Expanding gate valves

The JEV expanding gate valve consists of one gate body and related gate segment. The contact surface between are designed to mill V structure. JFM Expanding gate valves are available in sizes 2-1/16” through 4-1/16”, working pressure of 2000 psi through 5000 psi.

 

JEV Expanding gate valves Features

1.Metal seal, between gate and seat, seat and body

2.JEV Expanding gate valves design can be enforced sealing whether there is pipeline pressure.

3.Seal between full bore gate and it can be eliminate turbulence and pressure drop, makes longest service life.

4.In progress of open and close gate valve,there is space between gate and seat,this reduce torque.

5.Secondary seal of seat can prevent impurity goes into sealing surface.

6.Stem packing can used again when active by pressure.
