HIGH-SEAL : Model GTD, FSD and MTD
GTD GTD designed for critical requirements has proven its reliability and efficiency in a wide range of application for more than 15 years. Mechanism with an eccentric structure minimizes an on-off torque at high pressure, providing tight shut-off. Carbon steel and stainless steel are standard materials for body and trim with a Teflon seat. Other special materials or particular treatment on trim and body are available as per the application and service.

FSD Having a combined function of GTD and MTD, the FSD gives a tight shut-off at nominal pressure and temperature rating. FSD sealing system consists of reinforced Teflon and metal seat structure, it requires relatively low operating torque. FSD valve works with the metal seat when a Teflon seat has been burned out. FSD provides the more reliability for steam and hot air line among its applications

BUTT WELD : Model BWD
BWD series, which has two metal seats, is primarily demanded by a distinct heating system and thermal plant where a ‘Maintenance Free’ valve is required. Since the BWD valve is welded onto the pipeline, it is made of best grade of materials and designed for a long life and a reliable performance. BWD, which is available for both butt weld and flange end connection, has a wide range of application from vacuum to high pressure and from low to high temperature. Double metal seated sealing system provides inherent fire safety characteristic and efficient flow throttle capacity.
Flange Rating : ANSI 150 and 300
Nominal Diameter : 8” to 60”
Temperature Range : Up to 650 Deg C
Features : Butt weld end, Tight shut-off at bi-flow direction, Double metal seated sealing, Light weight, compact design & easy installation.
Operating : Manual hand lever / Worm gear, Pneumatic actuator, Electric actuator.
Options : Manual operator locking device, Bonnet / Stem extension, Stellite on disc with an Inconel seat, Disc ENP coating.
