SV65B Vacuum pump Exhaust valve sheet for Leybold SV series

Product Specification

Product Overview

This Exhaust Valve Sheet is a precision-engineered replacement part designed specifically for Leybold Sogevac SV Series vacuum pumps, including the SV65B model. As a critical component within the pump's exhaust system, this valve sheet is responsible for ensuring the one-way flow of gases out of the pump chamber, preventing backstreaming and maintaining the pump's ultimate vacuum pressure.

A worn or damaged exhaust valve sheet is a common cause of performance loss in oil-sealed rotary vane vacuum pumps. This OEM-quality replacement part helps restore your Leybold pump to its original specifications, ensuring efficient and reliable operation in demanding industrial and laboratory applications.

Key Features & Benefits

• Precision Fit: Manufactured to exact Leybold OEM dimensions and tolerances for a perfect fit and seamless operation within SV series pumps, including the SV65B.

• Restored Pump Performance: Replaces worn valve sheets to help the pump achieve its specified ultimate vacuum pressure (e.g., 0.5 mbar for SV65B without gas ballast) and maintain consistent pumping speed.

• 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 Oil Backstreaming: A properly functioning exhaust valve is crucial for preventing oil and vapor from flowing back into the pump chamber and the vacuum system, protecting your process.

• Easy Maintenance: This part is a key component in routine pump overhaul and maintenance kits, allowing for straightforward replacement by a qualified technician.

Compatibility Information

This exhaust valve sheet is designed as a direct replacement for Leybold Sogevac SV Series vacuum pumps.

It is confirmed to be compatible with the SV65B model and is also suitable for other SV series pumps with the same valve assembly, such as the SV40B and SV100B.

Verification is Crucial: Always verify your pump's full model number and the existing part specifications before purchase. Cross-reference with your pump's parts list for confirmation.

Symptoms of a Failing Exhaust Valve Sheet

Be aware of these common signs that may indicate the need for a valve sheet replacement:

• Poor Ultimate Vacuum: The pump cannot reach its base pressure even after adequate pumping time.

• Slow Pumping Speed: The time required to evacuate a vessel increases significantly.

• Oil Backstreaming: Visible oil mist or contamination is present in the vacuum line or chamber.

• Increased Noise: Unusual "chattering" or knocking sounds may emanate from the pump's exhaust assembly.

• High Exhaust Pressure: Issues related to the exhaust pressure can be a symptom of valve problems.
