77-31200 Pneumatic soft seal butterfly valve

Overview

77-31200 Pneumatic soft seal butterfly valve is our factory in digesting and absorbing New-generation control valve products designed and developed after foreign advanced butterfly valve manufacturing technology. The series of products have reliable sealing performance, large circulation capacity, long service life and volume small, light weight, etc., can be widely used in petroleum, chemical industry, power station, metallurgy, Automated control in light industry and other industries.

Feature:

1. The 77-31200 Pneumatic soft seal butterfly valve plate adopts a double eccentric structure, which can ensure that the butterfly plate is separated at the moment of opening

The valve seat reduces the friction between the butterfly plate and the valve seat.

2. The valve seat adopts a lip-shaped flexible structure, which can compensate for changes in temperature and pressure.Now two-way sealed.

3. There are two kinds of pressure levels: ANSI Class 150 and ANSI Class 300.

In ANSI Class 150 pressure rating, 2-"~30" adopts flangeless knot Structure, 36" adopts flange single flange structure. ANSI Class 300 pressure Among the grades, 3" ~ 24" all adopt a flangeless structure. .

4. The butterfly valve sealing structure has two kinds of standard type and fire-resistant type, and the type of fire-resistant structure The fire performance meets the requirements of API 607.

5. The actuator adopts imported gear and rack double-piston pneumatic actuator. There are two types of single-acting and double-acting. The actuator has the characteristics of small size, light weight, large output torque and long life.
