EB Series Ball Valves

EB Series One-Piece Instrumentation Ball Valves are part of the growing family of FloLok instrumentation valves. They are designed for analytical sampling and conditioning systems, control systems, and other medium-pressure applications. EB Series ball valves use one-piece encapsulating packing to ensure leak-tight operation and provide positive shutoff in high- low- and dynamic pressure applications. The encapsulating PTFE packing eliminates dead space to reduce purging time and improve system cleanliness. EB Series ball valves also feature an innovative packing retainer that prevents the stem from blowing out when making inline packing adjustments.

Features

Ball Valve Options and Ordering Information

Tube Fitting End Connections

SSP can provide three tube fitting designs for all FloLok valves without changing the end-to-end dimensions of the valve. Use the designators below to indicate the required design.

Design	Description	Designator
Duolok	2-Ferrule	D
Unilok	1-Ferrule	U
Griplok	2-Ferrule	G

Body Material

Select the valve body material from the table below then add the designator to the basic part number.

Example: 43GAD4-316

Material	Designator
316 Stainless Steel	-316
Brass	-B

Vented Ball Valves

2-Way Vented Valves

The downstream port vents to atmosphere through a vent hole in the side of the valve body when the valve is closed.

Angle Pattern and 3-Way Vented Valves

The bottom port vents to atmosphere through a vent hole in the side of the valve body when the valve is closed. The pressure rating for vented valves is 500 psig (34.4 bar).

Ordering Vented Ball Valves

To order vented valves, add V after the flow pattern designator.

Example: 42GXVD4-316

Important Cross-Vent Flow Warning

To prevent cross-vent flow, order a vented valve with a smaller vent orifice. Add the designator from the table below to the part number.

Example: 42GXVD4-316-040

Valve Size	Orifice in.(mm)	Designator
41, 42	0.040 (1.02)	-040
43, 44, 45	0.049 (1.24)	-049
45	0.093 (2.36)	-093

Special Cleaning

EB Series ball valves are available with oxygen compatible lubricant and with no lubrication. To specify special cleaning, add the designator from the table below to the part number. Note: Valves with no lubrication have a pressure rating of 500 psig (34.4 bar). Valves with oxygen compatible lubrication are rated to -30°F.

Example: 43GAD4-316-RD-XP98

Description	Designator
Oxygen compatible cleaning	-XP98
No Lube	-XP97

Special Flow Paths

EB Series ball valves are available with special flow paths to accommodate sampling, draining, purging, tee flow and other applications. See the EB Ball Valves Catalog for additional information.

Handle Options

Stainless steel reinforced black nylon handles are standard on EB Series ball valves. To select a handle color, add the designator from the table below to the basic part number.

Example: 43GAD4-316-RD

Handle Color	Designator
Black	None
Green	-GR
Red	-RD
Blue	-BL
Yellow	-YW
Orange	-OG
No Handle	-NH

Locking Devices

Locking devices for EB Series ball valves are available for both 2-way and 3-way ball valves. Compact locking devices are available for 2-way 42, 43 and 45 Series valves. To order standard locking devices add -LD to the part number. For compact devices add -LD2 to the part number. Example: 43GD6-316-LD. To order locking device kits for installation, see the EB Series ball valves catalog.
