Severn Glocon (UK) has developed a solution for positive valve stem gland security, enabling changes in performance to be safely monitored during the service life of the valve. Using the latest gland stem sealing technologies, the Severn Glocon system differs from other designs by providing progressive early warning of any change in the performance of the patented live-loaded double stem packing, offering increased operational and safety benefits in comparison with conventional bellow seals. The design is based on a multi-function manifold block, which, in normal operation, enables any valve stem gland leakage to be safely routed to a flare or secure storage system. Routine gland leakage monitoring is easily performed by repositioning the two ball valves on the manifold, which enables the pressure of any leakage to be indicated on the integral gauge. A measure of the leak rate can be observed by the
increase in indicated pressure over a set period of time, enabling any remedial maintenance to be accurately predicted and planned. The Severn Glocon fugitive emissions monitoring system is suitable for linear and rotary motion valves of virtually any size. The patented design is CE marked and in conformance with the latest Pressure Equipment and ATEX Directives.
