Series 66 Power Activated Valve

• The Basic Control Valve 66 Globe and 66 Angle is a full port engineered valve. Equipped with two diaphragm chambers, sealed from each other by the diaphragm, and isolated from the valve’s main flow passage by an intermediate plate. By pressurizing one control chamber while simultaneously venting the other, the valve is positively powered to both open and close.
• A large majority of OCV control valves have a single diaphragm chamber and operate off line pressure; more specifically, off the pressure differential between the inlet and outlet ports of the valve. There are, however, conditions that do not lend themselves to such an operation. For example, adequate differential to properly actuate the valve may not exist, the liquid being handled may be extremely dirty or otherwise unsuitable, or design of the system may, for some reason, make it preferable to use an outside power source. Under such conditions, the OCV Power Actuated Valve 66/66A provides an excellent solution.

Model 66 Power Actuated Valve

The Model 66 provides an excellent solution for applications where there is inadequate differential pressure to actuate properly, the fluid being handled is extremely dirty or otherwise unsuitable, or it is preferable to use an outside fluid pressure source.  Typical examples include tank safety (petroleum applications), pump control, low line pressure on/off, and solenoid valves.
