Product Usage:
Metallurgy, petrochemicals, pharmaceuticals, food, healthcare, mechanical environmental protection, liquid level tank drop discharge and other fields. Suitable for pipeline systems with medium to large diameters and working pressures ranging from zero to low.
Structural features:
A valve that combines direct acting and pilot operated modes;
The valve core is a stainless steel piston type, and the piston ring will not be stuck by the medium;
The coil starts the valve core and simultaneously pulls the piston, which can work normally at zero pressure;
Autocratic coil, not easy to burn out, can be restarted after a long time of stopping action, with equally sensitive action and long service life

working principle:
Normally closed type: When the coil is energized, the electromagnetic force line opens the pilot hole, and the pressure in the upper chamber of the main valve piston decreases, thereby using the pressure difference and electromagnetic force to attract the pilot valve core and interlock with the main piston, and the valve port opens; When the power is cut off, the pilot hole is closed by the spring reset, and the upper chamber of the main piston is pressurized, pushing the main piston downward and closing the valve.
The opposite of normally open and normally closed.
Note: If the pressure at the outlet end is greater than that at the inlet end, the medium will conduct in reverse. Can install check valves or customize valves with built-in check function.
