Butterfly Valves
C&R believes that butterfly valves are the valves of the future because of following advantages that it has over other valves:
- Light-weight design resulting in lower cost and ease of handling
- Smaller face to face dimensions making it an economic choice especially for line sizes above 8" compared to other bulkier options like gate valves.
- Due to relatively high coefficient of flow (Cv) and relatively low pressure drop the pump size is minimized and system wear reduced compared to other low recovery valves like globe valves.
C & R's range of butterfly valves includes centre mounted hand lever and gear operated valves in both the lug and flanged end type. C & R also manufactures off centre mounted valves of the wafer, lug and flanged end type.

A Pneumatic Butterfly Valve is a type of quarter-turn valve in which the disc (butterfly) controls the flow of fluid, and it is operated by a pneumatic actuator using compressed air. This makes it faster and easier to automate compared to manually operated butterfly valves.
🔹 Key Components:-
Valve Body – usually wafer, lug, or double flanged type.
-
Disc (Butterfly) – rotates 90° to open or close the flow.
-
Seat/Lining – soft-seated (EPDM, NBR, PTFE) or metal-seated, ensures sealing.
-
Shaft/Stem – connects disc to actuator.
-
Pneumatic Actuator – double acting or spring return (single acting).
Gear Operated Butterfly Valve
| Minimum Order Quantity | 1 Piece |
| Size | 300 mm |
| Valve Size | More than 24 inch |
| Body Material | Ductile Iron |
| End Connection | Wafer |
A Gear Operated Butterfly Valve is a quarter-turn butterfly valve operated through a gearbox mechanism instead of a simple hand lever. The gearbox uses a handwheel connected to gears, which reduces the torque required to rotate the disc, making it easier to operate—especially in large-diameter valves or higher-pressure applications.
