Hydraulic/pneumatic Pressurization skid.Semi-automatic control with command on control console. Each process element (valves & pump) is controlled by the operator by luminous pushbuttons. Leak could be measured (option) by electronic bubbles 2 counter or precision water column for H O leak (height measured by pressure transmitter). Vacuum pump could be installed (option) to assure the absence of air inside valve's body before filling it with water; in order to reduce test time and increase operator's safety. All wet process components are stainless steel made and dimensioned for a working pressure of 700 bar . It has a high filling flow ability and the recovering of test fluid is automatic. Metal to metal needle valves assure high reliability. (up to 2100 bar as option) The "manual" nature of this skid, allow the operator to perform test on the valve (or test sequences) non contemplated into the reference test standard.
