Swing Arc Valve - China

FREE-VALVE brand swing arc valves are designed for ash handling system.

They use a spherical-shape dome and an inflatable-seal to ensure a 100% airtight seal.

swing arc valve is unique in its ability to open and close with a tight pressure seal in environment where abrasive material are passing.

Dome valve can achieve operating reliability in severe applications .

Features 1 - The dome is actuated through a quarter-circle arc via a rotary actuator or linear double-acting cylinder and linkage mechanism.

2 - Tight sealing performance as Inflatable seal self-compensates for wear as the valve is used.

The inflatable seal provides continuous wear compensation.

3 - The inflatable-seal is only inflated when the valve is fully closed.

This avoids shearing or jamming of particles between the seal and dome, and hence increases system reliability.

4 - Quick-exhaust valves are used to ensure rapid opening and closing of the valve.

5 - During operation, the valve provides a full-bore and unrestricted flow of material, which does not impact on the dome.

This prolong service life of the valve.

Also, the valve is “self-cleaning”.

6 - Easy to maintenance and replacement, what you should do is change the inflatable-seal.

7 - Different valve body materials are optional depending on customer need.
