--The design of top-guided flow, in comparison with the cage control valve, reduces the friction and disturbance of the media to avoid the failure of the mechanical guidance caused by the accumulation of the unpurified media to ensure the stable performance as well as to decrease the noise and the friction.
--Easy to change parts inside the control valve. The single-seat construction with a balanced plug allows massive flow of the unpurified media with a high differential pressure that requires less output of the actuator.
--Control Valve Series Z offers a choice of different materials to meet the working conditions. The partly or complete build-up welding of the seat and the body with Stellite Alloy ensures the capability of corrosion resistance and abrasion resistance.
--The self alignment requires no gasket between stem and plug, plug and seat or body and seat.
--The complete seal of the body and seat ensured by the screwed connection does not destroy the self-alignment as no gasket is required and as a result, requires less maintenance. The Tapper-junction of stem and plug avoids the concentration of the work on the pin, which may break the connection of stem and plug.
--To ensure the seal of up to Grade VI, the screw connection of the body and seat offers a choice of different metallic and non-metallic materials.
--To ensure the least leakage of the media, Control Valve Series S offers choices of packing seal up to Grade III.
--Better controlling ability with design of "Flow-to-open".
--Also available with choice of design of built-in low-noise cage and or with design of cavitation resistance.
