Valve

Actuator controller comprising a body () with an inlet port () coupled to a source of pressurized fluid and in flow communication with primary and secondary spool bores (); primary and secondary spools (); first and second cross flow ports () communicating said primary and secondary spool bores, compression and expansion outlet ports () for applying pressurized fluid to a return-biased actuator (); and a venting outlet port (); wherein return action of the working piston of the actuator is facilitated with aid of pressurized fluid already gained in the system.

Actuator controller

The invention relates to a network system for monitoring valves in a facility, which comprises: (a) a plurality of valve monitoring devices&#x2014;VMDs, each monitoring device is affixed to a valve, and comprises: (a.1) a sensor for sensing the status of the valve; (a.2) short range wireless communication unit for transmitting the status as sensed by said sensor, and for transmitting the status as sensed, together with an identification of said device, to one or more Valve Device Readers&#x2014;VDRs located within said short range; (a.3) mechanism for affixing the device to the monitored valve in a manner which does not disturb the normal operation of the valve; and (a.4) one or more VDRs for receiving the transmission of the valve status and VMD identification from said VMDs, and for forwarding the same to a server by Ethernet communication.
