Pfeiffer IV 16 M, Vacuum Automated Safety Valve Package for Turbo Pump and HiScroll, 24 VDC, DN 25, PD Z10 050 / PDZ10050
Pfeiffer IV 16 M Key Features:
- 24 VDC Input Voltages
- Valve is normally closed
- Direct installation on the vacuum flange HiScroll, control via accessory port
- This does not have ATEX certification
IV 16 M / PDZ10050 Overview:
The vacuum safety valve is a normally closed, direct-acting 2/2-way solenoid valve. When de-energized, the valve remains shut. In systems where vacuum pumps discharge directly to the atmosphere, the valve isolates the vacuum chamber from the supply line, preventing unintended pressure increases. In turbopump applications, it is installed in the fore-vacuum line to safeguard both the process vacuum and the turbopump from accidental venting or backflow, particularly after the backing pump is turned off or during a power outage.
IV 16 M Scope of Delivery:
- Valve body with valve coil
- Fastening pack with components for installation
- 1x preconfigured cable with AccessLink and cable socket
- Operating instructions
IV 16 M Applications:
- Feature to protect against inadvertent venting of a turbopump after backing pump has been turned off.
- Feature to protect against inadvertent venting after vacuum pump has been turned off.
