Features

◆ Positive Bi-directional Shut-Off:Full rating bi-directional pressure energized sealing system.Helicoflex metal seat and spring energized teflon seat provide positive shut-off.For rubber or flat metal seat type positive shut-off is generated by line pressure.

◆ Economic Alternatives to gate,ball and plug valves.

◆ Corrosion free:Stems and body are not in contact with line media.Bodies are protected with epoxy coating.

◆ Self centering disc by axial movement due to the floating coupling.

◆ Compact light weight wafer design.

◆ Anti blow out stem.

The upper stem is fully retained by the retainer plate under pressure in unlikely event of primary seal fail.

◆ Easy replaceable seat without any special tools.

◆ Easy installation for each type of actuators:manual,pneumatic,hydraulic and electric.

◆ Wide range of material for various conditions.

◆ Simple maintenance-seat and stem packing retrofit without removing actuator.

◆ Minimal flow loss and turbulance.

◆ Reliable for flow control.

◆Wide temperature range ： -100 ℃ ～＋ 400 ℃.

◆Valve size 40mm ～ 1200 mm , also special as requied.
