Walther Präzision Produktpalette

Low-temperature couplings

Quick couplings for low temperatures, for example cryogenic gas applications, temperature applications or laboratory operations.

TT-009

Features Type TT-009 - WALcryo

Type:
TT-009

Nominal bore:
9 mm

Media:
for cryogenic gas applications at temperatures to –200 °C / -328 °F (e. g. LN2), particularly for extraction of small amounts of cryogenic media.

Working pressure:
up to 10 bar / 145 psi

Materials:
plastic and stainless steel

Special features / options:
the couplings are supplied free from oil and grease and are thus suitable for all gases. They are one side self sealing, i. e. self sealing coupling with thru-type adaptor

TT-013

Features Type TT-013 - WALcryo

Type:
TT-013

Nominal bore:
13 mm

Media:
for cryogenic gas applications at temperatures to –200 °C / -328 °F (e. g. LN2), particularly for filling, transfer and removal of larger cryogenic amounts (e.g. at filling stations for mobile containers).

Working pressure:
up to 16 bar / 232 psi

Materials:
stainless steel and brass

Special features / options:
the couplings are supplied free from oil and grease and are thus suitable for all gases.  The valve technology prevents any leakage of liquid gas. Venting and shut-off valves available according to the requirements.

Features CI-T25

Type:
CI-T25

Nominal bore:
20 mm

Media:
Heat transfer fluid

Working pressures:
25 bar at 20 °C

Materials:
High-quality stainless steel 1.4404, 1.4571

Special features / options:
Use in case of tempering for the connecting of cooling modules at reaction units in lab and production plants.

A non-squirting connection and disconnection is possible through the specific design principle with clean break technology also under pressure (up to 5 bar) in a broad temperature range (-90 °C up to +230 °C).

Please urgently seek for advice in the following cases:
• Coupling/uncoupling under residual pressure
• Pulsating pressures
• Use of non-lubricating media
• Temperature-sensitive processes
• Interface reduction
• Special requirements for cleanliness
• Specific certifications
• Non-movable head of liquid
• Highly viscous media
• Optimization of flow rate
