the butterfly valve with the signal feedback function of the monitoring switch, and it is widely used in industrial, municipal, and civil fields that require precise control and automated management.

It adopts a wafer type connection, which is clamped and fixed between pipes by flanges on both sides. There is no need for additional flange pairing, saving installation space and cost. The valve body is usually circular and contains a rotatable circular valve plate (butterfly plate) inside. Driven by the valve stem, it can rotate from 0° to 90° to achieve full opening (90°, with low fluid resistance) or full closing (0°, with sealed blocking) actions.

Product Features

The core feature of the Wafer Butterfly Valve with Supervisory Switch lies in the in-depth integration of "the fluid control capability of the wafer-type butterfly valve" and "the state sensing function of the supervisory switch", which combines the advantages of compact structure, precise control and system intelligence. Its features are as follows:

Adopting a "wafer-type" connection, it is directly clamped and fixed by flanges on both sides of the pipeline, without the need for additional matching flanges or welding, saving installation space, especially suitable for pipeline layouts with limited space (such as underground pipe galleries, equipment mezzanines).
The valve body is lightweight (much lighter than the flange-type butterfly valve), reducing transportation and hoisting costs, and at the same time reducing the load on the pipeline system.
Performance: efficient fluid control and high reliability, low flow resistance and high-efficiency circulation (suitable for large flow scenarios), and excellent sealing performance (reducing leakage).
Modular design: The supervisory switch and the valve body can be quickly disassembled (without disassembling the pipeline), and only the switch module needs to be replaced in case of failure.
Simple maintenance requirements: daily maintenance only requires checking the cleanliness of the switch contacts (to avoid poor contact) and valve stem lubrication (grease filling once a year), without professional tools.
