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 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
Common Metal Seated Ball Valve Applications
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:
- BUNA-N: This material is used for resistance to a number of different media. One can find it applied in chemical and food industries.
- EPDM: Ethylene-propylene Diene Monomer or EPDM is resistant to wear and tear over continuous use in chemical and pharmaceuticals.
Manual Operators
- Manual Lever Handle: Used for easy on/off of media flow.The operator can easily handle the flow through quick turning of the handle.
- Manual Geared Hand Wheel: Helps in precise regulation without compromising isolation. This type of manual operator goes a step further than the handle by giving better control.
Automatic Actuators
- Electric Actuators: Cost-effective options for automation actuation. Electric actuators will require vontant electrical connection to function properly.
- Pneumatic Actuators (Spring Return and Double-acting): They are safe for use across multiple industries due to their non-flammable properties.
Resilient Seated Butterfly Valve by Bonnet / Body Connection
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.
