A NAMUR solenoid valve is directly mounted to pneumatic actuator inlet/outlet ports. The function of a NAMUR solenoid valve is to control media flow: the valve itself is controlled by an electric solenoid, which opens or closes the valve, by controlling the amount of air thru a pilot to the pneumatic actuator.
What is NAMUR standard for solenoid valve?
The word, NAMUR, somewhat a misnomer, is an acronym for the User Association of Automation Technology in Process Industries, and serves as a standard for automated valve technology. ... A 3 way solenoid valve typically consists of 1 inlet, 1 outlet, and 1 exhaust port, and 2 seats for fluid control.Sep 14, 2016
What are the two main types of solenoid valve?
There are many different types of solenoid valves available, though direct-acting and pilot-operated valves are the two main categories. When selecting a solenoid valve, it is important answer questions about the application and ensure that you are choosing a suitable valve.Oct 31, 2020
What is a solenoid valve used for?
Solenoid valves are the most frequently used control elements in fluidics. They are commonly used to shut off, release, dose, distribute or mix fluids. For that reason, they are found in many application areas.
How do you classify a solenoid valve?
Solenoid valves are divided into six sub-categories from the differences in valve structure and materials and in principle: direct-acting diaphragm structure, step-by-step direct-acting diaphragm structure, pilot diaphragm structure, direct-acting piston structure, Step-by-step direct-acting piston structure and pilot ...Jun 23, 2020
What does NAMUR mount mean?
NAMUR mount means the solenoid can be mounted directly to valve actuators. Designed for double acting or spring return actuators.
What is NAMUR connection?
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.
