Description

Xiechang® G3/4″ DCF-F-2L Explosion-Proof Right-Angle Pulse Jet Valve

The Xiechang® explosion-proof right-angle pulse valve is a high-performance actuator specifically engineered for hazardous dust collection environments. As a critical baghouse pulse valve component, it features a 90-degree configuration and a robust flameproof (Ex d) pilot, ensuring precise, high-velocity air delivery for filter cleaning where safety is non-negotiable. Its compact G3/4″ design is ideal for space-constrained manifolds.

Technical Guide & FAQ

▶ 1. What is an Ex-Proof Right-Angle Pulse Valve?

It is a specialized safety version of the standard baghouse pulse valve. The “Right-Angle” refers to the 90° layout between the air inlet and outlet. This Xiechang® model integrates a flameproof enclosure for the solenoid pilot, preventing internal electrical sparks from triggering an explosion in the surrounding hazardous environment.

▶ 2. What is the working principle of the Ex-Proof Right-Angle Pulse Valve?

The valve operates on a pressure differential principle. In the standby state, air pressure fills the rear chamber to keep the diaphragm sealed. When the ex-proof pilot triggers, it vents the rear chamber pressure instantly. The diaphragm lifts, allowing a massive blast of compressed air to discharge through the right-angle outlet into the filter bags.

▶ 3. What are the advantages of the Ex-Proof Right-Angle Pulse Valve?

Key benefits include Superior Safety Compliance (Ex d IIC T6), a Compact Form Factor for restricted spaces, and high-speed response. The high-quality diaphragm ensures stability over 1 million pulses, significantly reducing maintenance downtime in explosive zones.

▶ 4. What are the defects of the Ex-Proof Right-Angle Pulse Valve?

Due to the heavy-duty ex-proof casting, the initial cost is higher than standard valves. Also, the G3/4″ right-angle layout requires precise piping alignment during installation to ensure optimal airflow and prevent mechanical stress on the joints.

▶ 5. What are the application scenarios?

Commonly used in petrochemical refineries, coal processing, flour mills, and wood manufacturing—anywhere where combustible dust or gases create a potential explosion risk during filtration systems requiring a reliable baghouse pulse valve.
