Pressure Rating PN-10
Nominal Diameter 1.5" - 5"
The RAF-P OG is an hydraulic valve operated by line pressure. The valve is a 3-W on/off control valve that can be commanded from a remote location, by an hydraulic control relay - (Hydraulic relay)
The OG can be configured to perform as a Normally Open (N.O.) or as a Normally Closed (N.C.) valve. The valve is fully open when the control chamber is disconnected from line pressure and vented into the atmosphere.
The 3-W Hydraulic relay configuration together with Raphael's patented diaphragm enables smooth and precise downstream pressure control.
* in situations where the opening and closing control unit is installed in a central location and connected with the field valves by control tubing.
* in locations with lightening hazard that damages electric control valves with unprotected solenoid installations.
