MAC solenoid valve 35A-BOO-DDDA-OBA in stock

$221.11

MAC solenoid valve principle: When energized, the electromagnetic force opens the pilot orifice, and the pressure in the upper chamber drops rapidly, creating a pressure difference around the closing element (lower at the top and higher at the bottom). 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 creates a pressure difference around the closing element through the bypass orifice, creating a pressure difference (lower at the bottom and higher at the top). The fluid pressure pushes the closing element downward, closing the valve.

MAC Corporation, with its advanced design and manufacturing technology and numerous advantages, has consistently maintained its leading position in the pneumatic valve manufacturing industry. Before 1980, SMC's pneumatic valves were manufactured using technology purchased from MAC.

The main characteristics of MAC pneumatic valves are: advanced design and manufacturing technology; rapid and reliable valve operation; long service life; low requirements for valve operating conditions, with no special requirements for air cleanliness (Note: Brands such as SMC and FESTO have strict requirements for air cleanliness; please refer to the relevant brand's brochure for usage instructions); in addition, among pneumatic valves with the same flow rate, MAC valves have the smallest external dimensions.

MAC products are highly popular with users due to their superior performance, competitive prices, and excellent service. Statistics show that the company's pneumatic valves have a market share of up to 26% in the United States.

MAC Solenoid Valve Troubleshooting:

MAC solenoid valve not working after power-on (different types of solenoid valves)

Check power wiring for faults → Rewire and reconnect connectors

Check power supply voltage within ± operating range → Adjust to normal range

Coil detached → Resolder

Coil short circuit → Replace coil

Inappropriate operating pressure differential → Adjust pressure differential → or replace with a suitable solenoid valve

High fluid temperature → Replace with a suitable solenoid valve

Impurities causing jamming of the main valve core and moving iron core → Clean; replace seals if damaged and install a filter

High liquid viscosity, high frequency, or expired lifespan → Replace product

Solenoid valve cannot close

Damaged seals on the main valve core or moving iron core → Replace seals

High fluid temperature or viscosity → Replace with a suitable solenoid valve

Impurities entering the solenoid valve core or moving iron core → Clean

Spring expired or deformed → Replace

Clogged throttling orifice/balance hole → Clean promptly Operating frequency too high or lifespan reached → Select a different product or replace the old product.

Other situations:

Internal leakage → Check for damaged seals or improper spring assembly.

External leakage → Loose connections or damaged seals → Tighten screws or replace seals.

Noise during power-on → Loose fasteners on the head; tighten them.

Voltage fluctuations outside the allowable range; adjust the voltage. Impurities or unevenness on the iron core contact surface; clean or replace promptly.

MAC Solenoid Valve Applicability:

1. Media Characteristics

1) Different types of solenoid valves should be selected for gaseous, liquid, or mixed states.

2) Different specifications of products should be used for different media temperatures; otherwise, the coil will burn out, the seals will age, and the service life will be severely affected.

3) Media viscosity, usually below 50 cSt. If it exceeds this value, use a multi-functional solenoid valve when the pipe diameter is greater than 15mm; use a high-viscosity solenoid valve when the pipe diameter is less than 15mm.

4) When the cleanliness of the medium is not high, a backwash filter valve should be installed before the solenoid valve. For low pressure, a direct-acting diaphragm solenoid valve can be used.

5) If the medium flows in a directional manner and backflow is not allowed, a bidirectional flow valve is required.

6) The medium temperature should be selected within the allowable range of the solenoid valve.

MAC solenoid valves currently hold a 26% market share in the United States. 45% of their customers are in packaging machinery, with the remainder in sorting machinery, tire machinery, mining, automotive, electronics, aluminum products, timber, paper, printing, food, and beverage industries.

Its main features:

1. Balanced valve design, response time is unaffected by pressure changes;

2. Anti-jamming valve core protection design to prevent coil burnout;

3. Strong coil suction ensures fast and precise operation;

4. Automatic wear compensation extends valve life;

5. Air isolation extends coil life;

6. Available in various sizes, M5-2 1/2" options;

7. 18-month warranty.
