SAMSON AG

Founded in 1916, the German firm SAMSON AG has established itself as a prominent figure in the manufacturing of shut-off and control valves. Throughout its history, the company has evolved into a worldwide leader in this sector. SAMSON AG’s control valves find extensive application across various industries, including chemicals, gas, oil, petrochemicals, pharmaceuticals, and healthcare. These valves are engineered to accommodate a wide range of contemporary technological processes, ensuring efficiency and reliability in operation.

Today, SAMSON AG is part of the SAMSON GROUP holding. In addition to SAMSON AG, the holding includes AIR TORQUE, CERA SYSTEM, KT Elektronik, LEUSCH, Pfeiffer, SAMSOMATIC, STAR Line, and VETEC.

Below is the range of products manufactured by SAMSON AG.

Regulators

Used in water supply systems, hydraulic engineering, industry, and power plants.

Temperature Regulators

Direct-acting temperature regulators utilize the energy of the medium for regulation, operating on the principle of fluid expansion. They consist of a control valve and a control thermostat, providing high reliability in operation. Suitable for temperatures up to 350°C.

SAMSON AG temperature regulator series include 1u, 4u, 1/2212, 1/2213, 4/2212, 4/2213, 2231, 2232, 2233, 2234, 2235, 2212 (STB), and 2213 (STW).

Pressure Regulators

Direct-acting pressure regulators use the energy of the working medium, providing sufficient force to operate the control element—the plunger rod and plunger. They consist of a valve and an actuator that opens or closes the valve in response to pressure changes. Any deviation from the set value corresponds to a specific position of the valve plunger.

SAMSON AG pressure regulator series include 2333, 2334, 2335, 2373, 2375, 2405, 2406, 2407, 2408, 2434, 1/2401, 2357-1/6, 2357-11, 2357-11, 2357-2/7, 2357-21, 2357-21, 2357-3, 2357-31, 2371-00, 2371-01, 2371-11, 2422/2424, 2422/2425, 33-1, 33-7, 36-3, 36-8, 39-2, 4/2401, 41-23, 41-73, 44-0 B, 44-1 B, 44-2, 44-3, 44-4, 44-6 B, 44-7, 44-8, 44-9, 50 ES, 50 EM, 8/2401, 9/2401, M 44-2, and M 44-7.

Differential Pressure and Flow Regulators

Proportional regulators that operate using the medium’s energy. Any deviation from the setpoint causes a corresponding adjustment of the valve plunger. When the actual differential pressure deviates from the set value, the resulting force moves the plunger. The precision and stability of regulation depend on external influences on the regulator. These regulators are designed to minimize the impact of external factors using a compensating metal bellows.

SAMSON AG differential pressure and flow regulator series include 42-10 RS, 42-20, 42-24 A, 42-24 B, 42-24 DoT, 42-25, 42-28 A, 42-28 B, 42-28 DoT, 42-34, 42-34 DoT, 42-36, 42-36 DoT, 42-36 E, 42-37, 42-37 DoT, 42-38, 42-38 DoT, 42-39, and 42-39 DoT.
