Manual butterfly valve and introduces the characteristics of 1, small portable, easy disassembling and maintenance, and can be installed in any position.
2, the structure is simple, compact, 90 & deg;
Rotary opening and closing fast.
3, operating torque, energy saving and lighter.
4, flow curve tending to straight line. Excellent regulation performance.
5, opening and closing test times as many as tens of thousands of times, long service life.
6, to achieve completely sealed, gas leak test is zero.
7, manual butterfly valve has simple structure, light weight, material consumption, installation size is small, low driving torque, etc, used for truncation, connected, regulate medium in pipe has good flow control characteristics and close the sealing performance.
8, manual butterfly valve can transport the mud, and the apertures least accumulated liquid.
Under low pressure, can achieve good sealing.
Adjust the good performance.
9, the butterfly plate streamline design, make the loss of the fluid resistance is small, is a kind of energy-saving products.
10, manual butterfly valve stem for stem structure, through conditioning processing, has the good comprehensive mechanical properties and corrosion resistance, abrasion resistance.
When manual butterfly valve opening and closing the valve stem make rotation movement up and down and run, not only the valve stem packing is not easy to damage, reliable sealing.
With the butterfly plate fixed cone pin, overhanging end to prevent rushed out of the design, in order to avoid in the stem and disc joint stem collapse accident broke out.
Driving type is manual, worm gear drive, electric, pneumatic, hydraulic, electric hydraulic linkage, etc. , which can realize far control and automation.
