Standard Enclosures: Red-Hat II -- Types 1, 2, 3, 3S, 4 and 4X Combination General Purpose and Watertight. Optional Enclosures: Red-Hat II -- Types 3, 3S, 4, 4X, 6, 6P, 7 and 9 Combination Explosionproof and Watertight. To order, add prefix "EF" to catalog number. Additional constructions are available. The Optional Features Section contains descriptions and ordering information for: Open Frame Solenoids · Junction Box Enclosures · Panel Mount Constructions. Electrical: Standard Voltages: 24, 120, 240, 480 volts, AC, 60 Hz (or 110, 220 volts, AC, 50 Hz) 6, 12, 24, 120, 240 volts, DC Other voltages are available when required. Note: 125 and 250 volts, DC, are battery voltages applied in power plants. Special AC and DC constructions are available to pilot power plant control valves. Coil: Continuous duty molded Class F. Nominal Ambient Temperature Ranges: AC Construction: 32°F to 125°F. DC Construction: 32°F to 104°F Valve Parts in Contact with Fluids: Body -- Brass or 304 s.s., as listed Seals and Discs -- Buna "N"; Nylon upper disc for 8317 Series Diaphragm -- Neoprene for 8317 Series Core Tube -- 305 s.s. Core and Plugnut -- 430F s.s. Core Springs -- 302 s.s., 17-7PH s.s. Shading Coil -- Copper (brass body); Silver (stainless steel body) Pilot Seat Cartridge and Disc Holder -- Acetal for 8321 Series Piston - 303 s.s. for 8321 Series Approvals: CSA certified. UL listed General Purpose Valves. Ordering Information: Important: We must have catalog number, voltage and Hertz, operating pressure and fluid handled. Use strainers with Solenoid Valves. IMPORTANT FOR 8321 SERIES: A minimum operating pressure differential must be maintained between the pressure and exhaust ports. Supply and exhaust piping must be full area, unrestricted. ASCO flow controls and other similar components must be installed in the cylinder lines only. Pipe Size (ins.) Orifice Size (ins.) CV Flow Factor Operating Pressure Differential (psi) Max.
