butterfly valve with worm gear
Product Details
The valve can be used in drinking water system, water supply and drainage, heat supply, gas, metallurgical industry, energy system and pineline and so on.
Applying area:
.
The coated resin is in accordance with standards of drinking water.
Non-toxic epoxy resin powder used comply with sanitary standard GB/T 17219-1998.
Sanitary standard:
.
The coating is even and firm with good adhesion and excellent anti-corrosion.
Indide and outside surfaces of the body are coated with electrostatic epoxy resin powder.
Anti-corrosion performance:
.
The sealed surface of the base uses supersonic adhesive technology and is coated by stainless steel containing high nickel whose adhesive strength can reach to 50Mpa.
Automatic assembly and coating product line and developed process-flow ensure the outstanding ability of anti-corrosion and flawless appearances of products.
Technical characteristics:
.
The stem and disc use a positioning pattern of non-penetration and pinoffset 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.
.
The disc applies the flying-disc design with a result of light weight, high rigidity, powerful strength, small flowresistance and low loss of pressure.
The bevelled- sealed surface of the body forms a linear seal with the rubber-sealed surface, the sealability 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 minimun torque.
.
Being double essentric, 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.
Structure:
.
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 matter 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.
.
Flange double-essentric soft-sealed butterfly valve is operated by worm gear to decelerate to drive the disc to rotate within 90
