ANC valvesare globe type valves with symmetric body and heating jacket integrated to the body casting.
The heating jacketed valves distributed by RIT are designed to stop, divert, measure and control all high viscosity liquids as bitumen, coals and high density fuel oils.
The standardization of all manufacturing components enable to produce different models of control valves in 2 and 3-way version.
The ANC valves for bitumen are used by the major manufacturers of asphalt mixing plants thanks to the specific features and reliability.
The most important advantages are the extremely simple design and the symetric body with wide poening allowing an easy maintenance,the casted thermal jacket, the rugged single acting air cylinder "air to open" whith ensures a long service life even at the extreme temperature,the 3 position actuator for dual flow rate control with adjustable closure rate, given by a mechanical air released locking device.
It is particulary easy to fit position indicator microswitches.
The minimum operating air pressure is given on attached file. For operating temperature up to 160°C a plag with soft sealing my by adopted ;for higher temperature up to 300°C a corrosion resistant aluminium alloy plug, without sealing is required.
