Flowserve Ball Sector Valve

* Flowserve Ball Sector Valve: Primary characteristics NAF-Trimsector Z-trim has a new approach for solving the problem of cavitation and high noise level. The design is based on our well-established NAF-Setball ball sector valve. The NAF Setball with Z-trim combines the benefits of an advanced control valve with the simplicity of a ball sector valve. The valve has · A ball sector with trim splits the flow into many other flow paths and the pressure drop in 3 steps. This unique design offer substantial control benefits. · A ball sector with top and bottom bearings, trunion design, require very low operating torques, this enables the use of lower torque actuators. · A V-shaped sector that provides accurate control over a wide operating range, even at low flow rates. · The NAF-standard for actuator mounting utilizes a ” direct mounting method.” This method results in superior control and a compact valve/ actuator assembly.
