Weatherproof IP67 limit switch valve position monitor

Product Overview

Description

weatherproof IP67 limit switch valve position monitor

 

Valve position monitor and limit switch actuator accessories are made of an aluminum die cast body that has been powder coated for protection. 2x 1/2" conduit entries, NAMUR mounting as a standard and fully adjustable spring loaded cams. Corrosion resistance and durable.

 

Valve position indicators/limit switch box are electrical switching devices that mount directly on a valve actuator, or indirectly on a transfer case. They are used in conjunction with a valve positioner.

 

Types of Valve Position Indicators

 

Valve position indicators are used with both rotary actuated valves and linear actuated valves and provide two basic switching options: non-contact and mechanical.

 

Non-contact switches or proximity sensors use inductive or transistor-transistor logic (TTL) and include reed switches.

 

Mechanical switchers are activated by energized arms connected to a moving stem or shaft. There is a mechanical linkage to the actuator.

 

Valve Position Indicator Specifications

 

Valve position indicators differ in terms of display, the number of indicated positions, the number of switches, and pole and throw specifications. Shaft diameter and operating temperature are additional considerations. Most suppliers specify shaft diameter in English units such as inches (in) or metric units such as centimeters (cm). Operating temperature is measured in either degrees Fahrenheit (°F) or degrees Celsius (°C).

 

Display

 

Some valve position indicators display information on a rotating dial or sliding scale. Other products feature a light emitting diode (LED) indicator. Valve position indicators with position transmitters are also available. These devices provide continuous, signal-based information about a valve’s open, closed, or intermediate positions.
