What is Resilient Seated Butterfly valve?

SIO’s Resilient Seated Butterfly Valves are made for effective regulation and isolation of media.  Resilient seated butterfly valve is a type of butterfly valve that has a rubber (or resilient) seat between the external diameter of the disc and the internal wall of the valve.

SIO will ensure that all resilient seat butterfly valves when customised according to industrial needs will be maintenance-free and cost-effective. SIO ensures silicon-free production for a reliable operational value. They are lightweight and often used for high-pressure conditions.

Resilient Seated Butterfly Valve

Resilient Seated Butterfly Valve Features

Often the design of a resilient seated butterfly valve comes with a one piece disc/stem design. This is highly advantageous in any environment for hygiene maintenance and promoting durability.

SIO’s stem materials ensure compatibility with the type of resilient seated butterfly valve you are buying: stainless steel or BUNA-N/EDM Molded over Stainless Steel.

With durable construction and long service life, SIO’s resilient seated butterfly valves can be used in Sanitary Service with Mildly Corrosive and Toxic Media.

SIO ensures that all of their resilient seated butterfly valves come with an Integral ISO 5211 Actuator Mounting Flange for easy actuation

Why use Resilient Seated Butterfly Valve

Cost-effective

With a resilient seated butterfly valve from SIO, you can get effective solutions that are highly cost efficient especially when compared to other types of valves. The wafer type butterfly valve is the most affordable option you will get in butterfly valves.

Less Maintenance

SIO’s butterfly valves are made with careful consideration into maintenance free function with a longer life. Butterfly valves have reduced operating costs and longer life without rearing maintenance.

Emission Free Stem Sealing Service

For added protection and complete isolation, and effective media entrapment, two types of seals (primary and secondary) are applied during production. Based on the type of seal, you can choose a teflon lined butterfly valve.

Standard and specification of Resilient Seated Butterfly Valve

Perfect Precision

With SIO’s high precision equipment, one standard you cannot afford to miss is the specification related to leakage and time sensitive performance. The SIO valves are relatively best when it comes to accuracy and ensures premium quality results.

Valve Capacity

The specifications in manufacturing resilient seated butterfly valves is related to the amount of fluid passing through the pipeline in a given time period. The valve capacity differs from one model to another model. Sometimes, it changes based on the valve types as well.

Control Options

Controlling the flow of fluid in a system is extremely important for easy regulation. While controlling the fluid, the seats made of FKM, EPDM, PTFE Lined EPDM, BUNA-N, and Polyurethane need to be chosen so that they do not chemically react with the media.

Common Metal Seated Ball Valve Applications

Chemical Industries

Chemical industries include different types of materials and media that can be toxic to handle at close proximity. Resilient seated butterfly Valves are perfect for their non-reaction to different types of chemicals. The main of manufacturing is stainless steel, preventing corrosion and abrasion.

Food and Beverage Industries

Food and beverage industries see great use of resilient seated butterfly valves. These valves are designed to tolerate Cleaning and Sterilization in Place (CIP and SIP) acids. The design helps in hygienic production, crucial in food production.

Oil and Gas Industries

Oil and gas industries require adequate handling of high temperature and pressure conditions. Resilient seated butterfly valves also prevent leakage and deterioration from corrosive fluids.

Water and Wastewater Services

Because resilient seated butterfly valves have extreme resistance to different types of media, they work well in water treatment plants. The one-piece body construction adds to their durability and prevents both external and internal leakage. Fluids like solvents, slurry and sludge can be tolerated by these valves.

Resilient Seated Butterfly valve Factory

With a butterfly valve, you want the manufacturing to be done with high-precision equipment. The valves have to be connected to an external system which makes it essential for the manufacturing to be precise to prevent any leakage. 

Butterfly valves are compact in size and we clean them through ultrasonic cleaning facilities. . SIO specializes in manufacturing and debug inspection of resilient and high performance butterfly valve, we could supply bulks of the valve without any compromise of quality.

Different Types of Resilient Seated Butterfly Valves Options

Epoxy-Coated Ductile Iron Body

TThe valve body of our concentric butterfly valve is made from ductile iron that guarantees durability, reliability, and long service life. It features more mechanical strength than cast iron so there are minimum chances of breakage.

Integral ISO 5211 Actuator Mounting Flange

Electric and pneumatic valve actuators of our resilient seated butterfly valves are provided with ISO 5211 valve mounting flanges, which are directly mounted for actuation of butterfly valves in system operations.

Emission-free Stem Sealing Device

SIO’s concentric butterfly valve is made with a rubber O-ring that effectively prevents external leakage. The O-ring maintains a tight contact between the spherical design of the rubber seat and the top and bottom ends of the disc. With its positive sealing, all operations are guaranteed emission-free.

Seat Materials

As a leading industrial valve manufacturer in China, we provide seats of our resilient seated in two durable materials:

Manual Operators

Automatic Actuators

Resilient Seated Butterfly Valve by Bonnet / Body Connection

Wafer Type End Butterfly Valve
Lug Type End Butterfly Valve

Wafer Type End Butterfly Valve

The wafer-type end connection helps with tight sealing to prevent internal and external leakage. They stop backflow, especially in relation to the bidirectional flow of the media. SIO’s wafer type butterfly valves are easy to install and maintain.

Lug Type End Butterfly Valve

SIO manufactures a lug type butterfly valve for ease of use during system maintenance. Lug type ends are efficient in maintenance and replacement of different parts of the pipeline.
