• When sampling, a sample is drawn from the process and taken into a sample container.
• For liquids, this container consists of a bottle with a threaded, open-top cap.
• Between the bottle and cap a self-sealing diaphragm (septum) is placed.
• The septum is of such material that when pulled from the needles, it reseals.

• A Dopak single coil, tube/shell type sample cooler is an effective and efficient heat exchanger.
• The compact design of this sample cooler makes it easy to install, next to a Dopak sampling system mounted on a stainless steel support plate.
• The sample cooler protects the sampling system against high temperatures and ensures safe sampling.
• It protects the sampling system against high temperatures and ensures safe sampling.

• The Dopak double coil, bucket type sample cooler is an effective and efficient heat exchanger where higher flow is required.
• Standard tube side material is SS316/316(L).
• Other material is available on request.

The sample bottle adapter (SBA) for Dopak liquid samplers offers zero emission during the filling
 of the bottle.
The SBA ensures an advanced way of sampling without the need to use a needle assembly and a bottle with cap and septum.
Dopak Sample Bottle Adapter is also available with the extra safety feature No Bottle No Flow (NBNF).

The SBA for Dopak liquid samplers improves safety in the widest sense:

• Local spillage can be avoided
• Volatile substances should not escape into the atmosphere during filling of the bottle
• Vent gases can be vented through a special vent connection

Dopak has developed a spring return handle to serve the markets growing demand for more safety and ergonomics. A spring return handle ensures a normally closed position of the 2-way valve when valve is not being operated. 

Features: 

• Normally closed position of valve when not being operated
• Handle torque is adjustable with specific range
• Handle has an adjustable damper to provide controlled closing of the valve and to prevent damage on the stem seals
• Position of handle can be change 180°
• Designed for ISO 5211 topworks 

Specifications: 

• Material : Stainless steel for externals. Plastic handle cover.
• ISO 5211 topwork : F03, F04, F05 and F07.
• Stem extensions : 40 mm (standard), 80 or 120 mm.
• Torque : 15, 25 or 35 Nm.

In order to generate the correct code for the Dopak Spring Return Handle, suited for pipe spec ball valves with ISO 5211 Topworks, please measure the items of A, B and C in mm: 

• A Stem width
• B Stem actuating height
• C Total height 

and select one of the options of D, E and F:

• D ISO 5211 Topworks type: F03, F04, F05 or F07
• E Torque: 15, 25 or 35 Nm
• F Stem Extension: 40 (standard), 80 or 120 mm
