WITT is a manufacturer of safety relief valves or pressure relief valves. Safety relief valves respectively pressure relief valves or pressure safety valves are designed to protect against overpressure by discharging pressurised gases (e.g. acetylene, ammonia, argon, CO2, helium, carbon monoxide, methane, propane, oxygen, nitrogen, hydrogen and compressed air) and vapours from pipelines, pressure vessels and plant components. Safety relief valves are often the last line of defence against explosion – and such an explosion could be fatal. Other common names for safety relief valves are pressure relief valve, safety valve, or blow-off valve.
There are two distinct ranges of Safety Relief Valve from Witt: 500mbar to 45 Bar; and a highly developed and unique range from 5 up to 500 mbar. Protect your sensitive systems and pipelines with the best from Witt!
WITT safety relief valves are available in brass or stainless steel, as ventable version, and with or without condensation outlet.
