SAFE SYSTEMS Helping create a safer place to work It is of vital importance that any industrial automation process is considered to provide a safe working environment for its operators and those around it. Compressed air is an extremely versatile and safe medium but if used incorrectly can also provide a major hazard to personal safety. Ever present from the early days of machine automation, IMI Precision Engineering has been able to offer solutions that assist our customers in achieving this safe workplace using many standard product ranges. In addition, we have over 50 years of experience of...

SAFE SYSTEMS Electrically operated safety valves No additional electronic monitoring SCVA cross monitored safety valve In situations requiring a complex machine system to be rendered safe during an emergency, then a dual cross monitored dump valve is essential. The SCVA is a pneumatically monitored valve eliminating the need for further electronic systems in order to meet the requirements of DIN EN ISO13849-1 "e Cat.4" or similar. Downstream air is exhausted in the shortest possible time due to the very high reverse flow (up to 30,000 l/min). > Four port sizes in both BSP and NPT thread forms...

SAFE SYSTEMS Electrically monitored Olympian Plus 64 Series Monitored soft start dump valves This range of products, whilst not including the cross monitoring function, does have the facility to provide an electrical output indicating the valve status. This can be incorporated into the machine control system where required – for example in a 2 channel system requiring a level of redundancy. Available in both Excelon and Olympian Plus ranges. MB series high performance silencers/mufflers > Rate of pressure build up can be adjusted to suit the application > High capacity dump facility for optimum...

SAFE SYSTEMS Manually operated safety valves Lockout Hasp for multiple padlocks Inline lockout valves When carrying out maintenance duties on machine installations, of vital importance is the safety of the personnel engaged in the work. “LOTO” or “lock out tag out” is a primary function before any work begins. The air supply to the area should be isolated and the downstream air exhausted quickly and safely then locked to ensure safety of the workforce. Our lock out valves provide a solution to this task, and are easily fitted into the system. > Valves can only be locked in the “off” position...

SAFE SYSTEMS Lockable ball valves Simple isolation of specific sections of a compressed air ring main can assist in safety and benefit energy efficiency. Machines left unattended with the supply connected could potentially offer a hazard if unauthorised use occurs. In addition, any air leakage overnight or during shutdown periods increases energy cost. The IMI Norgren lockable ball valve presents a simple, fast solution to the problem. Lockable in the “off” position by means of a simple padlock with downstream air exhausted via a threaded port. Port Size Full Bore Lockable Ball Valve Full Bore...

SAFE SYSTEMS Pressure control and accessory products Pressure relief valves Pressure relief valves are often ignored when designing and installing compressed air systems, but are vital to ensure maximum cost effectiveness and safety. Best practice dictates that every pneumatic system should include a means of protection against over-pressurisation. IMI Precision Engineering has a wide and varied selection of relief valves for all manner of applications, from simple “pop type” devices to more complex larger capacity units. > Prevents the build up of excess pressure which could lead to machine...

SAFE SYSTEMS anti-flay protection Air fuses Throughout industrial automation, extensive use is made of flexible hoses used to connect together two or more portable devices. Should this hose fail in service either via damage or excessive wear, then escaping air can create a major hazard to personal safety. A simple air fuse, correctly installed, can provide an effective anti-flay device should failure occur. Following repair of the hose, the airfuse resets automatically for subsequent use. > Tamper-proof - requires no adjustment > Number of options of size and flow capacity > Minimal pressure...

SAFE SYSTEMS Actuator control devices passive lock Piston rod locks When a pneumatic actuator is exhausted, the piston rod is free to move. This unregulated movement could present a major hazard to safety during an emergency condition on a machine application. Imagine a vertically mounted actuator carrying a heavy machine slide or similar – the actuator will simply drop under the effect of gravity. A piston rod lock, fitted to the actuator during manufacture, is a mechanical locking device holding the piston rod secure during this kind of situation. The lock is “passive” – therefore when an air...

SAFE SYSTEMS Olympian Plus mounting two inlets Exhaust control devices MQ00 series Coalescing exhaust silencers Whilst most modern pneumatic products will operate successfully with non lubricated air, in most cases lubrication is still used to prolong the life of products in a system. Exhausting air can however present major hazards for machine operators and others creating harmful noise levels and air borne pollutants. A large capacity coalescing silencer can be utilised to capture this air, reclassifying the oil into liquid form for safe collection and reducing noise to an acceptable level....
