AIRTAC analyzes the principle of solenoid valve
AIRTAC pilot solenoid valve:
Features: high upper limit of fluid pressure range , can be installed arbitrarily (needs to be customized) but must meet the fluid pressure difference conditions.
Principle: When energized, the electromagnetic force opens the pilot hole, and the pressure in the upper chamber drops rapidly, forming an upper, lower, and higher pressure difference around the closing member. The fluid pressure pushes the closing member to move upward, and the valve opens;when the power is off, the spring force closes the pilot hole, and the inlet pressure quickly passes through the bypass hole and forms a pressure difference between the lower and upper chambers around the closing member. The fluid pressure pushes the closing member Move down to close the valve.
Solenoid valve has the following characteristics: valve structure and material The differences and principles are divided into six subcategories: direct-acting diaphragm structure, step-direct-acting diaphragm structure, pilot diaphragm structure, direct-acting piston structure, step-direct-acting piston structure, and pilot piston structure.
AIRTAC direct-acting solenoid valve:
Features: It can work normally under vacuum, negative pressure and zero pressure, but the diameter generally does not exceed 25mm.
Principle: When energized, the electromagnetic coil generates electromagnetic The force lifts the closing part from the valve seat and the valve opens;when the power is turned off, the electromagnetic force disappears and the spring presses the closing part against the valve seat and the valve closes.
