High Performance butterfly valve


  • Class VI shut-off, Bubble tight
  • Advanced Seat Design:
  • Provides a bi-directional interference and pressure assisted seal.
  • This provides maximum seal at high, medium and low pressures
  • Extended Neck
  • Allows for up to two inches of pipe insulation
  • Positive Seal Packing Design
  • PTFE is a cup and cone system and Graphite is die formed rings
  • Graphite Impregnated or Reinforced 316 SS Bearings
  • Ensure long service life
  • High Strength 17-4 ph SS Stem
  • Provides maximum strength for high-torque applications
  • Quick-Release Disc Design
  • Reduces amount of torque needed to un-seat disc.
  • Disc Taper Pins
  • Pins are offset from the center of the stem which places them in compression rather than in sheer. This gives them a yield point greater than the stem itself.
  • Integrally Cast Disc Position Stop
  • Machined position stop on the body locates the disc in the seat to achieve maximum seat and seal life.

High Performance Butterfly Valve Manufacturer

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.

Features of High Performance Butterfly Valve

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.

Disc Taper Pins

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.

Robust Design

An API 602 valve features an integrally cast disc position stop that positions the seat to achieve maximum seat and seal life.

Benefits from High Performance Butterfly Valve manufacturers

As professional high performance butterfly valve manufacturers, benefits that we could supply include


Efficient performance

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.

Wide service range

High performance butterfly valves can be used in various industrial applications for pressure control, flow control, and throttling.

Standard and specification of High Performance Butterfly Valve

The following standards should be present in the ball valve you are going to buy for industrial purposes-

  • High-performance butterfly valve’s body is made of Carbon Steel or Stainless Steel, Disc from Stainless Steel and Seats with EPDM, RPTFE ensuring quality. Our teflon lined butterfly valves, for instance, use Teflon for a better surface.
  • They are available in sizes up to 60 inches (1.52 m), making them suitable for use in larger applications. Both wafer and lugged end connections are available in 2″ to 12″
  • High performance butterfly valves feature actuators like Electric, Pneumatic (spring return), and Pneumatic (double acting)

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. 

Standard-Based High Performance Butterfly Valve For Your Unique Service

Power Generation Plants

Power plants use steam and water through pipes for industrial applications and use many valves to control their flow. Applications like these involve corrosive and abrasive media, as well as varying pressures and temperatures. SIO butterfly valves are made from stainless steel or carbon steel To survive such demanding conditions.

Hydrocarbon Processing

We manufacture a high performance butterfly valve with adjustable stem packing that ensures a tight seal and reduces emissions significantly. Stainless steel is used for the valve's stem, which is durable enough to support high pressure. Major applications of butterfly valves for gas services can be observed in hydrocarbon processing. Industries use a metal seat butterfly valve in oil refineries and LNG operations.

Pulp and Paper Industries

Paper and pulp industries use a variety of industrial chemicals that are considered hazardous, corrosive, and abrasive. Double offset butterfly valves use bi-directional interference to ensure a tight seal and eliminate leakage risks. Stainless steel or carbon steel body and RTFE seats make it ideal for pulp and paper industries

Chemical and Petrochemical Industries

Chemical and petrochemical industries commonly handle hazardous, corrosive, and abrasive media such as petroleum, ethylene, and propylene. High performance butterfly valve has valve seats made from EPDM to withstand chemicals, solvents, oils, and fatty acids. In addition to the stainless steel body, the valve is also durable to handle severe conditions, such as high pressures, low pressures, cryogenic temperatures, and media that are toxic.

Water and Wastewater Treatment

Application areas for water and wastewater treatment include dealing with various fluid flows, including waste, slurries, and water. With pressure ratings up to 285 PSI for the #150 and up to 740 PSI for the #300 and temperatures between -4°F and 450°F, butterfly valves with a double offset are well suited to handle these requirements.
