Compressor Solenoid Valves

Core Coil Technical Data

Coil Model: BDA

Operating Voltage: AC 110/120V, 50/60Hz

Power Consumption: 14.5VA, 100% continuous duty cycle

Valve Body: Forged brass direct-acting 2-position 2-way solenoid valve, capable of opening at zero differential pressure

Certification: CE industrial safety certification

Main Industrial Applications

Intake Load Control: Energize to open the intake valve for compressor loaded air production; cut power to close the intake for unloaded standby and stabilize pipeline air pressure.

Shutdown Blowdown & Pressure Relief: Open instantly when the compressor stops to release residual internal pressure, preventing motor overload burnout during the next startup.

Cooling Circuit Control: Regulate the flow of cooling water and lubricating oil to stabilize the operating temperature of the airend.

Fluid Heating & Boiler Equipment

Suitable for coffee machines, steam boilers, hot water heaters, food cooking equipment:

Automatic on/off control of hot water and saturated steam, compatible with steam up to 180°C.

Automatic water inlet and steam output control for semi-automatic and fully automatic commercial espresso machines.

Industrial Pneumatic & Automated Production Lines

On/off control of compressed air and inert gas (nitrogen, argon) in pneumatic circuits.

Air supply control for packaging machinery, textile equipment, automated fixture cylinders.

High-pressure water circuit switch for laser equipment and industrial washers.

Water Treatment, HVAC & General Machinery

Automatic water flow control for small water purifiers and industrial cleaning machines.

Water circulation control for HVAC heat exchange systems and refrigerant regulation of small refrigeration units.

Liquid medium switching for car wash machines, filling equipment and vending machines.

Working Principle & Product Advantages

Direct-acting structure: No minimum startup pressure required, stable operation under zero/low pressure conditions.

BDA coil highlights: Resists burnout under 100% continuous energization, high temperature resistance, strong tolerance to industrial voltage fluctuations, ideal for 24/7 non-stop equipment.

Brass valve body: Corrosion-resistant against compressed air, water and mildly corrosive fluids, anti-rust design for long industrial service life.

Compatible Working Media

Clean compressed air, cold/hot clean water, saturated steam, non-corrosive lubricating oil, nitrogen and other inert gases.
