The RIEGER safety valve type SHF prevents impermissible excess pressure for vaporous and gaseous media in system components and tanks. The set pressure is generally greater than the operating pressure of the system.
The valve opens with full stroke as soon as the pressure exceeds 10 %.
The pharmaceutical, chemical and biotechnology industries as well as the cosmetics, beverage and food industries are the ideal areas of application for the RIEGER safety valve.
