Samson control valves

We supply Samson control valves in the UK as part of our independent multi-brand range. Samson has made control valves since 1907 and builds its actuators and positioners, from DN 15 globe valves to PN 400 high-pressure valves, and we specify the valve and positioner to the loop and back them with installation, maintenance and calibration support.

Flanged globe control valve with a diaphragm actuator and positioner mounted on the bonnet.

Built for the loop.

Type 3241 globe valves from DN 15 to DN 300 at PN 10 to 40, and Type 3251 high-pressure valves to DN 500 and PN 400, rated -196 to +550°C in cast iron, cast steel, stainless and forged bodies with metal, soft, ceramic and low-noise or anti-cavitation trims. Bellows seals and cryogenic extensions cover steam, thermal oil and liquefied gas lines.

Specified to the process.

Send us the medium, inlet and outlet pressure, temperature, flow range and the characteristic you need, and we’ll size the valve and match the actuator and positioner. Type 3730 positioners carry HART and SIL 2 approval with built-in valve diagnostics, and self-operated regulators hold pressure, temperature or flow with no air or power supply.

Range

Samson control valves we supply

  • Control valves

    Globe, rotary plug, segmented ball and butterfly valves for throttling and on/off duty. Modular design allows sizes, materials, trims and pressure ratings to be matched to the process, including cryogenic and steam-conditioning versions.

  • Actuators & positioners

    Pneumatic and electric actuators with matching positioners and accessories, sized to the valve from DN 15 upwards. Fail-safe action available, with digital communication for integration into plant control systems.

  • Self-operated regulators

    Pressure, temperature, differential pressure and flow regulators that operate without external power or air supply. Ideal for remote or hard-to-reach locations where running a supply isn't practical.

    Resolving unstable steam control at a dairy

    The valves looked correctly specified on paper. Resizing them ended what the dairy called steam wobble.
