The Victaulic Series 761 Vic-300 MasterSeal butterfly valve assembly combines a grooved butterfly valve with a VSI double-acting pneumatic actuator. Available in 3-inch and 4-inch sizes, it provides air-operated flow control for compatible water-truck plumbing and industrial piping systems.
A double-acting actuator uses control air to move the valve in both directions. Confirm the available air supply, control components, and required failure behavior before selecting this assembly.

| Application | Typical Function |
|---|---|
| Water truck plumbing | Air-operated main-line water control |

| Item to Confirm | Why It Matters |
|---|---|
| Control-air pressure | Must meet the installed actuator’s operating requirements |
| Seat material | Must be compatible with the fluid and temperature |
| Failure position | Double-acting actuators do not provide inherent spring-return action |
| Solenoid and controls | Accessories must match the vehicle or control system |
| Available clearance | Actuator increases the assembly’s overall dimensions |
Selection note: Confirm the installed actuator model, control-air requirements, seat material, fluid compatibility, and control accessories before ordering. Follow current Victaulic and VSI installation instructions.
