Butterfly Valve Ss 304 (D71X-16)

Butterfly valve for carrying gas

The wafer style butterfly valve is designed to maintain a seal against bi-directional pressure differential to prevent backflow in systems designed for unidirectional flow. It accomplishes this with a tightly fitting seal; I. E., gasket, o-ring, precision machined, and a flat valve face on the upstream and downstream sides of the valve.

Advantages of Butterfly Valves:

Smaller, Lighter and Economical

On-off flow control capability at quarter turn

Unaffected by precipitates

Scrach Proof: No metal to metal friction

Easy installation for all actuators: Hand Lever, pneumatic, hydraulic and electrical

Low Pressure Loss

Full Tightness prevents jamming

Easy Replacetable seat

Novel and reasonable design, special structure

Easy instllation and mintenance. It can be mounted wherever needed.

Tiny operative moment, quick 90 degrees on-off operation.

Miniminzed operating torque, energy saving.

Flow curve tending to straight line. Excellent regulation performance.

Long servie life. Standing the test of tens of thousands opening/closing operation.

Bubbles-tight sealing with no leakage under the pressure test.
