Copper and zinc have rice material made of composite material. It is produced by precise processing in molding and CNC machines in molds. MS58 FAF brand rice valves produced from rice. It has high durability and impact resistance at low temperature. The valves are suitable for line installation on the pipeline, the main purpose is to open and close the flow in distribution systems. Recommended for open / closed applications. When subjected to pressure in half open position, sealing gaskets may shift from the bed. Care should be taken to wrap the valve body with a wet cloth or not to use connection equipment that damages the valve slots and tooth sealing. DN 15 -50 diameters are produced in PN 25 pressure class and in DN 65 -100 diameters in PN 16 pressure class. TSE 13547-B3 provides table values. In cases where the operating temperature is high, the pressure value decreases down. Get information from our company for high temperature strength values of sealing gaskets. The pipe should be shorter than the tooth neck on the body.
