The small-bore valve family
Controtek forged steel gate, globe and check (NRV) valves have a compact design for high pressure and are manufactured to API 602 for pipelines up to 50NB. Ends are threaded or socket weld. Hard-faced trim gives perfect sealing and longer life, and seating surfaces are precisely machined and lapped.
Forged gate valves
Full-port isolation for drains, vents and instrument roots. Supplied across India for refinery, power and process piping.
Forged globe valves
Throttling and regulating on small-bore high-pressure lines.
Forged check valves
Piston-type NRVs without springs for low pressure drop.
