Detail Information
The dome valve seal automatically deflates during opening and closing, thereby avoiding contact with the medium.
The silicon rubber seal automatically inflates only when dome and eliminating unnecessary wear the dome is in fully closed position.
2.Dome valve was operated by two independent solenoid valves, one control valve open and close, the other control seat air inflation and exhaust. This design can make zero abrasion between seat ring and spherical surface.
3.Low maintenance and quickly replacement.
4.Mainly materials casting steel stainless steel, and cast iron. Teflon, tungsten carbide, chrome carbide or other coatings available according to customer's requirements.
2.End Connection: ASME or customer's requirement
3.Face to face: ASME B16.10
4. Inspection and Testing: API 598
Design Features:
1. Different Pneumatic Actuator Types are for customer's choice, such as "Fanshaped model", "AT Model" or "Swing Model"
2. Air-in makes rubber seat inflat to contact ball when valve is in full close position.Air-fail makes rubber seat shrink to uncontact ball while valve is open. This design will make no friction between ball and seat when sealing is optional.
3. Different ball surface heat treatments are to suit different application, such as "Chroming,Tungsten Carbide"
4. Valve body can be extended in any length to meet end user's special requirements.
5. Rubber seat material EPDM, Viton, Silicon Rubber all are available.
