The valve shall be made according to these specifications:
\n\u00b7high hydrodinamics section globe body, without stagnation pockets (low pressure loss type);
\n\u00b7standard ductile cast iron casting GS500\/GGG50, carbon steel casting on request;
\n\u00b7200\u00b0C furnace polyester powder paiting with 250 micron of minimum guaranteed thickness;
\n\u00b7plunger shaft entirely guided;
\n\u00b7particular plunger disc section and seat against cavitation risk;
\n\u00b7plunger shaft guide independent of seal seat;
\n\u00b7removible optional stainless steel seat, for higher cavitation resistance;
\n\u00b7obstacle free full port;
\n\u00b7neither spoke nor gride interposed in closing passage section to reduce maintenance and possible clogging;
\n\u00b7optional assembly of dissipating cage obturator without valve modification, to dissipate higher pressure and stabilize the valve opening;
\n\u00b7stainless steel shaft and return spring;
\n\u00b7return spring must not be inside flow path to avoid further turbulences and clogging;
\n\u00b7stainless steel bolts fastening cover to main valve body;
\n\u00b7nylon reinforced Buna-N diaphragm,
\n\u00b7antiabrasion Polyurethane plunger seal disc;
\n\u00b7easy maintenance design and easy access to internal parts without removing the valve from the pipeline;
\n\u00b7easy maintenance system, shall not be present any
\nconnection between the main body valve and the control circuit. All the pressure or command connection shall be connected only over the cover of the valve;
\n\u00b7possible maintenance intervention on pilot circuit even with operating valve;
\n\u00b7drain plug (optional) on valve bottom for total drainage in case of frost;
\n\u00b7main function pressure gauge for pilot calibration included, optional pressure gauge on demand;
\n\u00b7valve functions can be changed or added by simple pilot circuit modification.
\n.STANDARDS CONFORMITY
\n\u00b7Flange to flange: UNI-EN 558-1, DIN 3202 serie F5.
\n\u00b7Flange drilling: ISO PN10-16, on request compatible ANSI 150-300.
