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.
