This document provides detailed specifications and technical data for various compressed air accessories, including hoses, valves, and related components. The focus is on ball valves, shut-off and regulating valves, drain valves, manual slide valves, non-return valves, and safety valves.
Ball Valves
Ball valves are available with metal toggles and full flow, made from chromated brass. They come in various connection types: female thread, female/male thread, and male thread. The maximum operating pressure is 30 bar, with an operating temperature range from -20°C to +120°C. They are suitable for non-flammable and non-toxic gases and liquids.
Compact Ball Valves
These valves feature a metal toggle and are made from nickel-plated brass with a chromium-plated ball. They have PTFE and Viton seals and are marked according to DVGW standards. The operating pressure varies by size, with a maximum of 50 bar for smaller sizes and 25 bar for larger ones. The temperature range is -40°C to +200°C.
Shut-off and Regulating Valves
These valves are designed for manual operation with a stainless steel ball for sealing. They are suitable for non-flammable and non-toxic gases, preferably air, with a maximum operating pressure of 40 bar and a temperature range of -10°C to +90°C.
Drain Valves and Air Distributors
Drain valves are used for air exhaust and are available in straight or elbow types. They have a maximum operating pressure of 25 bar and a temperature range of 0°C to +90°C. Air distributors allow for multiple taps that can be individually shut off.
Manual Slide Valves
These 3/2-way valves are operated by axial movement and are designed for safe relieving of compressed air. They have a maximum operating pressure of 12 bar and are suitable for various pneumatic tools.
Non-return Valves
Non-return valves allow flow in one direction and are available in straight or T-form. They have a maximum operating pressure of 16 bar and are made from brass with Viton seals.
