NVD No Vent Device
Description:
The NVD No-Vent Device eliminates venting emissions from VRG Controls double-acting control instrumentation when the corresponding control valve is at full-open and full-closed positions. This is ideal for Monitor and Standby Regulators the normally remain in full-open or full-closed positions. The NVD eliminates emissions at both ends of control valve travel without adjustment. The NVD is the primary choice to eliminate emissions for all VRG Controls double-acting instrumentation. The NVD is compatible with all VRG Controls double acting control instrumentation.
