New Control Solution with Proven Parts Type 3291 Valve

The valve was specifically developed for application in the oil and gas industry. Its construction is based on the proven SAMSON valve design, but instead of being screwed in place, the valve's seat is clamped in. Contrary to the widespread cage valves, the SAMSON valve generates very little friction during operation and is resistant to dirt deposits and leakage.

Aseptic Valves

Germs don't stand a chance in the body of the Type 3347 Aseptic Valve, which has no dead spaces because the process medium only touches parts made of polished stainless steel.

The Type 41-23 and Type 41-73 Pressure Regulators are suitable for liquids, gases and vapors. They do not need any auxiliary energy as the energy required to regulate is taken from the process medium.
