Product Overview
Before anyone works on a pneumatic machine, the compressed-air supply needs to be isolated and secured. The ASCO 34304018 is a padlockable 3/2 isolation valve with G1/4 ports, designed to provide a clear shut-off point for pneumatic equipment.
A pneumatic isolation valve shuts off the compressed-air supply to a machine or circuit. In a 3/2 configuration, closing the valve can also vent downstream air, helping release stored pneumatic energy from cylinders and actuators before maintenance begins.
Pneumatic accessories are easy to overlook, but they directly affect the efficiency and reliability of an air system. The wrong fitting or substitute component can leak, restrict airflow or fail under vibration, while continuous air leakage increases compressor operating costs. A genuine ASCO accessory matched to the installation helps maintain a reliable, leak-tight and serviceable pneumatic circuit.
The padlockable design allows maintenance personnel to secure the valve in the isolated position as part of a lockout/tagout (LOTO) procedure. Always confirm the exact isolation function and lockout arrangement on the ASCO 34304018 nameplate and datasheet and follow the site's approved safety procedure.
Need a different port size? Compare the ASCO 34303015 (G1/2 ports), and keep the same installation approach.

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
-
Pneumatic systems requiring controlled isolation and downstream venting
How to Specify & Install It
-
Fit the ASCO 34304018 at the machine's main air inlet, upstream of the valve terminal, with the flow direction as marked.
-
Connect the G1/4 ports using suitable fittings and compatible thread sealant, keeping the exhaust port clear.
-
Switch the valve to the isolated position and verify that downstream pressure has fallen to zero before maintenance begins.
-
Where lockout is required, secure the valve in the off position using an approved personal padlock and the site's LOTO procedure.
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 configuration 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 conventional 2-way shut-off valve can leave compressed air trapped downstream. A 3/2 isolation valve can provide a venting function, helping remove stored pneumatic energy before maintenance.
What port size is the 34304018?
The ASCO 34304018 has G1/4 connections with a 3/2, padlockable function. Check that your fittings and pneumatic tubing are compatible before installation.
Should I choose the 34304018 or another ASCO model?
Start with the required port size, isolation function and LOTO requirements. The 34304018 offers G1/4 ports with a 3/2, padlockable configuration. If you need G1/2 ports, the ASCO 34303015 may suit better. Contact our team to confirm.
How should I maintain the 34304018?
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.
