Pneumatic actuated butterfly valve manufacturers in India

Speciality Valve is a well-known Pneumatic actuated butterfly valve manufacturers in India, and they supply high-performance valves that provide accurate flow control in automated systems. The valves are lightweight, compact, and designed to meet high-demand industrial uses.

Why Required?

Pneumatic actuated butterfly valves hold particular importance in applications wherein remote actuation, rapid response time, and assured shut-off control are essentials. Since they can be added to automated processes, they are employed widely across process-based industries that value efficiency and safety.

Major Components of Pneumatic Actuated Butterfly Valve:

Valve body (cast iron, ductile iron, stainless steel)

Disc (aluminium bronze, stainless steel, or other alloys)

Stem and seat

Pneumatic actuator (double acting or spring return)

Control components such as positioners, solenoid valves, and limit switches

Working of Pneumatic Actuated Butterfly Valve:

The valve is actuated by a pneumatic actuator utilizing compressed air. The actuator turns the disc within the valve to create or block the fluid flow. The actuator is double acting (air to open and close) or spring return (air to open, spring to close), depending on application demands.

Advantages of Pneumatic Actuated Butterfly Valve:

Fast, accurate, and repeatable operation

Miniature and compact design

Simple inclusion in automated systems

Low maintenance life and low service

Optimum for throttling as well as on/off control

Applications in low as well as high pressure

Functions of Pneumatic Actuated Butterfly Valve:

On/off isolation

Flow modulation

Emergency shut-off

Remote or programmable control in process systems

Types of Pneumatic Actuated Butterfly Valve:

Wafer type pneumatic actuated butterfly valve

Lug type pneumatic actuated butterfly valve

Double flanged pneumatic butterfly valve

Double eccentric and triple eccentric types
