8881909104	waste water	3.3 ft (1.00 m)	250 PSI (17.2 bar)	3" ANSI	Flange	Stainless Steel	8881909104 Medium: waste water Specification:Air Valve Set for Underground Installation, stainless steel Operating Range: 0 – 250 psi, ( Model # 986-04 ) Automatic Air and Vacuum Valves shall be infinitely variable automatic air and vacuum valves designed to allow escape of air for a operating range starting from pressure range: 0,0 through 250 psi ( 0 – 17,2 bar ), close watertight when liquid enters the valve even when the fluid is rising without pressure ( no minimum operating pressure required), allow air to enter in the event of a vacuum, and soft working behaviour as water hammer inhibition realized by roll-on diaphragm and spring mechanism. When the sealing device of the valve is closed an air cushion is trapped between the fluid and sealing area, a mud deflector made of PE allows no contact between fluid and sealing area. The valve body and spindle spring shall be stainless steel grade 316Ti, designed to facilitate disassembly for cleaning and maintenance. The float shall be Delrin® ( POM ); the valve seat and all working parts shall be of corrosion resistant materials. Valves shall be equipped with the necessary attachments, including ball valve, to permit back flushing after installation without dismantling the valve. Valves shall be recommended by the manufacturer for wastewater service. The air valve set is provided with a PE shaft replacing a manhole, a shut-off device with a steel plate of hard-rolled stainless steel and straight-through bore when open, two maintenance outlets with hose connection and ball valve, lateral outlet for waste air with PE elbow as swivelling device equipped with additional protection grid, drain-off fitting at the shaft bottom. After closing the shut-off device by integrated operating tool and removal of the upper ball valve the air valve can be taken out of the shaft for maintenance purposes.
