Hydromodul-C Valve Electric

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
