Rising Stem Ball Valve
Design Features / 1
3Z Rising stem ball valve(RSV) has mechanism to enable dualaction and gets sealing by the acting of tilting & turn. Generally,it has low torque prominently compared to other ball valves.So, the size of actuator is to be small and our customer canadjust it if there is some leakage in using.
3Z Rising stem ball valve is perfect in sealing. It is easy to exchange seat because of top entry type,based on the field situation, and it has long life cycle as there is no friction and abrasion.

How the 3Z Rising Stem Ball Valve WorksDesign Features
2 / Design Features How the 3Z Rising Stem Ball Valve Works / 3
The core and seat ring contacts directly and seated as metal-to-metal.To prevent the surfaces from galling or abrading, the valve is designed to operate in the following steps :
3Z developed a unique special mechanism. The 3Z mechanism provides low torque and smooth,frictionless operation. This mechanism is provided as a standard in 3Z rising stem ball Valves.
1. Close positionPerfect sealing in core and seat by the working of cam mechanism after stem’s falling.
Low Torque
Low operation torque by enabling the dual action with special mechanism.
Non-Slam
Not occurring the situation of slam as special mechanism induces stem to do linear action.
No Thermal Expansion
No thermal expansion situation as there is no closed space with thesingle seating design.
Optimum Flow
Enabling full bore orreduced bore productsand having high Cv numerical value.
Corrosion & Erosion
Resistance Material
Strong corrosion and erosion to be applied on the seating part of core.
Perfect Friction Free
Reducing the seat abrasionby being rotated after core is separated from seat completely.
Self Cleaning
During core is openor close, self cleaning is performed for seat.
Energized Sealing
Perfect sealingmechanically, not using spring or other assistive devices.
Inline Maintenance
Easy seat exchange and lineinspection/cleaning withthe top entry type.
Special Mechanism
Operating after dividedTilting and Turn action clearly.
Indicator
This indicatesthe direction of the plug.
2. TiltingAs stem is rising, core becomes tilting and then core gets separated from seat.
3. RotatingCore is turned by rotating of stem in order to be perfect open position of port.
4. Open positionCore becomes open completely after stem has rotated.

FeatureThere is no diminished flow with the full bore port, and also easy to pigging. For applicationsuch as high viscosity condensable media, high efficiency is demonstrated with full bore port.
3Z rising stem full bore valves are designed to meet the requirement to minimize pressure drop inchemical plant, such as hydrocarbons, ammonia, ethylene etc... within high or low temperature range.
