As a trusted valve distributor and valve stockist, we supply genuine Bifold solenoid valves to support industrial automation systems, ensuring performance reliability and compliance with hazardous area requirements.

What is a Direct Acting Pneumatic Solenoid Valve?

A direct acting solenoid valve is an electrically operated valve that directly controls the opening and closing of a flow path without relying on differential pressure. When electrical power is applied to the solenoid coil, the plunger moves immediately, allowing or blocking airflow.

This design ensures:

Fast response time
Reliable switching at low or zero pressure
Consistent performance in instrument air systems
Stable operation in safety-critical applications

Unlike pilot-operated valves, direct acting solenoid valves are ideal for applications where pressure conditions vary or where quick actuation is essential.

Key Features and Benefits

1. 316 Stainless Steel Construction

The valve body is manufactured from 316 stainless steel, providing:

Excellent corrosion resistance
Compatibility with harsh industrial environments
Long service life in offshore and chemical plants
Resistance to moisture, salt spray, and corrosive gases

This makes it particularly suitable for oil & gas, marine, and petrochemical applications.

2. Direct Acting Operation

Direct acting design ensures immediate response when energized.

Advantages include:

Reliable switching without requiring minimum pressure
Fast response for safety shutdown systems
Stable performance in low-pressure instrument air circuits

This feature is especially important in emergency shutdown (ESD) and safety instrumented systems (SIS).

3. 3 Way, 2 Position Configuration

The 3/2 configuration provides versatile functionality:

Air supply control
Venting operation
Actuator switching
Pneumatic logic circuits

This configuration allows one port to supply air, one to exhaust, and one to connect to the actuator or system component.

4. Explosion-Proof (Ex d) Certification

The Ex d rating indicates that the solenoid valve is suitable for hazardous areas where explosive gases may be present.

Benefits include:

Safe operation in Zone 1 or Zone 2 environments (depending on certification)
Compliance with industrial safety standards
Reduced ignition risk in volatile atmospheres

This makes the valve ideal for refineries, offshore platforms, and gas processing facilities.

5. 24VDC Low Power Consumption

Operating at 24VDC with only 5.7W power consumption, the valve ensures:

Energy-efficient operation
Compatibility with industrial control systems
Reduced heat generation
Stable long-term performance

24VDC is widely used in industrial automation and control panels.

6. Cv 0.75 Flow Capacity

With a flow coefficient (Cv) of 0.75, the valve provides adequate flow capacity for:

Pneumatic actuators
Instrument air switching
Pilot control applications
Automation control loops

Proper Cv selection ensures optimal actuator response time and system efficiency.
