English Introduction for Busch Exhaust Valve With Gaskets, Part No. 916529297

1. Basic Product Overview

2. Material & Core Technical Parameters

• Valve body material: High-strength nylon engineering plastic, excellent heat resistance, oil resistance and fatigue resistance for long-cycle continuous operation

• Supporting accessories: Integrated dedicated rubber sealing gaskets, no extra gaskets needed during on-site replacement

• Net weight: 0.2 kg per piece

• Unit: Each (EA)

• Customs tariff code: 8414.90.90

3. Compatible Vacuum Pump Models

4. Working Principle & Functional Advantages

1. One-way air exhaust control: Automatically opens during pump compression stroke to discharge exhaust gas, and closes tightly instantly in the suction stroke to prevent gas backflow and vacuum degree loss inside the pump chamber, stabilizing ultimate vacuum performance consistently.

2. Pre-installed gaskets: Comes with matched gaskets as a complete kit, eliminating separate gasket procurement and cutting maintenance downtime greatly.

3. OEM original matching: Strictly follows Busch original design dimension standards, perfect fit without modification, effectively avoids air leakage at the exhaust port after assembly.

4. Durable construction: Wear-resistant nylon valve body adapts to long-term high-temperature and oil-laden working conditions inside oil-lubricated rotary vane pumps, reducing frequent part replacement frequency and lowering total operation cost.

5. Application Scenarios

• Food packaging & thermoforming

• Pharmaceutical manufacturing & medical equipment

• Woodworking CNC machining

• Plastic extrusion & thermoforming

• Electronic component packaging, semiconductor processing

• Central vacuum systems for general factory automation

6. Installation & After-Sales Notes

1. Direct plug-and-play replacement for old failed exhaust valves; no rework or trimming required for installation ports.

2. Genuine Busch spare parts carry official OEM quality warranty, stable interchangeability guaranteed.

3. Regular inspection is recommended during routine pump maintenance; replace the whole valve & gasket set once valve flapper deformation, aging gasket leakage or backflow occurs.
