Rotary Valves

SAMSON Group manufactures ball, segmented ball, butterfly, and eccentric rotary plug valves for non-corrosive, corrosive, and erosive media that conform to rigid ANSI, API, and ASME standards for both on/off and throttling service.

The valves are made in a variety of materials (ceramic, PFA/PTFE lined, carbon steel, alloy steel, stainless steel, Duplex, Monel, titanium, Hastelloy, Inconel, SMO, bronze, etc.) for use in many industries, such as oil and gas, chemical, petrochemical, pulp and paper, nuclear and conventional power, waste water, and mining and extraction. Rotary valves are offered in low or high pressure classes for light or heavy industrial applications.

Ball Valves 

SAMSON Group manufactures top and side entry, floating and trunnion ball valves in sizes from one-half inch up to forty-two inches or larger depending on your need. Ball valves can be ordered with metal, graphite or soft seats and different sealing options to suit the requirements of your processes.

Butterfly Valves 

SAMSON Group high performance, centric, double eccentric and triple eccentric butterfly valves range in sizes from two inches up to one hundred inches or larger, if needed, for better control or tight shut-off.  Valves are offered in a selection of materials. Customized butterfly valves specially designed for cryogenic applications, anti-surge requirements, or with low noise trim are also available.

Eccentric Rotary Plug Valves

Rotary plug valves are a combination of a ball valve, butterfly valve and a classic globe control valve with an unobstructed flow path that is free of dead space and maintains control of high pressure drops. Cost saving occurs when ordering plug valves because the Cv coefficients can reach up to 200% higher than those of globe valves.  A smaller valve can be used to maintain control of the flow. SAMSON Group eccentric rotary plug valves are manufactured in sizes one inch to twenty inches for throttling or on/off service.

SAMSON offers a wide selection of rotary valves to provide you with the valve that best meets your needs to maintain control in your processes while reducing costs, meeting mechanical and safety requirements, and limiting your process down time.
