Flexible metal seal butterfly valve features use and introduction

Structural features:

1 elastically sealed by torque.

2 The unique design of three-way eccentricity enables frictionless transmission between the sealing surfaces, prolonging the service life of the valve.

3 small size, light weight, light weight, easy to install.

4 Ingenious wedge design gives the valve an automatic seal function that is more tight and tight, and there are compensating and zero leaks between the sealing surfaces.

5 Replacement parts The material can be applied to various media and can be lining anti-corrosion (lining F46, GXPP, PO, etc.).

6 According to user requirements, pneumatic and electric devices can be configured to meet the needs of remote control and program control.

7 Diversified continuous structures: clips, flanges, butt welds.

Haiquangong Flexible Metal Sealing Butterfly Valve is a national key new product. The high performance elastic metal sealing butterfly valve adopts a double eccentricity and a special oblique cone elliptical seal structure. Solve the traditional eccentric butterfly valve in the open and close 0 ° ~ 10 ° instant sealing surface friction is still in the shortcomings of friction, to achieve the butterfly plate in the opening instant sealing surface is off, close the contact that is the effect of sealing, to extend the service life, the most sealing performance Good purpose.

use:

For the sulfuric acid industry gas pipeline: furnace front fan inlet and outlet, relay fan inlet and outlet, electric defogging series and connection valve, S02 main blower inlet and outlet, converter adjustment, preheater inlet and outlet adjustment and cut-off gas usage.

The sulphur-burning, conversion and dry-sucking sections used in the sulphur-burning sulphuric acid plant are the preferred brands of valves for sulphur-based sulphuric acid plants. They are considered by the majority of users as having good sealing performance, light operation, secondary corrosion, high temperature resistance, and easy operation. The flexible and reliable use of butterfly valves has been widely used.

Also widely used in chemical, petrochemical, smelting, pharmaceutical, food and other industries in SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid The medium pipe is used as a regulating and shutoff device.
