Dry Gas Couplings are used to prevent ex-cess spillage. They protect people and pro-

perty from dangerous and costly exposureby keeping hazardous liquids and vaporsin-line and out of the environment.

Dry Gas Couplings are used at liquid or va-por transfer points where you do not wantproduct loss. Using Dry Gas couplings willreduce the hazards typically found whenhandling/processing LPG

DGCouplings®

Dry Gas Couplings

The Dry Gas Coupling is deveoped for

connection and disconnection at higher

pressure (1"-4" up to 25 bar).

ATEX approved

II 2G

• Spillfree handling for loading and unlo-ading tank trucks, rail tankers and tankcontainers.

• Minimization spillage and product losskeeps the environment free from Hazar-dous Vapors and Liquids.

• “Easy to Use” – design saves time andminimises health risks.

• Reliability and easy servicing saves yourinvestment.

• Approved for safe handling of LPG- Propane (CAS 74-98-6, UN 1978) and

Dust Cap

Dust Cap for increased safety

It´s only possible to remove the cap from the Tank unit /Adap-ter after pulling the securing stift and at the same time twistingthe cap. The Dust Cap is manually lockable with padlock.

Standard Caps in Composite (Polyeten PE-HD 300).

It covers the widest range of chemical and petroleum products.

Use the Mann Tek Dust Plug to prevent ingressof dirt and water in the couplings.

The material in the Dust Plug is Composite,Aluminium and Stainless Steel.

Pressure Cap - Working Pressure PN 25 bar / 363 psi

The Mann Tek Pressure Cap for Tank units / Adapters is designed to maxi-

mize operator safety and containment safety.

Features

• Pressure indicator • Depressurization• Customs / tamper seal feature• Automatic locking• Manually lockable (with padlock)

3rd closure (valve) on Rail tankers, Containers and Tank trucksThe pressure caps are allowed by ADR/RID regulations as 3rd closure on Rail tankers,

Containers and Tank trucks. Meaning that the Pressure Cap can be used instead of thetraditional Ball Valves.

A Dust Cap gives very good protection against corrosion, and

withstands both hot and cold environments.

Tank units with no parts protruding from the coupling

Used when Tank unit is installed direct to a Ball Valve or

similar situation where space is limited so the Tank unitspindle can not project backwards.

Pressure relief valve for DGC Hose and Tank unit is used toprevent "over pressure" in systems cause by terminal expan-tion or as safety "pressure control" valve.

When the pressure reaches a certain level the valve opensand releases the over pressure.

This system

dissipates trapped

uid pressure

into hose coupler

without spillage, to

allow easy con-

nection.

Features

Swivel Joints are used in the indus-

try wherever a movable pipe-connection

system between two equipment parts is

needed.

The swivel joints are designed for slow

rotary motions under the inuence of high

internal pressures and/or big external stress

such as traction and bending forces.

With an appropriate combination of swivel joints nearly all movements from the simple

rotation or swivelling motion up to motional

actions in space can be realized.

SBCouplings®

Safety Break-away Couplings

Safety Break-away couplings are used to

prevent pull away accidents, the internal

valves will close the ow in both lines

and prevent unwanted release of pro-

duct.

The Safety Break-away couplings are

available as Industrial and Marine type.

Industrial Break-aways are used at x

points like manifolds, pipelines depots etc. The Safety Break-away couplings are usedin lling systems for airelds, rail tank cars,

tank containers etc.

Sizes 1" (DN25) to 12" (DN 300)

Working pressure Max 25 Bar (363 psi)

Materials Aluminium, Brass, Stainless steel, Hastelloy,Titanium. Others on request.

Connections

Female and Male BSP / NPT, ACME,Witworth threads and anged DIN and

ANSI. Others on request.

Industrial Break-away coupling isutilized all industrial product trans-fer installations.

The industrial SBCouplings are specically

designed to be able to activate with a tensileforce being applied at an angle to the planeof the coupling housing, up to 90 degrees.

Features

• Passive security against situationswhere a hose or loading arm could besubjected to inadvertent excessive loads.

• Design features are a simple mechanismand no loose components which could be

lost after release.

• Operates independently of shut off safetysystem and does not require an externalpower source.

• Easy to reset on site with one person

• High owrate / low pressure drop

• Very low loss, positive shut-off of bothcoupling halves results in minimum

product loss.

• Lightweight and robust design.

• Available with ANSI/DIN anges orthreaded (BSP or NPT).

Industrial Break-awayTypically installed into loading arm and hoseassemblies, where at least one side of the

coupling is attached to a rig and xed point.

Release with a tensile force being

applied at an angle to the plane

of the coupling housing,

up to 90 degrees.

How it works- before and emergency

disconnect

When the SBCouplings separate, it allows the

valves to close. The two valves closes rapidly,minimizing exposure to personnel and theenvironment.

The safety break-away valve consists of twohalves, each with a valve that has a o-ring seal.

The SBCouplings, Safety break-away

couplings has three external breakbolts. In the case of axial tension all of

the bolts take up the force correspond-

ing to the break force on the hose with

a safety margin.

Non-axial forces concentrate the ten-

sion forces more strongly on one bolt,

so that the safety break-away coupling

reacts in a natural way to the reduc-tion of the hose break forces.
