Product Overview

On a G1/2 air line, back-flow can drain a receiver or allow a downstream circuit to bleed back. The ASCO 34602126 is a metal-body Series 346 non-return valve that allows pneumatic flow in one direction while blocking reverse flow.

A non-return valve, also called a check valve, lets air flow in one direction and prevents it from returning in the opposite direction. It can help hold pressure, prevent back-flow and protect upstream components in pneumatic circuits.

Pneumatic accessories are easy to overlook, but they have a direct effect on the efficiency and reliability of an air system. The wrong fitting or substitute component can leak, restrict flow or fail under vibration, while continuous air loss increases compressor running costs. A genuine ASCO accessory matched to the installation helps keep the pneumatic circuit tidy, reliable and easy to service.

The ASCO 34602126 is a metal-body valve from ASCO's Series 346 range of pneumatic line accessories. Its passive design requires no electrical connection, making it straightforward to integrate into compressed-air circuits.

Frequently Asked Questions

What does a non-return valve do?
It allows compressed air to pass in one direction while blocking reverse flow. This helps prevent back-flow and can help maintain pressure in a pneumatic circuit.

How do I install the 34602126 the right way round?
Follow the flow arrow marked on the valve body. The arrow should point in the direction in which you want air to flow.

What port size is the 34602126?
The ASCO 34602126 has G1/2 connections. Check that your fittings and pneumatic tubing are compatible before installation.

Should I choose the 34602126 or another ASCO model?
Start with the required port size, valve function and pneumatic circuit requirements. The 34602126 offers G1/2 ports. If you need G1/8 ports, the ASCO 34602124 may suit better. If you need a quick exhaust function instead, the ASCO 34600138 may be more suitable. Contact our team to confirm.

How should I maintain the 34602126?
Use clean, dry, filtered air where applicable, inspect the connections for leaks during routine maintenance and replace the valve if it shows damage, excessive wear or unreliable operation.

What is the most common mistake with pneumatic accessories?
Mismatching thread or tube sizes is a common installation problem. Confirm the connection size, airflow direction and compatible valve series before ordering.
