Hydromodul-C Altimetric Control Valve

The valve shall be made according to these specifications:
·high hydrodinamics section globe body, without stagnation pockets (low pressure loss type);
·standard ductile cast iron casting GS500/GGG50, carbon steel casting on request;
·200°C furnace polyester powder paiting with 250 micron of minimum guaranteed thickness;
·plunger shaft entirely guided;
·particular plunger disc section and seat against cavitation risk;
·plunger shaft guide independent of seal seat;
·removible optional stainless steel seat, for higher cavitation resistance;
·obstacle free full port;
·neither spoke nor gride interposed in closing passage section to reduce maintenance and possible clogging;
·optional assembly of dissipating cage obturator without valve modification, to dissipate higher pressure and stabilize the valve opening;
·stainless steel shaft and return spring;
·return spring must not be inside flow path to avoid further turbulences and clogging;
·stainless steel bolts fastening cover to main valve body;
·nylon reinforced Buna-N diaphragm,
·antiabrasion Polyurethane plunger seal disc;
·easy maintenance design and easy access to internal parts without removing the valve from the pipeline;
·easy maintenance system, shall not be present any
connection 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;
·possible maintenance intervention on pilot circuit even with operating valve;
·drain plug (optional) on valve bottom for total drainage in case of frost;
·main function pressure gauge for pilot calibration included, optional pressure gauge on demand;
·valve functions can be changed or added by simple pilot circuit modification.
.STANDARDS CONFORMITY
