Working pressures

When a gate valve remains open for long periods of time and the body’s internal walls are parallel, a very large torque is required to close it. The inside of the D model body has a conical shape which provides more space; moreover, the width between the faces in this type of valves is greater than standard, thus achieving more space. This way, when the valve is shut off the solids stored inside it can be easily released.
