Double Offset Butterfly Valve

Double offset Butterfly Valve

Summary:

Flange double-eccentric soft-sealed Butterfly Valve is operated by worm gear to decelerate to drive the disc to rotate within 90°. It can be applied to cut off or regulate the flow of media. The valve can be actuated by operating lever, handle wheel, electric actuator or pneumatic actuator. Underground valve can be operated by an extended Spindle. No mater operated by electric actuator or pneumatic one, positions where the valve is opened and closed are all equipped with limit switches and indicating devices that synchronically show the opening state of the disc.

Structure:

Being double eccentric, when opened, the sealed ring of the disc is automatically off-seated after only a little degree of opening movement. The sealed ring completely bears no external pressure, which helps the valve keep longer life.

The beveled-sealed surface of the body forms a linear seal with the rubber-sealed surface, the seal ability is credible. The position of sealed ring can be adjusted in all directions to modulate the compression of the seal, which makes the valve able to be operated by minimum torque.

The disc applies the flying-disc design with a result of light weight, high rigidity, powerful strength, small flow resistance and low loss of pressure.

The stem and disc use a positioning pattern of non-penetration and pin offset to avoid shearing and abrasion of the spline caused by frequent shifting of the upper stem and to prevent abnormal opening and closing of the valve.

Technical Characteristics:

Automatic assembly and coating product line and developed process-flow ensure the outstanding ability of anti-corrosion and flawless appearances of products.

The sealed surface of base uses supersonic adhesive technology and is coated by stainless steel containing high nickel whose adhesive strength can reach to 50 Mpa.

Anti-corrosion performance

Inside and outside surfaces of the body are coated with electrostatic epoxy resin powder. The coating is even and firm with good adhesion and excellent anti-corrosion.

Sanitary standard:

Non-toxic epoxy resin powder used comply with EN sanitary standard .

The coated resin is in accordance with standards of drinking water.

Applying area:

The valve can be used in drinking water system, water supply and drainage, heat supply, gas, metallurgical industry, energy system and pipeline and so on.
