What is the difference between a direct acting solenoid valve and a solenoid-pilot operated valve?







In a direct acting valve, the main body or poppet is moved using magnetic force generated by the electrical coil to shift the valve. In a solenoid-pilot operated valve, the main body or plunger is moved using force developed from the available pilot pressure. The coil in this case is used to control the pilot for the pilot piston.

Can Versa valves be used in a vacuum service application?







Yes, many Versa valves can be used in vacuum service, depending on the specific type of vacuum setting or environment. Most common are manually operated, direct solenoid and remote piloted solenoid-pilot valve.

Why can’t I reverse flow through your V Series valves?







Reversing the flow through a V&T series valve may result in the valve not functioning correctly because the internal seals could be damaged. Please see “The Anti-Extrusion Principal.” Please note there may be options or other products that may be right for your application. Contact Versa’s friendly expert Technical Sales team for assistance in recommendations for your specific application.

What is the advantage of a solenoid-pilot design over that of a direct acting design?







The advantages of the solenoid-pilot design are high flow capability, reliability and low power consumption. The disadvantage is that it requires a minimum pilot pressure to shift the valve plunger. The advantage of a direct acting solenoid is that there is no minimum pressure requirement. The disadvantages are limited flow capability and high power consumption.

What is a “solenoid-pilot” design?







A solenoid-pilot directional control valve utilizes a combination of a direct acting solenoid and a pilot valve. The solenoid direct acting valve controls the flow of a pressured media going to the pilot valve. The pressurized pilot media pushes on the pilot piston which creates a force (F=P x A). That force is used to move the plunger in the pilot valve. Flow control occurs via the configuration of the plunger. The action of moving the plunger controls the flow of the media. The advantages of the solenoid-pilot design are high flow capability, high reliability, low power consumption and simplicity of piping/installation as pilot lines are integral to the valve. The disadvantage is that it requires a minimum pressure to shift the plunger.

What is a direct acting solenoid?







Direct acting solenoid valves are used to control the flow of fluid and gas media. The most common types of flow control are opening, closing, selecting different media or diverting a media. A direct acting solenoid flow control valves shifts via an electric coil. When energized, it creates a magnetic field that moves a metal poppet. The direct action of energizing and de-energizing the solenoid controls the flow of the media, turning it on and off. The advantage of a direct acting solenoid is that there is no minimum pressure requirement. The disadvantages are limited flow capability and high power consumption.
