Features & Benefits
45-Degree Y-Pattern Body
Body angle of 45 degrees provides a straighter flow path than conventional T-pattern globe valves, reducing pressure drop by 40--60% and minimising turbulence and erosion.
Renewable Seat Ring
Replaceable seat ring allows in-line maintenance without removing the valve, reducing long-term ownership cost.
Stellite Disc and Seat
Stellite 6 hard-facing on both disc and seat resists erosion and galling at high velocity and high temperature, extending trim life in severe service.
Backseat Design
Stem backseat allows packing replacement while the valve is under pressure, improving maintenance safety.
Anti-Blowout Stem
Stem is retained by the bonnet geometry and cannot be ejected under pressure.
Directional Flow Marking
Body is clearly cast-marked with flow direction arrow to ensure correct installation.
