Double-controlled all-package ball valve is a switch type valve used for material transportation and interception, which can have different actuators to open and close. The ball valve is designed with compact space and double ball sealing. It is easy to install, disassemble and clean. In addition, the lower part of the ball valve is equipped with a drain hole, and each pipeline route is kept isolated during maintenance.
Double-controlled ball valve is a valve device that can control the switching state of two balls.
The working principle of the double-controlled ball valve is: when the handle is operated, the stem will drive the two spheres to rotate, so as to achieve the opening or closing of the valve. Because there are two spheres, two valves can be controlled at the same time to achieve linkage control. The double-controlled ball valve is characterized by simple connection, reliable, suitable for famous fluid media, such as gas, liquid, etc., at the same time, because of its structure, small size, light weight, so easy to install and maintain. In addition, the double-controlled ball valve also has good sealing performance and long service life.
The working principle of the double-controlled ball valve is as follows:
When the two ball valves are closed, the valve can completely cut off the medium flow and play a cutoff role.
By opening one of them, you can also open two or close any ball valve individually or simultaneously to control the flow of the medium. Because the double ball valve has two independent spheres, even if one of the spheres fails or is damaged, the other sphere can still work normally, thus improving the reliability and safety of the valve. Double control ball valve is a reliable valve device, widely used in a variety of industrial pipes and equipment, can meet different fluid control needs.
Working temperature: -30ºC+150ºC
Working pressure: 1.0MPa
Application field: For the cutting off and automatic control of abrasive and dangerous media, it is used in the occasions where stainless steel cannot effectively resist its corrosiveness, and it can replace metal valves of special materials, and has lower torque in occasions requiring large flow. It can reduce maintenance and reduce maintenance costs.
Applicable fluid: it can transport extremely strong chemically corrosive medium, withstand high temperature, vacuum resistance, and can prevent static electricity
Application areas: used in food, pharmaceutical, chemical, biological engineering and other industries
Standards Compliant: FDA and USF certification
There are various standard valve series can be supplied, they are the DIN standard series,3A standard series, SMS , ISO/IDF , BS/RJT , ASME/BPE standard etc. The constitute elements of ball valve always included: one handle, one ball body with transfixion cavity, valve body, valve central spindle and spindle shaft seal. The specification of ball valve series are welded ball valve, clamped ball valve, threaded ball valve etc.
