Hydromodul-C Pressure Support 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.
