Secure operational pressure with IL220 lock-up valve

As an industry rule and to ensure efficiencies, downtime on all pro- duction lines should be kept a complete minimum. Brian Abbott, Product Manager at SMC Pneumatics elaborates, saying: “SMC supports our customers in this regard by constantly developing products that help contribute towards avoiding downtime, as well as ensuring the critical safe integrity of a system.” Adding to its offering is SMC’s IL220 lock-up valve of the IL200 series. “This valve helps to maintain the operational pressure, even when supply pressure is lost by switching to a second supply of pressure as a 3/2 way valve”. The maintenance of the operational pressure and/or switching to a second pressure supply ensures the shift position of the valve further down the production line. “The advantage here is that the system retains a defined valve position should this fault occur,” says Abbott. The IL220 lock-up valve has many talents. It is suitable for use in all industrial applications where the operational pressure has to be ensured even in the case of a loss of the main pressure supply. Highly sensitive instrumentation for process control would benefit where a safe or last position needs to be maintained either via a secondary supply line or a back-up tank. Here the IL220 does the switch automatically when the set critical pressure is reached. As it is completely mechanical even a loss in electrical system monitor- ing does not affect the safe switching of the valve. Enquiries: Email sales@smcpneumatics.co.za
