Product description

The oil and gas production increasingly develops regions, in which the ambient conditions make high demands on the installations and tools. The installations have to reliably operate also at temperatures of up to -60°C or withstand the climate and the seawater on offshore production or transportation facilities.

Many drive functions are performed hydraulically in these installations and therefore provide the necessary power within a small installation space. Wandfluh has a wide range of hydraulic valves, which have been tailored to the requirements of these special ambient conditions. In the field of surface protection, the external valve components are manufactured out of seawater resistant, stainless steel. With this »K9« standard, Wandfluh provides all important valve functions: from the directional valve via the leakage-free poppet valve right up to the pressure and flow control valves. The adjustment of the valve may take place manually or through a solenoid. If movements are to be made with changing speeds or with variable forces, the necessary valves are also available with a proportional function.
Specifically in the oil and gas applications electrically actuated valves are naturally utilised in explosion-hazard areas. Therefore, for the solenoid a corresponding protection has to be provided, which encapsulates possible sparks and limits surface temperatures, to exclude any ignition source. For this purpose, Wandfluh provides a solenoid with many international and national certifications and corresponding certificates. By the zinc/nickel surface coating, a maximum degree of corrosion-protection is assured (> 800h salt-spray test according to EN ISO 9227), which enables a problem-free use of the solenoid also in a corrosive atmosphere.
