4 Inch Butterfly Valve | Durable Wafer & Lug Types, Reliable Flow Control

A 4-inch butterfly valve is a type of valve that turns a quarter turn and is often used in pipelines to control or stop the flow of fluid. A disc is attached to a shaft that rotates 90 degrees to open or close the valve. The disc is parallel to the flow while it is fully open, which lets fluid flow through nearly without restriction. While it is closed, the disk entirely blocks the flow.

People like 4-inch butterfly valves because they are small, light, and good at controlling flow. Because they are easy to operate and dependable, they are used a lot in water supply, HVAC, chemical processing, and other industrial settings.

A typical construction has a body made of ductile iron, stainless steel, or PVC, a produced disc, and a strong seat that makes it tight.

Product Features:

• Compatible with industry-standard flanges for wafer or lug-style mounting
• You can use a manual or electric actuator to turn it a quarter turn
• Pressure ratings of up to several hundred PSI are good for systems with modest pressure
• The temperature resistance depends on the materials used for the body and seat. It is usually between -40°F and 450°F
• Seals manufactured of EPDM, Viton, or PTFE to work with different types of media
• Sealing that works in both directions so that flow can go in either direction

These valves are great for isolating and throttling in pipeline systems since they are easy to use, don’t lose much pressure, and don’t need much maintenance.
