Fire Protection Wafer Type Butterfly Valve
Wafer Type Butterfly Valve
Features
1. The self-sealing center-line butterfly valve is a newly designed and innovative valve with a micro-interference between the rubber disc and valve channel, which can decrease abrasions to the sealing face, increasing the service life of valves.
2. With a self-sealing structure, the sealing property of the butterfly valve is proportional to fluid pressure, allowing the valves to withstand high pressures.
3. The sealing lip on the rubber disc can remove mud and dirt when the valve closes.
4. The outer and inner surfaces of the wafer valve are coated in a high quality epoxy powder, so the paint coat is complete and even, making the valve safe for use in the food, beverage and pharmaceutical industries.
Actuating Device
A level handle D71X, gear operator D371X, electric actuator D971X, and pneumatic actuator D671X can be installed on the valve as per customer requirements.
