Pneumatic Butterfly Valves Manufacturer & Supplier in India - Concorde Valves & Automations
Pneumatic butterfly valves deliver fast, efficient flow control with low pressure loss. Concorde Valves & Automations is India’s leading manufacturer and supplier of pneumatic actuated butterfly valves, including butterfly valves with pneumatic actuators for automated plants. Below you’ll find types, working, applications, and benefits so you can choose the right pneumatic butterfly valve for your process.
What are Pneumatic Butterfly Valves?
Pneumatic butterfly valves are quarter-turn valves that use a rotating disc to start, stop, or throttle flow. A pneumatic actuator powered by compressed air turns the disc for quick, repeatable operation. Suitable for water treatment, oil & gas, and chemical processing, they handle a wide range of clean liquids, gases, and utilities with simple integration and low maintenance.
Types of Pneumatic Butterfly Valves
Pneumatic Wafer Butterfly Valve
The pneumatic wafer butterfly valve fits between two flanges. It’s lightweight and economical, ideal where space is limited. The wafer design helps maintain a tight seal and resists backflow.
Lug Type Pneumatic Operated Butterfly Valve
The lug type pneumatic operated butterfly valve uses threaded lugs for bolting to each flange. It allows downstream maintenance without disturbing upstream piping, making isolation simple and safe.
Flanged Butterfly Valve with Pneumatic Actuator
The flanged butterfly valve with pneumatic actuator is built for higher pressures and robust connections. Flanged ends provide strong, secure mounting and excellent alignment in heavy-duty service.
How Does a Butterfly Valve with Pneumatic Actuator Work?
A pneumatic actuated butterfly valve converts compressed air into rotary motion to position the disc. Options include double-acting (air to open and close) or single-acting/spring return (air in one direction, spring to fail to a safe position). Selection depends on your required fail-safe state and control philosophy.
Benefits of Pneumatic Actuator Operated Butterfly Valves
