Butterfly Valve with Limit Switch

As factories and their processes become increasingly complex and rely more on real-time system feedback, many customers are increasingly demanding electrical feedback for both manual and automatic valves. Each valve is different, so Waits valve modification Butterfly Valve with Limit Switch will provide customized services based on sample valves and required switch boxes.

Advantage

Low cost valve position indication product

Hot melt adhesive baking powder coating shell

2-channel single pole double throw (SPDT) mechanical switch, rated current 16 amperes

You can indicate the on/off status through a clearly visible spherical indicator light

The cam is easy to adjust and the on-site calibration is simple. No tools required.

Two 1/2-inch NPT conduit interfaces

Butterfly Valve with Limit Switch is a manual limit switch suitable for up to 8-inch ball valves and butterfly valves. The valve complies with the ISO5211 standard, meets the NEMA 4X rating, and is equipped with a built-in locking device. Standard SPDT 10 ampere @ 120VAC limit switch.

A limit switch is an electromechanical device that mechanically connects an actuator to an electrical switch. A limit switch is a control device that is powered by the movement of an object. In short, limit switches can monitor the movement of other objects.

Mechanical limit switches have high accuracy and repeatability. Contact sensors are used to detect the presence and position of objects in industrial operations.

The types of limit switches are usually divided into four categories: whisker type, roller type, lever type, and plunger type. They are configured as normally open, normally closed, or both. In some applications, limit switches have been replaced by proximity sensors.

When an object comes into contact with the limit switch lever (or plunger), the lever will move a predetermined distance until the contact is activated. Overtravel refers to the lever moving beyond the predetermined travel distance. main points.
