1,Small size, light weight, excellent cutting performance
2. Sealing surface of the disc relative disc designed for a skewed
axis of cone surface, making the disc sealing surface of valve seat
sealing surface with a certain contact angle, the contact angle
evenly around its circumference is equal to a thin wedge-shaped
face, and the circumference of the disc vertical Seal for
elliptical curve line was s sure, both played a role in sealing the
compensation.
3. Disc sealing surface in the off state, even by force, pressure
capacity high; butterfly plate in the opening process, the sealing
surface of each point from the seat sealing surface at the same
time to complete the action, not crowded card phenomenon, almost no
friction, open the moment minimal. Therefore, low cost, good
sealing performance and long life.
4, Sealing structure for a variety of options, life assurance and
reliability. Butterfly ring with integral soft seal (PTFE, C-TFE,
G-TFE), hardening of metal-piece, monolithic + carbide for various
conditions
5 To achieve two-way sealing function, which can be adjusted, but
also has cut off function.
6 Executive body of low friction, high efficiency, thrust a large,
good security.
7 The implementing agencies smart model, combined type (manual
agencies) is designed to ensure that the direction of free
installation and flexible control.
8, Simple eye-catching and reliable integration of travel
directions and limit switch and solenoid valve combination of
installation, no external piping, to reduce leakage point.
9 Implementing agencies for various forms of selection to meet
different user requirements
10 Assembly and easy maintenance, with excellent cost performance
