What is NAMUR type solenoid valve?
NAMUR solenoid valve definition NAMUR solenoid valves are used to control media flow. The valve’s electric solenoid opens or closes the valve by controlling the amount of air via a pilot to the pneumatic actuator. The solenoid and actuator work in tandem to control flow speed, flow amount, and flow direction.
What is NAMUR interface?
The ROSS® NAMUR Interface Series is a compact inline ported valve designed to be mounted directly to a pneumatic actuator, eliminating the need for plumbing between the valve and actuator. This 5-way, 2 position valve has ¼” ports located in the valve body offering a Cv of 1.3.
Are all solenoid valves the same?
A wide range of solenoid valve types are available depending on your specific application requirements. The various functions of a solenoid valve depend on the type of valve you have, and the operation you need the valve to perform.
What is NAMUR 43?
NAMUR NE43 is a standard used to define the operating AO-LL and AO-UL values. Similar to the Standard Analog Output Signal, NAMUR NE43 compliant transmitters are designed to output signals greater than the 4 to 20 mA “Base” signal, allowing for a small amount of Signal Saturation.
What is NAMUR full form?
User Association of Automation Technology in Process Industries (NAMUR) (German: Interessengemeinschaft Automatisierungstechnik der Prozessindustrie), established in 1949, is an international association for users of automation technology and digitalization in the process industries with its headquarters in Leverkusen.
How do I choose a solenoid valve?
Solenoid valve selection guide
- Important Information. These are the most important guidelines when selecting a solenoid valve.
- Important Parameters.
- Principle of operation.
- Circuit function.
- Pipe diameter and thread type.
- Orifice, Kv-value and flow rate.
- Medium (determines the choice of materials)
- Pressure.
What type of solenoid valve do I need?
To determine the optimal size for your solenoid valve, you need to know the flow rate, which allows you to determine the flow factor (kv). The flow factor is a theoretical value that indicates the volume of water at room temperature that flows through the solenoid valve with a pressure drop of 1 bar for one minute.
How does a Namur sensor work?
Answer: A NAMUR sensor is a 2-wire proximity sensor that is usually powered by 8 VDC. When the sensor detects the target, the current flow through the sensor drops to less than 1.2 mA. When the target moves away from the sensor and is not detected, the current flow increases to above 2.1 mA.
