Compressed air turns a ball or butterfly valve quickly and reliably, with no motor to overheat. Every DELCO pneumatic valve is supplied as a complete assembly – valve, actuator and accessories matched, mounted and tested together.
Compressed air strokes the valve quickly – ideal for emergency shut-off and frequent on/off cycling.
Spring-return versions move to a fail-safe position on air loss; double acting versions hold their last position.
Add a 4–20 mA positioner and the valve modulates flow accurately from your PLC or DCS.
Air drive creates no sparks – with explosion-proof solenoid valves and switches it suits hazardous areas.
Air is only used while the valve moves, keeping running costs low across large numbers of valves.
Solenoid valve, limit switch box, positioner, F.R.L and manual override, mounted before shipment.
From clean water to abrasive slurry, DELCO valves automate shut-off and control in demanding process plants. Explore the valve solutions for your industry.

View SolutionA pneumatic actuated valve is a complete assembly. Getting three decisions right up front saves a round of questions and gets you an accurate quotation faster.
Air drives the valve one way, springs return it. On air or power failure the valve moves to its fail-safe position – the choice for emergency shut-down.
Air drives the valve both open and closed, and it stays in its last position if the air supply fails. A compact choice for standard on/off duty.

We are an in-house manufacturer for automated control valves and actuator assemblies. All core processes including casting, CNC machining, assembly and performance testing are completed in our own factory. OEM & ODM services are supported.
Our standard lead time is 7–15 working days, with expedited options available for urgent projects. For custom valves, the delivery date is confirmed with your quotation once drawings and specifications are approved.
Yes. As an OEM & ODM manufacturer we build valves and actuator assemblies to your drawings or specifications – custom painting colour, dimensions, connections, accessories and your own brand. Our engineers also provide 2D & 3D CAD models for your project approval.
Every valve passes 100% pressure and function testing before shipment. Depending on the order, documents include pressure and sealing test reports, Material Test Certificates (MTC: chemical analysis, corrosion, mechanical and impact tests) and actuator test reports such as the IP65 protection grade test.
Our production follows an ISO 9001:2015 quality management system and our products carry CE, RoHS and FDA certifications. Valves are tested according to API 598, API 6D, EN 12266-1 or your own specifications.
DELCO valves come with a 12-month standard warranty covering manufacturing defects, including free parts. Extended service contracts are available on request, backed by 24/7 technical support by phone, email or video call.
Yes. We have no minimum order quantity, so you can start with a trial order to check our quality before moving on to volume projects. Samples can be arranged after price confirmation.
