The RIEGER Safety valve Type SH prevents excessive pressure in steam and gaseous media in plant components and tanks. The set pressure is generally higher than the operating pressure of the system.
Already at 10% overpressure valve opens with full stroke.
The pharmaceutical and chemical industries as well as the biotechnology, like the cosmetics, food and beverage industry, are the ideal applications for the RIEGER safety valve.
