M&S safety valves
M&S safety valves are TÜV-certified fittings that are used to protect hygienic pressure-bearing systems, such as pressure vessels or piping systems, in the event of an impermissible pressure increase. When the preset maximum operating pressure is reached, the valve opens, thereby reducing the system pressure. Once the excess pressure has been reduced, the valve closes and the system can continue to operate safely.
M&S safety valves comply with the requirements of the Pressure Equipment Directive (PED 2014/68/EU) as safety devices for pressure limitation or pressure relief in production facilities.
