HD -M – SEW6-Poppet Directional Valves Solenoid Actuated

Description

HD -M – SEW6 – Poppet Directional Valves Solenoid Actuated

The HD -M – SEW6 Poppet Directional Valve from THM Huade is a small but effective way to ensure precise and leak-free control of fluids in high-pressure systems. Engineered with up-to-date features and strong design, this valve works well, is easy to fix, and can be trusted to do its job, so it’s perfect for many kinds of industrial jobs.

The valve can withstand 630 bar of pressure and flows 25 L of fluid per minute, and it is solenoid actuated for smooth operation even after long periods of pressure. This product fits on a sub-plate and meets the standards of DIN 24 340 Form A, ISO 4401, and CETOP-RP 121H, making it easy to use in any hydraulic setup.

Types of HD -M – SEW6 Poppet Valves

The HD -M – SEW6 valve can be set up in different ways to fit different needs.

1. 2/2 Way Poppet Valve:

This type has either an open or closed option, which makes it great for turning things on and off in basic flow control situations.

2. 3/2 Way Poppet Valve:

They help direct flow in the circuit and are very helpful in systems that need to switch or empty parts at different stages.

3. Normally Closed Valves:

The solenoid prevents fluid from flowing until it is energized. This makes it suitable for use where safety is very important.

4. Normally Open Valves:

These valves are open by default and close when powered, which is useful when stopping the flow is needed just occasionally.

5. Single Solenoid Operation:

Good for basic directional control using either manual or spring return options.

6. Double Solenoid Operation:

Allows switching in both directions for better control over the system.

Working Principle

The HD -M – SEW6 poppet directional valve uses a direct solenoid to control its movements. A poppet element is placed inside the valve between where the air enters and exits. A magnetic field is created by the energized solenoid coil, which pulls the plunger. When you press the plunger, it makes the poppet move to manage the flow of the fluid.

The valve’s closed port is designed to be leak free, preventing any internal leakage when the valve is not in use. For this reason, the use of pneumatic technology is useful in manufacturing, injection molding, and heavy-duty equipment that require accuracy and cleanliness.

The air-gap DC solenoid is designed so that the coil can be removed and replaced or checked without opening the pressure-tight valve chamber. This also helps you save time and keep the system safe. The solenoid coil can rotate by 90 degrees, which makes it easier to fit in tight or difficult areas.

Even if the system puts pressure on the valve for a long time, it still ensures smooth and reliable switching. This is perfect for systems that start and stop often, as it ensures the system will start reliably every time.

Features and Benefits

1. Leak-Free Operation: Since there is no leakage in the off-state, the closed port design is perfect for important applications.
2. Reliable Under Pressure: Switching will still happen even if the system has been idle for a long time with full pressure.
3. Flexible Installation: The solenoid coil can be turned 90° to fit into smaller areas.
4. Maintenance-Friendly: You can take out the coil without opening the pressure chamber, which makes servicing much easier.
5. Manual Override: Should there be a power outage or emergency, the hand override can be used to control the lift.
6. Individual Electrical Connection: Enables convenient and error-free wiring.
7. Global Compatibility: Porting and mounting are done according to the standards set by DIN, ISO, and CETOP.

Maintenance Tips

For the HD -M – SEW6 poppet valve to last and function well, regular maintenance is required. Here are some expert tips:

1. Visual Inspection: Check the valve body often for any cracks, signs of corrosion, or leaks. Address any abnormalities immediately.
2. Clean Connections: Always keep the solenoid terminals and electrical connectors free from moisture and dirt. If moisture or debris get into the area, it could cause electrical problems or loss of signals.
3. Cycle Testing: Every so often, control the valve (turn it on/off) to make sure it is working correctly. This is most important for valves that are not used for a long time.
4. Monitor Fluid Quality: Choose hydraulic oil that has been cleaned and filtered. When fluids are contaminated, the internal parts can wear and the poppet might stick.
5. Coil Care: Before you replace the solenoid coil, make sure the system is not receiving power. With the removable coil, you can access the hydraulic system without having to open the chamber.
6. Pressure Checks: Check the system pressure from time to time to see if it remains below the limit of 630 bar. If the limit is surpassed, the valve may break down prematurely.
