Safe Pneumatic Connections

Product catalog summary

Overview: The document provides comprehensive details on WALTHER's WALpresta program, focusing on pneumatic connections. It covers specifications, technical data, and descriptions of components such as safety couplings, tool couplings, and spiral hoses.

Specifications:

Scratch Protection: Available in various lengths for different hose types, made from EPDM or NBR, resistant to Skydrol, and available in black.
Safety Couplings (Series LS): Designed to prevent the "whiplash effect" with a two-step unlocking system and pressure-activated control. Made from nickel-plated steel, passivated brass, and zinc-plated steel.
Tool Couplings (Series LT): Lightweight and robust, suitable for ergonomic workplaces, made from hard-coated aluminum and impact-resistant plastic.
Spiral Hoses: Made from polyurethane, available in various sizes and lengths, featuring high flow rates and resistance to abrasion and pressure.

Procedures and Recommendations:

Ensure high flow rates to avoid undersupply and efficiency loss.
Use hardened steel adaptors for safety and durability.

Technical Data:

Working pressure for couplings: up to 12 bar (174 psi).
Spiral hoses allow working pressures up to 10 bar (145 psi) at room temperature.

Configuration Examples: Examples are provided for configuring pneumatic systems using WALpresta components for optimal performance.

Accessories: Includes scratch protection and blow guns to enhance functionality and safety.

Practical Advice: Emphasizes selecting appropriately sized components to maintain system efficiency and prevent operational issues.

Key Features and Benefits:

Locking device to prevent whiplash effect during disconnection.
Easy two-step unlocking system and pressure-activated control for safe disconnection.
One-handed operation with automatic locking and high flow value at low resistance.
Cost-effective by using existing adaptors and ensuring long service life.

Product Range:

Safety Coupling Series LS: Available in sizes 6, 9, 11, 12, 23, and 38 mm.
Tool Coupling Series LT: Ergonomic and lightweight, available in sizes 6, 9, and 11 mm.
Spiral Hoses: Made of polyurethane, available in sizes 6.5 to 11 mm and lengths 4.5 to 10 m.
Accessories: Scratch protection and blow guns.

Additional Information:

Scratch protection available in EPDM and NBR versions.
Blow gun features include robust aluminum housing, low noise, and adjustable air flow.
Safety coupling series LS-C available in sizes 6, 8, and 11 mm, with automatic locking and compact design.
