Series LS large nominal sizes

Quick couplings for compressed air safety with pressure controlled unlocking devices prevent an early release of the coupling. Only after reduction of the working pressure to below approx. 1,5 bar the fitting can be disconnected mechanically. This technical version does not allow any operating error, i. e. the dangerous „whip effect“ is avoided.

LS GN
3D Serie-LS GN

Features Series LS large nominal sizes

Types:
LS-012, LS-023, LS-038

Nominal bores:
12, 23 and 38 mm

Working pressure:
up to 16 bar

Media:
compressed air

Materials:
coupling housing: nickel-plated brass, crank disc: nickel-plated brass

Special Features / Options:
compressed air safety coupling for high flow rates
(free pass when valve is opened)
Unlocking only possible with low residual pressure (this avoids the dangerous whip effect completely)

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
