Product Description
Metal seated butterfly valve is the newly-developed long-life and energy-saving products.
A metal seated butterfly valve is a type of valve which can be used for isolating or regulating flow. The closing mechanism is the disc, which sits in the center of the valve body. The disc is connected to a handle or actuator via the shaft, which passes from the disc through the top of the valve body. Unlike a ball valve, the disc of the butterfly valve is always present in the flow, which will induce a pressure drop.
• Triple offset geometry
• Integral metal seal ring sealing
• Zero Leakage for both way
• Anti-blow out shaft
• Fire safe design to API607
• Replaceable Seat & Disc Sealing
• 0°-90°control, no jump area
• Friction free
A metal seated butterfly valve operates in a quarter turn style, meaning that rotating the closed disc 90° will fully open the valve, and vice versa. They can also be opened incrementally in order to throttle flow.
A metal seated butterfly valve operates in a quarter turn style, meaning that rotating the closed disc 90° will fully open the valve, and vice versa. They can also be opened incrementally in order to throttle flow. This can be accomplished manually, but throttling flow is more precise when used in conjunction with an actuator. Actuators can be customized to allow incremental flow, by using positioners in the case of pneumatic and hydraulic actuators, or by using modulating boards in the case of electric actuators.
Applications of Metal Seat Butterfly Valves
Metal Seated Butterfly Valve is widely used in petroleum, natural gas, piped gas and medicine, food industry, industrial environmental water treatment and shipping industry.
