Pneumatic safety valves are ideal for protecting pneumatic systems and equipment from over-pressurization. If a compressor or other air source is delivering too much pressure, the safety valve opens, allowing air to escape into the environment rather than into the piece of equipment. These valves offer that extra level of safety in all kind of industrial environments—especially manufacturing plants and machine shops. Looking for more valves?
