SLIDING TYPE

One operator turns hand wheel and unique gear-set mechanism makes a gap without pipe spreading. By Sliding Blind plate manually, Open/Close Blind position is changed. All blinding process completes within 3 minutes safely and easily. Sturdy and simple design shall make high reliability with the most advanced technology and durability.

SWING TYPE

It take within 3 minutes for one operator to blank a line, operating the handwheel and rotating the blind into place without line spreading. Again, all inline movement is internal, eliminating the potential for pipe-joint stress. As one of the most popular model, quick operation with no line spread and correct spectacle positioner shall make easy and safe pipe line isolation.

COMPACT TYPE

The Compact type is designed for replacement of existing valves, limited F-F dimension or large diameter pipeline applications or limited space for installation. It is designed with a short face to face, and has tapped bolt holes for easy installation between flanges. The compact design also reduces weight and requirement for extra pipe support.

NON-SPILL TYPE

Non spill type of Line Blind has good advantages in Oil terminal & offshore applications where is limited installation space and marine pollution is strictly prohibited. The 3 sides covered body & compact design prevents ground pollution and it allows to install at parallel pipe lines.

JACK BOLT TYPE

The traditional style of line blind offers a broad range of pressures and a lower cost. The basic standard for line blinding for many years. After turning 3~7 jack bolts around the body to make a gap by round bar or wrench and then change the blind plate position. Pipe line needs to be spreaded for operation.

Extreme Line Blind

EX Type blind valve offers 100% isolation for severe service with extreme temperature and pressure
/or cryogenic (-196℃) application.Sample picture shows an application at 1500F(816℃) 2500 LBS, DN 500
No internal gasket with simple structure minimize contact surface with extreme media and unique spreading mechanism
make a gap to switch blind plate position in a short time.Strong torque for tightness with solid structure enable to isolate severe pipeline with safe.
Only gasket replacement of blind plate is needed for maintenance.
