Main Design Features

Konstruksi Bodi: One-piece die forged body, dense structure, high strength, eliminates casting defects, suitable for high temperature and high pressure services
Bonnet Connection: Bolted bonnet design with 304/flexible graphite spiral wound gasket sealing
Disc Design: Renewable disc type, hardfaced seating surface for durability
Stem Design: Backseat feature allows packing replacement under pressure when valve is fully open
Operating Characteristics: Disc moves linearly along seat centerline, short stroke, reliable shut-off
Flow Direction: Flow below seat design, reducing operating torque and protecting packing
Packing: Flexible graphite packing, low emission design
Kursi: Renewable seat rings or integral hardfacing
