New Original FESTO 150683 EV‑20‑4 Pneumatic Diaphragm Clamping Module
Product Overview
FESTO EV‑20‑4, part number 150683, is a compact single‑acting diaphragm‑type clamping module belonging to the EV series. It is a flat rodless pneumatic actuator driven by compressed air, featuring a circular diaphragm working surface of 20 mm diameter and 4 mm effective strokeFesto. When supplied with compressed air, the flexible diaphragm expands axially to generate clamping force against workpieces or fixtures; internal mechanical reset returns the diaphragm to its original position once air pressure is removed. This fully‑sealed low‑profile module is widely used for workpiece clamping, positioning and holding in automated assembly jigs, test fixtures, packaging machinery, and small‑batch processing equipment. It fits installation scenarios with extremely limited vertical mounting space and can operate in dusty industrial environments费斯托.
Main Functions
- Pneumatic workpiece clamping: Generates axial clamping force under compressed air pressure to hold flat workpieces against a fixed stop.
- Automatic reset: Built‑in return mechanism retracts the diaphragm when air supply is cut off, releasing clamped parts automatically.
- Short‑stroke linear actuation: Delivers 4 mm working stroke for low‑travel clamping tasks.
- Hermetic sealed operation: Internal components are fully enclosed to resist dust and minor workshop contamination.
- Flexible mounting: Supports any installation orientation, fixed via through‑holes on the housing base.
- Compact fixture integration: Flat body design allows embedding inside compact jigs without occupying excessive vertical space.
- Stable holding performance: Uniform force distribution across circular diaphragm surface reduces local stress on thin‑wall workpieces.
- Pass‑through pneumatic control: Controlled by external solenoid valves for automated clamping‑release cycles.
Technical Characteristics
- Single‑acting operating principle, mechanical spring return without secondary air exhaust port.
- Housing material: Die‑cast aluminium alloy; diaphragm material: TPE‑U polyurethane elastomerFesto.
- Fully sealed construction, no sliding piston rods, minimizing wear and particle generation.
- Conforms to RoHS requirements and VDMA 24364‑B1/B2‑L LABS‑PWIS standards, suitable for painting‑industry automation linesFesto.
- M3 internal thread for pneumatic connection.
- No copper or PTFE‑containing materials inside the assembly.
- Compatible with filtered compressed air per ISO 8573‑1:2010 [7:-:-].
- Light‑weight structure for fixture platforms with low‑load requirements.
