herion safety valve quotation

IMI Herion 3/2-Way Solenoid Valves are direct acting, poppet valves that have been designed to operate single and double acting pneumatic actuators. The IMI Herion 24011 Series has been specifically designed for use outdoor, and offer consistently high performance in critical applications. They are SIL 3 rated, offering a life-cycle up to 12 years and are available with various ATEX Classifications for use in Hazardous Areas. Available with Aluminium, Brass or Stainless Steel body variations depending on the application, the 24011 Series is a versatile solenoid valve that offers superior performance and reliability in the most demanding applications.

The 2493230080023050 IMI Herion Pneumatic Safety Valve is a Fail-Safe Safety valve for use on Mechanical Presses and other industrial safety applications. It offers self-monitoring and has a double solenoid valve control system which delivers inherent safety. It has been designed with pneumatic brake and clutch systems in mind, offering and increase in safety and a reduction in downtime.

The main considerations are the sealing form of the valve and the quality sealing form of the seal: soft and hard seals, and soft seals are divided into dynamic and static seals. In terms of the form of the seal, the hard seal is the best, but the processing accuracy is relatively high and the price is relatively high. Most of the solenoid valves on the market are soft seals, while the static seals are more static than dynamic ones. The seals of HERION solenoid valves are static seals, and the seals are made of specially treated rubber. Basically, the number of movements of the spool can be guaranteed from 1 to 3 million times, and the service life is about 8-10 years.

Mainly the processing method of air source interface. Common piping is mainly stainless steel, copper and rubber tube. The interface card is mainly made of stainless steel, copper and plastic. If rubber or plastic interface card is used, the relative use is relatively If it is easier to destroy, there will be a leak, which will cause the valve to malfunction.

The general solenoid valve has gas reset or spring return. If the spring is reset, due to the frequency of the action and the service life, the spring will be invalid, and the reset failure will occur, causing the spool to be out of position and the large valve to be closed or It is open.

Mainly because small particles block the air source interface, resulting in unsmooth airflow, abnormal valve opening, or hard objects jamming the valve core, causing the valve core to fail to operate, or the valve body may have water for a long time, resulting in the valve body. The lubricant is diluted and the valve core is stagnation. This phenomenon is mainly caused by the fact that the filter is not installed before the valve, or the pipe is not cleaned, or the rust is caused by the material of the pipe. Therefore, we recommend adding a NORGREN filter pressure reducing valve before the valve to extend the life of the solenoid valve and reduce the failure rate of the large valve.

Many solenoid valves are now equipped with manual operating devices for operation in an unpowered state or for safety during emergency shutdown. What needs to be noted here is the on-site confirmation type manual operation button. If the person does not confirm the solenoid valve on the spot, it will not start again. However, the common solenoid valve manual operation button should not be touched casually.

Mainly pilot-operated solenoid valves generally require a starting pressure of at least 1 bar. If the pressure of the air supply is too small, the solenoid valve cannot be opened.

Since the solenoid valve has a certain distance from the central control room, if the solenoid valve is not properly selected, the power consumption cannot meet this transmission distance, which will cause the solenoid valve to fail to start normally.
