Pressure Gauges, Transmitters and Relief Valves

From a pressure reducing valve to a simple pressure indicating gauge, we can help with almost any requirement.


With over 40 years combined experience in the specification, selection, installation and maintenance of a wide range of pressure regulators, Gas and Liquid Controls are uniquely positioned to help you with any requirements you may have.  From a simple point of use dual stage cylinder regulator, to a sophisticated pressure let down system, we can help provide you with the optimum solution.


We provide a diverse and comprehensive selection of back pressure regulators, addressing the intricate demands of various industries with precision and effectiveness. Our range of back pressure regulators is designed to meet the stringent requirements of applications spanning from chemical processing plants to refineries. Whether controlling pressure in complex industrial processes or ensuring stability in critical systems, our regulators offer versatility and reliability.


Pressure gauges are essential instruments for ensuring the accurate measurement and monitoring of pressure levels in a wide range of applications. Supplied in a wide variety of sizes, accuracies and ranges from 0 – 10 in. H2O through 0-100,000 psi. Our choices include differential pressure gauges, test gauges, sanitary gauges, high-purity gauges, subsea gauges, digital pressure gauges, OEM pressure gauges and more.


Our pressure sensors, pressure transducers and pressure transmitters are designed to meet harsh installations demands for low or high temperatures, high shock and vibration. We offer a wide selection of models for HVAC/R, food industry, pharmaceutical, off road vehicles, hydraulic and pneumatic and the semiconductor industry. Together they measure ranges from 0-0.01 in. H2O to 72,000 psi and accuracies from ±0.25% to ±2.00% of span. A selection of electrical terminations, process connections and analog outputs provide a custom fit for nearly any application.


We boast an extensive array of pressure relief valves, catering to diverse industrial needs with precision and reliability. Our comprehensive range of valves are designed to mitigate excessive pressure in various gas and liquid systems. Whether in petrochemical plants, manufacturing facilities, scientific research facilities etc, our valves are engineered to meet stringent standards and ensure optimal performance. From pilot-operated relief valves to cryogenic relief valves, we provide solutions that accommodate different pressure ranges and application requirements.
