Pneumatic Safety Valves - Grainger Industrial Supply
网页Pneumatic safety valves control air pressure in compressed air/pneumatic systems. These pressure-relief valves allow excess pressure to escape by opening when a threshold pressure is reached, preventing damage to equipment or possible injury to workers.
Vacuum & Pressure Relief Valves - Grainger Industrial Supply
网页Vacuum and pressure relief valves connect to compatible pneumatic systems and prevent pressure imbalances from damaging the system or causing catastrophic failures such as overpressure or high vacuum conditions.
What is a Pressure Relief Valve? | IMI Norgren
网页2019年3月25日 · A pressure relief valve (PRV) is a type of safety-related component used in the pipeline or with vessels in pneumatics. Relief valves are used to limit the amount of compressed air pressure in a system so that it doesn’t build up above a pre-set level and cause damage to machinery or people.
Pressure Relief Valves - How They Work | Tameson.com
网页2021年1月19日 · Pressure relief valves are essential to keeping hydraulic and pneumatic systems below the set pressure. Depending on the installation, they can either: Reduce the downstream pressure to a constant level whenever it exceeds a threshold. Maintain sustained pressures down- or upstream from the valve.
