PFEIFFER VACUUM AVC 016 PA AVC016PA Product Description

Overview

PFEIFFER VACUUM AVC 016 PA AVC016PA is a bellows-sealed electro-pneumatic angle valve from Pfeiffer Vacuum AVC series for high vacuum systems. PFEIFFER VACUUM AVC 016 PA AVC016PA is DN16 ISO-KF flange type, used for vacuum pipeline on-off control in vacuum pumps, analytical instruments and process vacuum skids. PFEIFFER VACUUM AVC 016 PA AVC016PA integrates position indicator switch and built-in pilot solenoid valve for remote control and valve status feedback.

Features

PFEIFFER VACUUM AVC 016 PA AVC016PA adopts metal bellows feedthrough structure, fully separating vacuum cavity from actuator side and achieving ultra-low leakage rate. It is equipped with PI reed switch position indicator and PV 24V DC pilot solenoid valve, providing valve open/close discrete signal feedback to PLC. The valve body is aluminum housing with FKM sealing, supporting wide vacuum range from 1×10⁻⁸ hPa up to 2000 hPa absolute pressure. PFEIFFER VACUUM AVC 016 PA AVC016PA requires 4000–8000 hPa compressed air supply, with fast 100ms opening and closing time. It can withstand differential pressure 5000 hPa in closing direction and 2000 hPa in opening direction. The bakeout temperature of housing is up to 80℃. PFEIFFER VACUUM AVC 016 PA AVC016PA is compact and lightweight at 0.49kg, standard ISO-KF DN16 flange interface for easy integration into vacuum manifold.

Specs

Brand: PFEIFFER VACUUM Model: AVC 016 PA Product category: Electro-pneumatic bellows sealed angle valve Flange: DN16 ISO-KF Actuation: Electro-pneumatic, built-in 24V DC pilot valve Position feedback: PI reed switch indicator Leak tightness: 1×10⁻¹⁰ Pa·m³/s Compressed air supply: 4000–8000 hPa Response time: 100 ms open / 100 ms close Housing material: Aluminum Bellows: Stainless steel Seal: FKM Weight: 0.49 kg

Principle

PFEIFFER VACUUM AVC 016 PA AVC016PA receives 24V DC control signal to energize the built-in pilot solenoid valve, which switches compressed air to drive the pneumatic actuator. The actuator pushes the valve stem and bellows assembly to open or seal the valve seat. The bellows isolates vacuum gas and prevents leakage. The internal reed switch triggers when the valve reaches full open or closed position and sends status signal to control system. PFEIFFER VACUUM AVC 016 PA AVC016PA realizes reliable vacuum pipeline isolation and switching.

Applications

PFEIFFER VACUUM AVC 016 PA AVC016PA is widely used in high vacuum equipment. It is commonly applied in mass spectrometry, coating machines, vacuum furnaces, leak detectors, turbo pump stations and semiconductor small vacuum process skids. It is used for vacuum chamber isolation, roughing and high vacuum line switching, and it is a common spare part for Pfeiffer vacuum system maintenance and replacement.
