Product Details
Features
- The disc will freely close as a result of reversed flow.
- Complete disc closure at no flow conditions is assured by an off-set between the seating surface and the lever.
- The disc is provided with an anti-rotational device to avoid damage due to induced flow instability.
- Free swinging disc operation when the actuator is in open position (pressurized cylinder and compressed spring).
- A vertical seat design, a large opening angle of the disc (75°) and an accurate design of the�internal geometry gives a very limited internal turbulence. This results in reduced pressure loss.
- During the fast air exhaust the compressed spring allows a closure in less than 1 sec (the complete seat closure will be effective only when the steam flow becomes zero).
- The actuator action is limited to the first part of the stroke leaving a free swinging motion of the disc for few degrees when it is near the closed position. This avoids possible deformation by repeated internal shocks by forced closure.
- The standard actuator configuration includes: limit switches, pressure gauge and filter, quick exhaust valve and local closure test device.
- Quarter turn actuators assures the safety conditions for operators.
