In the tank storage industry, product contamination resulting from product transfer is an obvious risk. Costs related to clean-up, product loss, waste disposal and reputational damage easily mount up to hundreds of thousands of euros. A cause of contamination is the incorrect line-up of valves between the storage tanks and the jetty, resulting in the loading... read more →

For efficient operation of boilers, frequent ‘bottom blow-down’ procedures are required to help remove sludge deposits from within the vessel. Sludge may form from dirt in the water supply or from the water treatment chemicals. Where blow-down occurs on manual valves, a safety interlock system must be implemented to ensure... read more →

An open path to relief must be maintained on Safety Relief Systems at all times during work exercises. A spare relief capacity, enables continuous production while maintenance procedures take place, and eliminates the need to isolate and shut down the whole process. Typically, twin or multiple safety relief valve systems... read more →

If sequential control is unnecessary, a valve locking device can be used to temporarily lock off the valve. The valve locking device enables individual personnel to isolate equipment while they carry out their work, safe in the knowledge that the equipment cannot be used. Sofis offers a full complement of security... read more →

Opening or closing valves in the wrong order can have disastrous consequences and cause fatal injury to operators. It can also lead to product spills, plant and equipment damage and environmental pollution. A valve interlock system is a simple mechanical device, which can be customised to implement a safe sequence of... read more →
