The OCV Truck/Rail Car Loading Valve Model 115-3 controls fuel flow into tanker trucks or railroad cars. This model has dual solenoid operation and multiple opening and closing stages. The heavy-duty, nylon reinforced diaphragm coupled with the rectangular-shaped, soft seat seal that creates a drip-tight Class VI closure, ensure high quality performance from this OCV valve for the long term. The 115-3 is easily maintained without removal from the line and stamped with a serial number for convenient customer service and part replacement.
