All Categories
Not sure which valve fits your process?
Electric quarter-turn and multi-turn actuators – including IP67 explosion-proof and IP68 waterproof versions – pneumatic rack-and-pinion, linear-stroke and diaphragm actuators, and the accessories that complete the package. Supplied alone or mounted and tested on DELCO valves.
Product Range
Motorized ball, butterfly, gate, knife gate, diaphragm and globe valves driven by DELCO electric actuators – on/off, regulating and intelligent types with explosion-proof and waterproof (IP65 / IP67 / IP68) options.
Product Range
Ball, butterfly and process valves with single acting (spring return) or double acting pneumatic actuators: rapid actuation, precise flow control and low energy consumption, with positioners, limit switch boxes, solenoid valves and F.R.L units available.
Product Range
Electric, pneumatic and self-operated control valves for precise flow, pressure and temperature regulation – single-seat, three-way, temperature control and nitrogen blanketing designs, with or without handwheel.
Hydraulically actuated ball and butterfly valves in flanged, threaded and wafer versions. Share your medium, pressure, size and available hydraulic power, and our engineers will propose a suitable valve and actuator configuration.
Direct-acting, pilot diaphragm and pilot piston solenoid valves for water, air, steam and corrosive media – with high-pressure, high-temperature, explosion-proof coil, anti-corrosion, waterproof and pulse versions.
Product Range
Manual ball, butterfly, gate, knife gate, globe and needle valves in stainless steel, cast iron, plastic and fluorine-lined versions, with lever, handwheel or worm gear operation.
Spring-loaded safety valves in flanged, threaded, welded and sanitary versions – including steam, enclosed and high-temperature / high-pressure designs – that protect equipment and pipelines from overpressure.
Pressure reducing valves, Y-strainers, check valves, steam traps and other process valves – everything needed around your automated valves, from one supplier.
Flow meters, temperature sensors, expansion joints, flexible hoses, fittings and flanges, supplied together with your valves for one-stop procurement.
Every automated valve leaves our factory as a complete, tested assembly. Choose the actuator, fail-safe mode, control signal and accessories you need – we fit and test them on the valve before shipment.
Quarter-turn and multi-turn electric actuators for on/off, regulating and intelligent control.
Rack-and-pinion, linear-stroke, diaphragm and piston-yoke actuators for fast, reliable automation.
Everything that turns an actuator into a complete control package, mounted and tested on the valve.
From a colour change to a completely new valve design: our in-house R&D, ODM moulding and machining let us adapt standard DELCO products or build to your drawings.

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.
