Sern Ball Valves manufacture three-piece forged trunnion design ball valves that can be Double Block & Bleed, Bi-Directional or to suit a Double Piston Effect as required for the Oil and Gas Industries.

Sizes: 1” (DN25) through to 32” (DN800)

Pressure Classes: 150# through to 2500#

The valves are certified SIL 2, and are Fire Safe to API607.

Please contact us for more information or a quotation.



AMG-Pesch manufacture a range of compact rack & pinion actuators, either Fail Safe or Double Acting.

The actuator pistons are secured in their linear travel by the guide rods which are designed to prevent radial torsion of the pistons, ensuring a uniform surface pressure of the teeth surfaces of the pinion shaft and the guide rods. The power transmission is kept constant and the material wear reduced to a minimum.

Double acting actuators are available in torques ranging from 4.5Nm to a maximum of 7,051Nm.

Spring return fail safe actuators can be sized from 2 Barg minimum air supply and are available in torques ranging from 3.9Nm to a maximum of 3,627Nm.

The actuators conform to PED, ATEX and can be rated up to SIL 3.
