Years Service Life
360° Replaceable Rubber Seat
Full-circle rubber seat securely fixed with a retainer ring, ensuring continuous sealing contact across the entire circumference.
Two-Piece SS630 Shaft Design
Stub shaft design reduces friction and ensures smooth operation with improved mechanical strength for reliable actuator integration.
Low Head Loss Disc Design
Optimized disc profile delivers a higher flow coefficient (Cv), reducing pressure drop and improving overall flow efficiency across the system.
Maintenance-Free Bearing System
Aluminium bronze bushings provide high strength and wear resistance with no lubrication required, delivering long-term stable operation.
Reliable Shaft Sealing System
Multiple O-rings combined with V-type packing ensure tight sealing around the shaft area, with online adjustment capability for minimal downtime.
Replaceable & Adjustable Packing
Extended top bracket allows easy access to packing. Adjust or replace without removing actuator, reducing maintenance complexity in the field.
Flexible Disc Structure (Solid / Lattice)
Available in solid disc or lattice disc for large sizes. Lattice design reduces weight and operating torque while maintaining structural integrity.
