Pneumatic Actuated Ball Valve Trunnion Type Soft/Metal Seat Ball
Valve ASME CLASS 150/300/600/900/1500/2500
This Series are Trunnion-mounted ball valves designed with vanguard
engineering and highly sophisticated technology. Our in-house High
Velocity Oxygen Fuel-sprayed hard faces allow them to defy the
toughest operating conditions, such as high pressure, abrasive and
corrosive mediums, slurries, etc. Successfully used in the Oil &
Gas industry, Refineries and Power Plants, these API 6D
certificated valves provide an outstanding tightness, stability,
safety and reliability that exceed most industry standards.

PRODUCT FEATURES
True bidirectional design and wide temperature range satisfying all
applications.
Cavity pressure relief design protecting against any excess of
pressure in the body cavity.
Trunnion ball design ensuring a tight contact between seats and
balls, and allowing the valves to withstand extremely high
pressures.
Single Piston seat rings that guarantees the self-relief of the
body cavity in case of overpressure.
Double piston design in option, securing both upstream and
downstream sealings.
Optional double block and bleed design ensuring a safe isolation
simultaneously on both upstream and downstream seats.
Splined stem design strengthening the trim to withstand heavy
torques under high pressure drops.
Emergency sealant injection design on request to restore the seat
or packing integrity immediately.
Optional drain plug device to empty the cavity or to detect any
leakage.
Body gland providing a trustworthy anti-blowout function and an
easy maintenance.
Several alternatives of soft and metal seats to meet any kinds of
requirement.
Optional purge device guaranteeing a complete cleaning of the body
cavity.
Fire safe design according to API 607 or API 6FA.
Anti-static device.
ISO 5211 Mounting Pad design.
