insulating gas valves couplings – Synergy Power Systems

When using the DILO coupling system a leak rate of better than 1 x 10-8 mbar l/sec. is achieved corresponding to less than 1 cm³ in 3 years. The DILO seal principle prevents the loss of Sulfr hexafluoride gas and moisture from penetrating the gaz sf6 gas system. DILO couplings will eliminate the loss of Sulfr hexafluoride gas by incorrect gas handling.

VALVE SIZING REFERENCE GUIDE - Norriseal-WellMark

A control valve may be defined as a valve with a powered actuator that responds to an external signal. The signal usually comes from a controller. The controller and valve together form a basic control loop. The control valve is seldom full open or closed but in an intermediate position controlling the flow of fluid through the valve.
