Floating Ball Valve

详情

The series FFB Tow-Piece,floating ball valve 1/2"*6" ANSI Class ******0,1/2"*2" ANSI Class *******0,1/2"*1" ANSI Class ***0 in full and reduce port

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 barstock.

Bolted body constructions allow easy service and maintenance opration on site,Pressure rating is from class ANSI **0 up to ANSI ***0 Lbs.

Valves are usually supplied with lever operator,with gear box or bare stem on customer request.All standard floating ball valves have below features:

1. Lock device:valve is equipped iwth an integral locking device to secure line flow.
2. Blow-out proof stem:the stem is made separately from the ball with integral T-type round shoulder,which ensures total safety and integrity.
3. Anti-Static Design:grounding device are supplied form positive anti-static between ball/stem and body.
4. ISO ***1 mount plate:simplifies the installlation of actuators with standard connections.
5. Emission-firee gasket:the primary gaskey is emission free graphite to eliminate leakage.

ball valve have acquired API **7 certification,Fire safe is standard desing on all KOJO(KJV) Ball valves,

When fire burned out the primary O-ring and seat insetr,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.
