A double offset butterfly valve is a type of quarter-turn valve that has a disc with two offsets mainly used to regulate or stop media flow through the pipes. A quarter-turn valve operates in a way that when it is turned 90 degrees, the valve is either fully open or fully closed. A metal disc, also known as the butterfly, is found within the valve body that positions perpendicularly to the flow when in a fully closed position. Also known as a double eccentric butterfly valve, double offset butterfly valve is well-suited for shut-off and throttling applications dealing with viscous, corrosive, and abrasive media.
SIO high-performance butterfly valves are equipped with an advanced seat design which can be made either from EPDM or RTFE, both of which are highly-tolerant to low and high temperatures.
SIO double offset butterfly valves also feature a quick-release design that reduces the amount of torque needed to unseat the disc. They are equipped with a high strength 17-4ph stainless steel stem and graphite-reinforced or impregnated 316 stainless steel bearings that provide maximum strength for high-torque applications.
A few of the basic features that stainless steel butterfly valves manufacturers offer are
High-performance butterfly valves come with Class VI shut-off and are bubble-tight. This provides a bidirectional interference and pressure-assisted seal. This provides a maximum seal at high, medium, and low pressures.
Impregnated graphite and reinforced 316 SS bearings in the butterfly valve provide enhanced corrosion resistance. The resilient seat butterfly valve ensures long service life in severe conditions.
These pins are offset from the stem's center, putting it in compression instead of shearing. As a result, they have a greater yield point than the stems themselves.
An API 602 valve features an integrally cast disc position stop that positions the seat to achieve maximum seat and seal life.
As professional high performance butterfly valve manufacturers, benefits that we could supply include
Robust performance and incredibly easy to maintain while in operation with extended service life capabilities. For instance, a pfa lined butterfly valve offers maximum purity and reliability with minimal maintenance due to its resistance to corrosion, penetration, and microbial contaminants.
Utilizes stem seal extensions to ensure leak-proof emissions control. Use high performance butterfly valves with pressurized neck extensions to insulate pipes.
High performance butterfly valve uses reliable materials that can withstand both low and high-pressure recovery with ease. It can handle enormous flow at low-pressure differentials, like a MIV system in a hydroelectric power plant.
High performance butterfly valves can be used in various industrial applications for pressure control, flow control, and throttling.
The following standards should be present in the ball valve you are going to buy for industrial purposes-
The valve pressure range is governed by ANSI 150: 285 PSIG and ANSI 300: 740 PSIG and performs well in the temperature range of -4°F to 450°F.
