Extraction, transport and processing of oil and gas often take place in harsh conditions – extreme climates, offshore sites and hazardous areas. Valves need a long service life, reliable shut-off and corrosion resistance.
The oil and gas sector provides the fuels and lubricants we use every day. Extraction and processing usually take place under harsh conditions – extreme climates, offshore sites and explosive atmospheres – so valves need a long service life, reliable shut-off and proven corrosion resistance.
DELCO supplies automated ball, butterfly and control valves with electric or pneumatic actuators, together with safety and manual valves, for every stage of the value chain.
Wellheads, gathering lines, separators and chemical injection.
Block valve, metering and compressor stations on remote routes.
Process units, utilities, tank farms and loading terminals.
Topside process, produced water and utility systems.
Pressure & function tests per API 6D, API 598 and EN 12266-1
Installation photos and project data from the DELCO catalogue – from an Arctic gas pipeline to a desert petrochemical plant and a North Sea platform.
Automated shut-off valves for the expansion of a petrochemical plant, installed on oil & gas processing lines in a hot desert climate.
Siberian Arctic gas pipeline expansion (Yamotlor field operations), where valves must operate reliably in hazardous areas and extreme cold.
Equinor’s Statfjord B platform, a 45-year-old North Sea offshore facility, experienced chronic failures in its produced water treatment system.
Every oil & gas duty is different. These are the DELCO valve types our engineers select most often – and why. Send us your media, pressure, temperature and area classification for a project-specific recommendation.
Explosion-proof electric actuators and ATEX-rated options for Zone 1 / Zone 2 locations.
Actuators and seals selected for Arctic cold or desert heat on exposed sites.
Stainless, lined and HVOF-coated options for sour service to NACE MR0175 / ISO 15156.
Every valve pressure and function tested per API 6D, API 598 or EN 12266-1.
Why: quarter-turn full-bore ball valve with a pneumatic actuator - fast, tight shut-off and a spring-return option that closes the valve on air or signal loss. The standard choice for automated isolation and emergency shutdown on process lines.
Why: where no instrument air is available - remote pipelines, wellsites and tank farms - an explosion-proof electric actuator drives the valve from an on/off or 4-20 mA signal, with local position indication and manual override.
Why: globe control valve with a diaphragm actuator and smart positioner for stable modulating control of pressure, level and flow - separators, fuel gas conditioning, heaters and utility loops.
Why: compact high-pressure body for small-bore lines where standard ball valves are not rated - chemical injection, instrument gas, sampling and auxiliary wellhead lines, with automated on/off control.
Why: automate new or existing valves in hazardous areas. Quarter-turn and multi-turn versions with explosion-proof enclosures; the LQ explosion-proof series reaches up to 6000 Nm for large-bore valves.
Why: spring-loaded safety valves protect vessels, separators and pipelines against overpressure - the last line of defence on every pressure system, for gas, steam and liquid service.

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.
