Gas safety valve

A timely management of pressure spikes in an industrial plant is a part of the basic necessary safety measures. Pressure limiting valves make it easy and efficient. Safety valves, also known as pressure limiting valves, are devices which share the rupture disc's purpose of protecting an industrial plant from excessive, and thus dangerous, pressure. For this reason, besides being used separately as primary safety devices, they are often coupled together in installations. Rupture disc and safety valve may be parallel coupled to grant double protection, or the disc can be mounted downhill of the valve to protect it from the content of the piping, or the disc can be installed uphill of the valve. This latter combination is the most common, and it allows to combine the closing of the safety valve to the disc's waterproof condition, insuring better protection from damaging substances to the naturally more vulnerable valve, and thus making it last longer.
