Description
The ISB Valves continuously internally monitor themselves with each operation. In the event that the valve detects a malfunction, the valve will self-lock and will only reset itself when power is removed and the normal operation is restored. An auxiliary external pressure monitoring system with manual reset is available as an option. Two optional pressure switches are required for this option.
The ½", ¾" and 1" Valves are available in stock for immediate delivery. Dual Safety Valves are supplied standard with 120VAC Solenoids and connectors with built-in varistors. Optional 24VDC Solenoids can be provided upon request.
MEP-A is a series of safety valves designed with an intrinsically dynamic safety control system. MEP-A's are redundant (double-body), parallel flow pneumatically actuated valves, rated to limit in case of malfunction the residual pressure to values under 3% of the inlet pressure. Their inherent dynamic monitoring system blocks valve operation safety in case an inner leakage occurs, also if very low and not detectable by usual position sensors.
