Product Overview
A main air drop into a machine needs a reliable way to shut off the compressed-air supply during maintenance. The ASCO 34303015 is an isolation valve with G1/2 ports, making it suitable for machine air supplies and higher-flow pneumatic circuits.
A pneumatic isolation valve shuts off the compressed-air supply to a machine or circuit. In a 3/2 design, closing the valve can also vent downstream air, helping release stored pneumatic energy before maintenance work begins.
Accessories are easy to overlook, but they have a direct effect on the efficiency and reliability of a pneumatic circuit. The wrong fitting or substitute component can leak, restrict airflow or fail under vibration, while continuous air leakage increases compressor running costs. A genuine ASCO accessory matched to the installation helps maintain a tidy, reliable and serviceable pneumatic system.
Padlockable isolation arrangements can also support maintenance lockout/tagout procedures. Confirm the exact function, port configuration and lockout features of the ASCO 34303015 against the product nameplate, datasheet and your site's safety procedure before installation.

Who This Product Is Best For
-
Machine builders adding a safe air-isolation point
-
Maintenance teams formalising pneumatic LOTO procedures
-
Plants replacing worn or non-lockable shut-off valves
How to Specify & Install It
-
Fit the ASCO 34303015 at the machine's main air inlet, upstream of the valve terminal, with the flow direction as marked.
-
Connect the G1/2 ports using suitable fittings and compatible thread sealant, keeping any exhaust port clear.
-
Switch the valve off and verify that downstream pressure has fallen to zero before maintenance begins.
-
Where lockout is required, secure the valve in the off position using the site's approved LOTO procedure and suitable lockout equipment.
Frequently Asked Questions
What does a pneumatic isolation valve do?
It shuts off compressed air to a machine or pneumatic circuit so maintenance can be performed safely. A 3/2 isolation arrangement can also vent trapped downstream air, helping release stored pneumatic energy.
Why use a 3/2 isolation valve instead of a simple ball valve?
A plain 2-way shut-off valve can leave compressed air trapped downstream. A 3/2 isolation valve can provide a venting function, helping remove stored air before maintenance.
What port size is the 34303015?
The ASCO 34303015 has G1/2 connections. Check that your fittings and pneumatic tubing are compatible before installation.
Should I choose the 34303015 or another ASCO model?
Start with the required port size, valve function and maintenance requirements. The 34303015 offers G1/2 ports. If you need G1/4 ports with a 3/2, padlockable configuration, the ASCO 34304018 may suit better. Contact our team to confirm.
How should I maintain the 34303015?
Use clean, dry, filtered air where applicable, inspect 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, valve function and compatible pneumatic components before ordering.
