This Exhaust Valve Sheet is a precision-engineered replacement component designed for Edwards RV series vacuum pumps, including the RV3, RV5, RV8, and RV12 models. As a critical internal part of the pump's exhaust mechanism, it ensures the efficient and sealed expulsion of gases. A worn or damaged exhaust valve sheet is a common cause of performance degradation in these oil-sealed rotary vane vacuum pumps.
This OEM-quality replacement part is manufactured to meet strict original equipment specifications, guaranteeing a perfect fit and reliable operation. It is an essential item for the routine maintenance and overhaul of these industry-standard pumps, helping to restore and maintain their specified ultimate vacuum pressure (e.g., 2.0 x 10⁻³ mbar for high vacuum mode) and pumping speed.
Precision Fit: Manufactured to exact Edwards OEM dimensions and tolerances for a perfect fit and seamless operation within RV3, RV5, RV8, and RV12 vacuum pumps.
Restored Pump Performance: Replaces worn or damaged valve sheets to help the pump achieve its optimal ultimate vacuum pressure and maintain consistent pumping speed, addressing issues like the inability to reach base pressure.
Durable Construction: Made from high-quality materials designed to withstand the continuous mechanical impact and chemical environment inside the pump's oil reservoir, ensuring a long service life.
Prevents Performance Issues: A properly functioning exhaust valve is crucial for maintaining the pump's efficiency in handling water vapor and other gases, which is a key feature of the RV series.
Easy Maintenance: This part is a key component in routine pump overhaul and maintenance kits, allowing for straightforward replacement by a qualified technician to resolve common problems like vacuum degradation and excessive noise.
