DESIGN FEATURES
DATIAN standard floating ball valves are manufactured in tow pieces bolted body, ball valves could be supplied full or reduced bore, designed for maximum rigidity against pipeline thrust, made from forged components or bar stock.
Bolted body constructions allow easy service and maintenance operation on-site, Pressure rating is from class ANSI 150 up to ANSI 2500 Lbs.
Valves are usually supplied with a lever operator, with gearbox or bare stem on customer request. All standard floating ball valves have below features:
Lock device: valve is equipped with an integral locking device to secure line flow.
Blow-out proof stem: the stem is made separately from the ball with an integral T-type round shoulder, which ensures total safety and integrity.
Anti-Static Design: grounding devices are supplied form positive anti-static between ball/stem and body.
ISO 5211 mount plate: simplifies the installation of actuators with standard connections.
Emission-firee gasket: the primary Gaskey is emission-free graphite to eliminate leakage.
FIRE SAFE DESIGN
DATIAN ball valve has acquired API 607 certification, Fire safe is the standard design on all DATIAN(KJV) Ball valves,
When the fire burned out the primary O-ring and seat insert, the secondary seat fire-safe packing graphite seal, and seat ring & ball metal to metal contact preloaded by spring will minimize the internal process medium leakage.
