FLOATING BALL VALVES - DESIGN
LCM Floating Ball Valves can be supplied full or reduced bore, designed for maximum rigidity
against pipeline thrust, made from hot forged components or barstock.
Bolted and screwed body constructions allow easy service and maintenance
operation on site.
End connections are SW or NPT for series HD and EB, FF-RF-RTJ-BW for SB
series.
Pressure rating is from class ANSI 150 up to ANSI 2500 Lbs.
Valves are usually supplied with lever operator, with gear box or bare stem on
customer request.

MATERIALS SELECTION
Valves are designed to guarantee a perfect seal by means of suitable materials of
seat also for high pressure applications.
For hight temperature application, seats and ball are supplied with metal to
metal contact by means of tungsten carbide overlay.
STEM
Stem is made separately from the ball, anti blow-up design with suitable PTFE
ring, OR in viton, graphite rings and antistatic device. On request stem can be
also supplied with extension for special applications or insulation.
BALL
Solid type is usually made in Stainless Steel, Carbon Steel ENP, Special Alloy
and with tungsten carbide overly for metal to metal service.
TESTS
All valves are tested in accordance with BS 6755 part. 1, API 6D, API 598,
MSS-SP-61 and ASME B 16.104.
EXTERNAL COATING
Carbon Steel valves are usually protected with phosfatinzing for series HD and
WN, zinc plated (th. 7-12 µ) for series SB, EB, EE.
Valves can be also supplied unpainted or with special coats finishing according
to customer request.
ACCESSORIES
Drain plug, locking devices, transition pieces (pipe ends), extended bonnet for
underground installation, gearbox, electric, pneumatic or hydraulic actuators
where foreseen by our standard design.
