DETAIL DESCRIPTION

Wafer Butterfly Valve

Brief Introduction

The butterfly valve is operated by the disc rotating form 0° to 90°, can be applied to cut off or regulate the flow of medium. The valve can be actuator by operating lever, handle wheel electric actuator or pneumatic actuator. Widely used for potable water supply and distribution, waste water treatment, electric power plant, gas supply, warm-air system, smelting plant, ship building, textile, petroleum, chemistry, or other light industries.
