Features of ASCO Solenoid Valves (USA): High upper limit of fluid pressure range, can be installed arbitrarily (customization required), but must meet fluid differential pressure conditions.

2. Solenoid valves are divided into six subcategories based on differences in valve structure, materials, and operating principles: direct-acting diaphragm structure, step-direct-acting diaphragm structure, pilot-operated diaphragm structure, direct-acting piston structure, step-direct-acting piston structure, and pilot-operated piston structure.

3. Solenoid valves are classified by function: water solenoid valves, steam solenoid valves, refrigeration solenoid valves, cryogenic solenoid valves, gas solenoid valves, fire-fighting solenoid valves, ammonia solenoid valves, gas solenoid valves, liquid solenoid valves, miniature solenoid valves, pulse solenoid valves, hydraulic solenoid valves, normally open solenoid valves, oil solenoid valves, DC solenoid valves, high-pressure solenoid valves, explosion-proof solenoid valves, etc. Environmental Requirements for ASCO Solenoid Valves (USA):

1) The maximum and minimum ambient temperatures should be within acceptable ranges.

2) In environments with high relative humidity or exposure to water droplets or rain, waterproof solenoid valves should be selected.

3) In environments with frequent vibration, bumps, and impacts, special types should be selected, such as marine solenoid valves.

4) In corrosive or explosive environments, corrosion-resistant types should be selected based on safety requirements.

5) If space is limited, multi-functional solenoid valves should be selected, as they eliminate the need for bypasses and three manual valves and facilitate online maintenance.

Power Supply Requirements for ASCO Solenoid Valves (USA):

1) Select AC or DC solenoid valves according to the type of power supply. Generally, AC power is more readily available.

2) For voltage specifications, AC220V and DC24V should be preferred.

3) Power supply voltage fluctuations are typically +10% to -15% for AC and ±10% for DC. If these fluctuations exceed the tolerance, voltage stabilization measures must be taken.

4) The rated current and power consumption should be selected according to the power supply capacity. It should be noted that the VA value is high during AC startup; therefore, indirect-operated solenoid valves should be preferred when capacity is insufficient.

Main Classifications of ASCO Solenoid Valves

Three Major Categories

(1) Direct-Acting Solenoid Valve:

Principle: When energized, the electromagnetic coil generates electromagnetic force to lift the closing element from the valve seat, opening the valve; when de-energized, the electromagnetic force disappears, and the spring presses the closing element onto the valve seat, closing the valve.

Features: Can work normally under vacuum, negative pressure, and zero pressure, but the nominal diameter generally does not exceed 25mm.

(2) Step-by-Step Direct-Acting Solenoid Valve:

Principle: It combines direct-acting and pilot-operated principles. When there is no pressure difference between the inlet and outlet, after energization, the electromagnetic force directly lifts the pilot valve and the main valve closing element sequentially upwards, opening the valve. When the inlet and outlet reach the starting pressure difference, after energization, the electromagnetic force pilots the small valve, the pressure in the lower chamber of the main valve rises, and the pressure in the upper chamber drops, thus using the pressure difference to push the main valve upwards; when de-energized, the pilot valve uses spring force or medium pressure to push the closing element downwards, closing the valve. Features: Reliable operation even at zero differential pressure, vacuum, or high pressure, but requires higher power and must be installed horizontally.

(3) Pilot-operated solenoid valve:

Principle: When energized, the electromagnetic force opens the pilot orifice, causing the pressure in the upper chamber to drop rapidly, creating a pressure differential around the closing element (higher at the bottom and lower at the top). The fluid pressure pushes the closing element upward, opening the valve. When de-energized, the spring force closes the pilot orifice, and the inlet pressure quickly passes through the bypass orifice, creating a pressure differential around the closing element (lower at the bottom and higher at the top). The fluid pressure pushes the closing element downward, closing the valve.
