3/2-way valve »Blue Series«, R 1/8 o., R 1/8 o., thread coating - Riegler 110104

3/2-way valve »Blue Series«, R 1/8 o., R 1/8 o., with thread coating, pmin 1.5 bar, pmax temp. 15 bar, Plastic / NPB Push-in fittings series manufactured in plastic and nickel-plated brass. All parts are suitable for use with hoses, tubes or pipes made of plastic. In contrast to the simple shut-off valve, this valve not only controls the flow of a medium, but also enables venting when closing - by turning the knob (3/2-way).

About Function connectors

Function fittings add a second job to the line itself, such as throttling exhaust air or blocking one direction, which saves a separate valve and its piping. They install like an ordinary push-in fitting and run on compressed air up to 10 bar. The group holds 335 articles for tube outside diameters from 3 to 12 mm.

What matters when choosing

• The thread sets the mounting point. Parallel G threads from G 1/8 to G 1/2, tapered R threads in the same sizes and M3 or M5 for small ports are available.
• The tube O.D. from 3 to 12 mm has to match the existing line. On throttle versions it also decides, together with the thread, which body shapes exist.
• Working pressure tops out at 10 bar. Some versions reach down to -0.95 bar and therefore suit vacuum sections, while others require a minimum of 1.5 bar.
• The series fixes the body size. Blue Series is the standard build, Blue Series mini covers tight installation spaces.
• Versions with two threads are defined by thread 1 and thread 2, for example a step from G 1/2 to G 1/4. Decide first which side is screwed in permanently.

Typical applications

• Setting extend and retract speed of pneumatic cylinders right at the cylinder port
• Blocking one flow direction so stored air cannot run back on a pressure drop
• Isolating a single consumer for maintenance without draining the main line
• Balancing cycle times of grippers and slides on a handling station
• Merging two supply lines in a distribution run inside the control cabinet

All parts are made from plastic and nickel-plated brass and sealed with NBR, threads follow DIN EN ISO 228-1, ISO 7-1 and DIN 13-1. The specified medium is compressed air.
