// How It Works
Engineered for reliable pneumatic transfer.
The purpose of the RULA Dome Valve is to isolate the product flow in Pressure Vessel filling and discharge for dry free flowing non-sticking bulk materials. The Dome Valve’s unique design allows the dome to cut through material during opening and closing. The dome is driven by a pneumatic actuator. An inflatable seal ensures a perfect closure. These functions are controlled by a control box with a programmable PLC.
Types of Actuation
- Pneumatic actuated
Design Features
- Programmable PLC will give an alarm when the seal does not inflate to its pressure setpoint
- PLC will give an alarm when valve does not reach its open or close position
- The inflatable Seal is protected and out of the material flow stream
- Relatively simple and very robust design with minimal movable parts
- When open the dome moves out of the material flow opening the entire cross section of the valve for material flow
- Chrome-plate dome
