Description
3/4 Inch Air Pilot Dust Collector Valve – CS Fluid Power PXLA20
The CS Fluid Power PXLA20 is a 3/4" BSP 2/2 way normally closed air-piloted dust collector valve designed for rapid switching of compressed air in industrial dust collection, filter cleaning and pneumatic pulse applications.
Featuring a lightweight anodised aluminium body and nylon-reinforced NBR diaphragm, the PXLA20 provides fast opening and closing with a maximum response time of 50 milliseconds.
The valve is externally controlled through a 1/4" BSP air pilot connection and operates across a pressure range of 0.5 to 9.9 Bar.
Clearance / sale stock – available while stocks last.
Valve Function & Operation
Function: 2/2 way normally closed
Operation: Pneumatic air pilot operated
Pilot connection: 1/4" BSP
Process connection: 3/4" BSP
Media: Compressed air
Minimum operating pressure: 0.5 Bar
Maximum operating pressure: 9.9 Bar
Opening / closing time: 50ms maximum
Mounting position: Any position
The external pneumatic pilot provides rapid diaphragm operation without requiring an electrical solenoid coil on the valve.
Flow & Orifice
Port size: 3/4" BSP
Orifice: 20mm
Kv flow factor: 9.5
The large diaphragm-operated flow path is designed to deliver a rapid pulse of compressed air for dust collector and filter-cleaning systems.
Construction
Body: Anodised aluminium
Tube and internal parts: Stainless steel
Diaphragm / seals: NBR with nylon reinforcement
The reinforced diaphragm construction provides reliable repetitive operation in compressed-air pulse applications.
Pressure & Temperature
Operating pressure: 0.5–9.9 Bar
Maximum media temperature: +60°C
Ambient temperature: +5°C to +60°C
Fast 50ms Switching
The PXLA20 has a maximum opening and closing time of 50 milliseconds, making it particularly suitable for applications requiring a short, high-flow compressed-air pulse.
This fast response is ideal for cleaning filter bags, cartridges and other dust filtration equipment where accumulated material is removed by a sudden reverse pulse of compressed air.
