D P Controls LLP

Process Automation

We serve the oil and gas, power and nuclear industries with precision instruments that measure pressure, level, temperature and flow. No company builds a better product, and no company backs their products with better warranties or better customer service. SOR products are the standard for quality, reliability and durability.

One reason for our continued worldwide growth is the willingness to listen to our customers´ specific needs and develop customized solutions to meet those needs. In fact, a majority of the products SOR manufactures and delivers are specially engineered to order. New products continue to be engineered and developed that integrate features such as wireless and smart technologies.

There are SOR instruments built decades ago that are still in the field, in the harshest environments, doing their jobs every minute of every day. In 1993, SOR earned the highest level of quality registration - ISO:9001 - and we´ve continued to achieve that goal every year since. Quality is the hallmark of our products.

Valves & Controls

  • 1450_Control-Valve

  • Liquid Level Controller

Control Valves


1450 Close-Coupled Control (Dump) valve (NACE Certified)

Designed to meet the high pressure and erosive applications common to the oil and gas industry. These valves are ideally suited for process media control applications including: controlling liquid level on 2 or 3 phase gas separators, gas dehydrators, compressors, scrubbers, heater treaters and well test systems, as well as other oil field equipment.

1451 Freezless control (Dump) valve

Perfectly suited for fluid control in oil and gas separators and other process vessels. The plug and seat are able to be constantly submerged in the process media due to the valve body design, thus giving the valve its "freezeless" characteristic. NACE MR0175 compliance option

Level Controller


1600/1601 Liquid Level Controller

Rugged and versatile design and are ideal for oilfield scrubber and separator applications. The 1600 series controllers are available in pneumatic snap and throttling pilots, or electric SPDT and SPDT limit switches; direct or reverse action; with a variety of displacer sizes, materials, and vessel connections

Pressure Regulator



1267AFR-1
1267AFR-2 High Flow Capacity
Range 0-30, 0-60, 0-120 psi
