Ball Valve Basics

Ball Valve

• A quarter turn (90°) valve with a spherical component, ball/sphere

• Ball controls the flow through it

• Has a hole, or port, through the middle

• Valve open - When the hole is in line with both ends of the valve, flow will occur

• Valve closed - When the hole is perpendicular to the ends of the valve, flow is

blockedblocked

Size Range

• ENIMEX S.A.

1” (DN25) – 42” (DN1100)

ANSI #150 - #600

• Enimex Ekipman

1” (DN25) – 16” (DN400)1” (DN25) – 16” (DN400)

ANSI #150-#600

Maximum Operation Pressure (MOP)

#150 = 20bar

#300 = 50bar

#600 = 100bar

Design Basics

Trunnion Mounted• Ball is fixed on a vertical axis by trunnions

• Sealing achieved by spring loaded seats

• Suitable for larger sizes and higher

pressures

Floating• Ball is free to float in the body cavity

• Sealing achieved by ball pressing on

downstream seat

• Suitable for sizes smaller sizes and lower

pressures

Reduced Bore

• Hole in the ball is smaller than

pipeline

• More economic than full bore

• Not piggable

Design Basics

Full Bore

• Oversized ball

• Hole in the ball is the same size as

pipeline

• Provides unrestricted flow

• Piggable• Piggable

• Available on all valves, floating and trunnion type

Anti- static device

• Spring loaded device inserted in stem

• Ensures electrical conductivity between body and trim

• Available on all valves, floating and trunnion type

Double Block and Bleed - DBB

• When valve is in closed position provides a seal against pressure from both ends of the valve

• Valve body cavity is able to be bled off to atmosphere

Seat Design – Floating Valves

• Simple design

• Soft sealing elements

• Material section depending on ball valve pressure rating

Pressure #150 – Pure PTFE

Pressure #300-#600 – PTFE CG (Carbon Graphite)

Seat Design – Trunnion Mounted Valves

Different seat configurations are available to cover different applications

• Primary sealing elements: Viton, PTFE Cg, Peek

• Secondary sealing: Emergency grease injection sealing

Simple Piston Effect - SPE

• Low pressure sealing is achieved by spring loaded seats

• High pressure sealing is assisted by pipeline pressure

• Seats able to provide internal cavity relief• Seats able to provide internal cavity relief

Double Piston Effect - DPE

• Seats are pressure energised in both directions

• Bi-directional sealing allows the seat to work either direction

• Seats not able to provide internal cavity relief

Seat Design

Primary Metal Secondary Soft Seats - PMSS

• Primary sealing is provided by soft sealing element

• Secondary sealing is provided by metal to metal contact

Seat with Scrapper

• Scrapper under the sealing element provides

• Excellent cleaning of ball in applications that the medium tends to adhere to the ball surfaceadhere to the ball surface

• Provides extra protection to the sealing element

Fire safe Design

• Fire resistance ability of a valve when exposed to fire

• In case of fire non fire safe materials will melt down

• Resulting to medium leakage and potential spread of fire

• Fire safe ball valves are certified according to API6FA/API607

• Design has to ensure valve integrity for 30 minutes

• Design uses metal-to-metal contact and graphite sealing as auxiliary measures• Design uses metal-to-metal contact and graphite sealing as auxiliary measures
