Custom Made Clamp Butterfly Valve / Water Supply Manual Butterfly Valve

Clamp Butterfly Valve Application

Product Advantages:

1) Small in size and light in weight and maintaince.
It can be mounted whereever needed.

2) Simple, compact structure, quick 90 degree on-off operation.

3) Disc has two-way bearing, perfect seal, without leakage under
the pressure test.

4) Flow curve tending to straight-line. Excellent regulation performance.

5) Various kinds of materials, applicable to different medium.

Clamp Butterfly Valve Features:

⊙ Sealing reliable

Body and disc made of ductile iron which promote the impact resistance and pressure-bearing

capacity, sealing ring made of rubber and valve seat’s sealing surface is conical shaped, make the

sealing capacity more reliable.

⊙ Excellent corrosion protection

Inside electrostatic epoxy resin power coating or vitreous enamel(upon request), outside electrostatic

epoxy resin power coating.

1. BRIEF INTRODUCTION:

The butterfly valve is operated by the disc rotating form 0° to 90°, can be applied to cut off or regulate

the flow of medium.

The valve can be actuated by operating lever, handle wheel electric actuator or pneumatic actuator.

Widely used for potable water supply, waste water treatment, electric power plant, gas supply,

warm-air system, smelting plant, ship building, textile, petroleum, chemistry, or other light industries.
