KSB SICCA Gate Valves — Overview
KSB manufactures three series of SICCA gate valves covering the full range of industrial isolation requirements — from standard bolted bonnet designs for general service, to high-pressure pressure seal valves for power plant main steam lines, to compact forged steel valves for small-bore high-pressure piping.
As an authorized KSB dealer serving Pune, Ahmednagar and Beed, Johar Engineering supplies all three SICCA gate valve series with genuine KSB factory warranty, complete technical documentation, and valve servicing support.
Product Range — Three SICCA Series
SICCA 150-600 GTC
Standard cast steel gate valve with bolted bonnet for general industrial service. Features flexible wedge design for reliable sealing under thermal cycling, OS&Y rising stem, hard-faced seat/disc interface (13% chrome steel or Stellite), and fully confined bonnet gasket. Compliant with Indian Boiler Regulations 1950.
SICCA 900-3600 GTC
High-pressure cast steel gate valve with pressure seal bonnet design. As internal pressure increases, the bonnet seal becomes progressively tighter. Features split wedge with internal pressure balancing, Stellite 6 hard-faced seats, non-rotating rising stem, and butt weld ends. Available in Standard Class and Special Class versions. IBR compliant.
SICCA 800-2500 GTF
Compact forged steel gate valve for small-bore, high-pressure piping. Class 800 features bolted bonnet; Class 1500 and 2500 use welded bonnet for added safety. Solid wedge design, non-rotating stem, burnished stem shank for extended packing life. Available with socket weld, threaded, or butt weld ends.
