Features & Benefits
Integral Steam Jacket
Welded half-pipe jacket surrounds valve body and flanges with uniform steam distribution, preventing solidification in standby.
Full Bore Low Pressure Drop
Full-bore ball matches pipe ID for minimal flow restriction and reduced pumping energy in viscous media.
Drainable Jacket
Low-point drain connections allow complete condensate removal during shutdown, preventing water hammer and corrosion on restart.
Low Operating Torque
Mirror-polished ball and low-friction seats minimise operating torque, allowing manual operation even in large viscous-service valves.
Extended Bonnet Option
Extended bonnet with packing cooling fins available for high-temperature service above 250°C to protect actuator and operator.
