3Z Double Block & Bleed (DBB)
Valve: Designed to meet Oil & gas transmission, loading, unloading needs. Line sealing is achieved by body and wedges cut from each side of the plug with or without the assistance of soft seat rings. The sealing is positively made on each side of the plug (double block), and the media kept in the plug port area can be bled into upstream or to the container to prevent explosion. The Valve can be used for assuring metering accuracy and SCADA systems.

3Z Teflon sleeved Plug Valves
Designed for chemical, petrochemical, pulp & power, mining, power generation industries and such. Line sealing is achieved by soft sleeve seat located in between metal body and plug using engineering plastics, such as PTFE, PFA, UHMPE or high temperature plastics. Steam sealing is achieved by 3-fold seating system. Body and plug materials are supplied in various high alloy materials.

3Z Teflon Lined Plug Valves & Lined Piping Accessories
Designed for excessively corrosive materials handling economically avoiding use of expensive exotic metals. Designed for the same processes for the 3Z sleeved plug valves. The whole wet area is lined with melt-processible PFA, or FEP materials backed by carbon steel or ductile iron in body and plug. Lined materials are universally thick and held tight in the locking cavities to prevent from warping and changing in its dimensions.

3Z Metal Seated plug Valves, Non-Lubricated
Designed to cope with higher temperature applications of the 3Z sleeved and lined products. Line sealing is achieved by metal to metal contact between body and plug. To avoid damage on the sealing surfaces, during opening and closing, the plug is lifted first, and rotated 90 degrees, and then, set to its desired position. The whole opening and closing operation is achieved by one action assuring full proof operation using specially designed and patented operating mechanism by 3Z.

3Z Metal Seated Plug Valves, Lubricated
Line sealing is achieved basically by metal to metal contact between body and plug with assistance of sealant injected in between body and plug, which serves both sealing and lubricating during Designed for Crude oil, Oil, Natural gas handling and transmission operation.
Uniqueness of dynamically and pressure balanced design together with inverted plug design, assure prevention of locking, which has been the problems of conventional design at higher pressure application.

 |
3Z Eccentric plug Valves
Designed to meet higher CV requirements and excessive sludge handling in such as sewage treatment plant or waste water treatment plant. Line seal is achieved by and eccentric plug and metal body. The plug is designed in half shape of concentric plug, and centered eccentrically to seat smooth on the seat sealing surface in pressing motion.
The plugs can be supplied with or without elastomer coated.
