Duplex Butterfly Valves
Duplex 2205 Lug Butterfly Valve and UNS S31803 Instrumentation Butterfly Valves supplier in Mumbai
Valves are important devices in the piping industry as it controls and regulates the flow of media. The Duplex Butterfly Valves are designed with a quarter-turn rotatory motion that influences the flow. These valves have a compact and lightweight design having a short circular body. The duplex butterfly valve / 2205 butterfly valve has a simple construction with a disc connected to the rod. These valves have superior corrosion resistance properties and are utilized for on and off or modulating services. Duplex Stainless Steel Butterfly Valves are very precise and are very reliable. These valves get their name due to their movement shaping them into the form of a butterfly. They are very easy to maintain in difficult conditions. The Duplex 2205 Butterfly Valves require less structural support and can handle toxic and reducing media. These valves can withstand extreme heat and cold ensuring a strong sealing in the system. A Duplex Steel Wafer Type Butterfly Valve is designed with four holes that easily align to subsequent pipelines. These valves clamp easily between two or more fixtures in the piping system. The Duplex Stainless Steel Lug Butterfly Valve has threaded tapped lugs that are positioned well across bolt connections. They are well suited for an end-to-end service and have high performance in the system. CD3MN Butterfly Valve has a microstructure of both austenitic and ferritic grades.
The UNS S31803 Instrumentation Butterfly Valves help in the measurement and safety of instrument measuring services. These valves are reliable and can be operated manually or automatically. A UNS S32205 Pneumatic Butterfly Valve is designed to control and modulate the flow of air and gas. These valves have a higher nitrogen content and showcase superior corrosion resistance properties. CE3MN Flanged Butterfly Valve uses a gasket to securely seal different components efficiently.

UNS S32205 Pneumatic Butterfly Valve components
Butterfly valve body :
Butterfly valves feature bodies that fit between two pipe flanges, with lug and wafer body designs being the most prevalent.
Butterfly valve disk :
The disc is similar to a plug in a plug valve, a gate in a gate valve, or a ball in a ball valve in terms of stopping flow. In order to optimise flow, sealing, and/or operating torque, several disc designs and orientations are used.
Butterfly valve Stem :
The butterfly valve stem can be a single-piece or a two-piece (split-stem) design. Most robust seated designs insulate the stem from the media, enabling for more effective material choices in terms of cost and mechanical qualities.
Butterfly valve Seat :
To produce cutoff, the seat of a resilient-seat butterfly valve uses an interference fit between the disc edge and the seat. The seat material can be produced from a variety of elastomers or polymers. The seat can be pushed or secured into place, or it might be attached to the body.
UNS S32205 Pneumatic Butterfly Valve components
- When compared to other valves, the compact design takes significantly less space
- The weight is light
- It takes less time to open or close a quick operation
- Larger sizes are available
- Low-pressure dip followed by a return to high-pressure
Duplex Stainless Steel Lug Butterfly Valve Disadvantages
- Throttling is only available at low differential pressures.
- Cavitation and clogged flow are two possible issues.light
- Disc movement is unguided and influenced by turbulence in the flow.

Installation Procedures of Duplex Stainless Steel Butterfly Valves
- Ensure that the pipeline and flange faces are free of debris. Metal filings, pipe scale, welding slag, welding rods, and other foreign materials might restrict disc movement or harm the disc or seat.
- Because they extend to both sides of the valve, robust seated valves do not require gaskets.
- Align the pipework and spread the flanges far enough apart to allow the valve body to be fitted between them without touching the pipe flanges.
- Make sure the valve disc is adjusted to around 10% open so it doesn't become stuck in the completely seated position.
- As illustrated, place the valve between the flanges, being careful not to harm the seat faces. Always use the locating holes or a nylon sling around the neck or body to raise the valve. Never use the actuator or operator installed on the valve to lift the valve.
- Place the valve between the flanges, centre it, and tighten the bolts by hand. Carefully open the disc, making sure it does not come into contact with the insides of the pipes around.
- Close the valve disc slowly to ensure that the disc edge is clear of the neighbouring pipe flange
- Open the disc completely and tighten all flange bolts as directed.
- To guarantee adequate clearances, do a complete close to full open rotation of the disc.
