The new Ellis type GG safety interlock from Smith Flow Control is designed for use with diaphragm valves - it can be adjusted to any variations in the valve's final closed position to enable the key to be freed.
Under normal operating environments, the closed position of a diaphragm valve can vary; as most interlocks require valves to have a set closing position before the key can be released to lock the valve, this variation can have an adverse effect an interlock's operational effectiveness - it can even result in the key becoming jammed.
The Ellis GG interlock overcomes this problem by allowing the closed, key-release position to be easily adjusted to accommodate any variations in the diaphragm valve's positioning.
Used throughout the oil, gas and chemical processing industries, Smith Flow Control interlocks ensure all valve handling procedures are carried out in the correct sequence, reducing the chances of operator error.
In addition to valves, interlocks can also be used to protect switches, vessel closures, access guards, tanker loading systems and pressure and temperature sensing systems.
